They were actually 10-19. I caught this when doing up this December issue and realized I missed a measurement for the 19th. In my records for that date I had to enter 'away from sky'. Globe at Night starting in late November 2017 spells its name as 'Globe ...', no longer 'GLOBE. It also posted dates for the campaign in 2018, which are now n an updated NYSkies GaN webpage www.nyskies.org/gannyc.htm Cornelia Street Cafe' fixed its web, with full information about its shows. however, thee is no entry for its 'Entertaining science' even t in December 2017. Westoort Astro Soc has two meetings in December 2017, the 19th and 31sr. The second one begins at 16:00 and could be a New Year's Eve celebration. Please inquire at contact. Some readers forgot that the former 'Upstate' section is now named 'Metro-North' and thought it was missing from November's NYC Events. I put in a dummy section referring to the new one. City News ------- Astronaut Byzz Aldrin was Grand marshall at NYC Veterans Day parade on 2017 November 11. He, air force pilot in Korean War, joined a memorial wreath placement at Madison Sq, then rode with parade up 5th Av to 52nd St. NYC mayor deBlasio got a 2nd term on 2017 Nov 7, with ~65% of the votes. Runner up Melliotakis earned ~30% and all others filled out 5%. One useful project, started in summer 2017, is the huge expansion of Select Bus Service with ~25 new routes thruout the City. An other, already operating, is the free pre-K care for 3-5 YO children. vary ` I uploaded the first batch of 'Cosmological Models' the historical paper from the 1990s. It's reached by the jumpword 'CosmoModels' in the banner of the NYSkies homepage www.nyskies.org, punch ''CosmoModels' The page you land on explains the paper, with some history, and offers advice for reading it. Please do know ell that the treatment is not a trivial or trite one, like so many offered to home astronomers. You do have to study the letterpress and follow the maths. NYSkies Astronomy Seminar on November 2017 explored variable stars. These are stars with a changing energy output, not emitting a steady light. There are many ways a star's brightness can change with time . We studied pulsating stars, stars that evolved of of the Main Sequence to become red giants and supergiants. These stars no longer enjoy the constant energy production provided by converting hydrogen into helium. The core ran out of hydrogen and the core is too 'cold' to fuse helium into heavier elements. The core starts to collapse, heating the core into helium fusion. The flash of new energy shoves the outer layers of the start out to huge size, tens to hundreds of solar diameters. Helium fusion is more complex than hydrogen with many routes toward heavy elements. When first explored after WW II we assumed helium takes in a proton or an other helium, or alpha. These fusions make lithium-5 or berylium-8. These would merge with more protons and alphas to continue the element-building process and keep thee star shining. Li-5 and Be-8 are self-decaying, turning back to He+p or He-He almost instantly. They have no time to merge with other particles and the star should start to shut down with no heavy elements produced. We learned that nuclear research showed that if three alphas at once merge, they fuse into carbon-12, a stable isotope that then merges with other particles to make heavier elements. This is the triple-alpha method. During the red giant phase the energy generation shifts form a one to an other method, causing oscillations in emitted radiation. In addition, the star heaves and sighs with the varying outward radiation pressure and its spectrum changes with varying surface temperature. The star actually pulsates. In the heave phase some of the outer layers can loft away, exceding local escape speed, and form clouds or trails around the star. We examined pictures of close supergiants whose discs were resolved. They were patchy from dark/light zones. Mass loss can be tens of percent of the star's MS mass. The oscillations may be regular and cyclical or irregular and lazy. To study these stars we group them into categories of similar light profile, named for a prototype star. This may be the first discovered, best observed, brightest, most famous. Because most of the pulsating stars are really red in color, in the 19th century there was a fetish to examine all red stars for possible varying brightness. As the number of variable stars increased, with many without existing names, a nomenclatues was developed that is rather quirky. it turns out that the Bayer system never needed letters beyond Q in a constellation. After Bayer ran out of Greek letters, he used Latin letters, but no farther along than Q. The first variable star found in a constellation without a Bayer name is is given letter R. After variable star Z a double-letter scheme was used. When we ran out of double letters, we simply numbered all later stars V###.. Some constellation, in the Milky Way, do have 1500 and more Variable stars! Looking at a variable star, the pulsating ones for this session with one exception, requires handiness with the sky and a chart to follow the brightness changes. In the US the study of variable stars is handled thru the American Association of Variable Star Observers. In other countries there is a division or section within a national astronomy society. The autumn sky has several pulsating stars and one eclipsing binary star. The pulsating ones include delta Cephei, omicron Crti (Mira), alpha Orionis (Betelgeuse), eta Geminorum. The eclipsing star is beta Persei (Algol). Note that all of these already had Bayer ames when they were found as variables. Algol changes brightness from a dimmer star orbiting the main star in out line of sight. As the one or the other is in front the combined brightness changes from high to low in a regular cycle. The star was first studied in the 1780s with a suggestion that the dimming was caused by a dark body -- a planet? -- passing in front of the star. Takeaways were articles on pulsating stars, HR Daigram with categories of pulsating stars plotted in it, images of supergiant star discs and ejected matter, and charts for several autumn variable stars. On 31 October 2017 a rented pickup truck wrong-roaded on West Side Hy, MH, from Houston St to Chambers St. It charged along the bike lane, killing 8 and injuring a dozen people.The attack ended when the truck crashed into a school bus, injuring several children in it. Driver Sayfulhoh Sairpov jumped out of truck waving a paint gun and pellet gun. He was shot by NYPD and hospitalized. Under inquest he legally came to US in 2010 from Uzbekistan, earned a green card, and advocates the jihad ideology. Sunset Pk NK got go-ahead for its own Chinese arch at entrance to nabe on 2017 Nov 3. It will stand at 60-61 St & 8 Av. Arch is one of many donated by China to cities with large Chinese districts This is NYC's first, possibly others will be set up in manhattan's Chinatown and in northern Queens. On November 217, 2017, Brooklyn College began new rule requiring police in uniform to avail only of a couple designated restrooms on campus! Until now police could use any handy campus restroom while patrollilng or passing thru adjacent streets. NYSkies Astronomy Seminar on 17 November 2017 examined double stars. We reviewed the history of double star discovery soon after the telescope was applied to the stars. We learned how Galileo tried to get parallax from Mizar, believing its two stars were a line-up. For the rest of 1600s to late 1700s double stars were pretty curiosities of the sky for stargazers to admire. The two stars in the pair usually were of different color, according as their spectral class. We discussed the contrast as a physiological effect. Lights of pale color, like stars, when seen close together can seem to emit strong hues. In late 1700s Michell in mid 1700s deduced thru modelling and statistics that double stars were far too numerous for chance line- ups. He suggested they are real twin stars but had no way to prove this idea. Double stars were too casually recorded for good analysis in his time. Herschel tried for parallax on double stars but found after some ten years that most pairs were in mutual orbit, He and others showed the motion was gravity-driven, showing that newton's laws extended thruout observable space and not confined to the solar system.Sw examined diagrams of double star, now binary star, orbits to trace their motion over many decades. an astronomer can in many cases can see the motion during his career. We learned that binary stars are created along with single stars from their host nebula. Globules of protostellar gas form near enough to attach together by gravity and then become stars. This formation cancels out two major variables in stellar evolution: age and composition. The stars came into being together, within a few millennia, and are made of the same mix of elements. We explored Kepler's 3rd law and newton's modification. It yields the masses of the binary star, but only the sum of the two. From spectrometric radial velocity measures we get the ratio of the masses. The two equations in two unknowns determine the individual masses. We then saw how the binary stars plot on the HRD with many on the MS. When the star masses are noted on the MS, there is a strong linear relation of mass with luminosity or temperature. WE noted the caution for using lists of binary stars for observing. Since the stars orbit, their separation and rotation change with time. The list should include the year for the stated parameters, else there is no way to tell what the stars look like now. In some works on double stars there is a computer program to key in and compute the binary star parameters for any desired year, given the orbital description. We learned that until the orbiting astrophysical satellites we assumed binary stars are always two distinct stars with clear space between them. he satellites, working in UV and X-ray, found binaries of stars so close that they interact, commingling atmospheres and siphoning gas. Many of these stars are also emit erratic luminous radiation as variable stars. Many binaries have one component that evolved into a supernova, leaving a blackhole in orbit. We discussed the four main kinds of binary: telescopic or optical or visual, astrometric, spectrometric, and photometric. Astrometric binaries move thru space wither together as two visible stars side by side or as a single star tugged off course by a too-dim companion. Sirius is the first example of the latter kind, which eventually revealed its white dwarf companion. Spectrometric binaries reveal duplicity by shift in the spectral features. The spectral lines displace to the red and blue for each star in orbit. The photometric binaries are also called eclipsing binaries. The orbit is edge-on, making for eclipses on each revolution of the pair that shows up as a cyclical rise and fall of brightness. Takeaways were charts of several binary orbits, examples of spectrometric and astrometric binaries, articles on observing double stars. In mid November 217 US Coast Guard inspected three boats from the new NYC Ferry fleet. It found heavy pitting with many perforations in the boats's aluminum hull, causing the vessels to take in water. They, plus two others, were pulled off duty for repairs. NYC Ferry started in spring 2017 to link outer reaches of the City to Manhattan where there was no direct rapid transit route. Sky News ------ The Observer's Handbook offer has several books left, after passing a higher-than-usual number into astronomers's hands. if you still didn't request your co, do so immediately! The coupon is at www.nyskies.org/oh.hym November 217 gave us long runs of clear cool, sometimes chilly, nights with solid observing. Observers noted the abundance of dimmer stars in areas of sky often bare of stars. Many traced faint constellations and asterisms like Cetus, Lynx, Monoceros, Eridanus. First frost of 2017-2018 winter came to NYC on 2017 Nov 10, late night. Temps touched -2C with mild breeze. Freeze continued thru the 11th. Night sky was dark and clean, potentially allowing a Milky Way sighting. None reported because observers waited for orion to overtop skyline for GaN measurement, after summer Milky Way was setting. There is NO leapsecond at end of 31 December 2017. Last minute of the year has normal 60 seconds. UTC - TAI = 37s until further notice. Thanksgiving night, 2017 November 23, could have been a Milky Way night. Because essentially all astronomers were enjoying holiday festivities at nightfall, there probably will be no definite report of a sighting or not. The air was dark with transparency of almost 5th magnitude in most of the City. Minor constellations and asterisms were clearly visible. Neptune is getting too low ar nightfall for good viewing. Uranus is still in high sky near Aries. Astronomers are already looking toward spring-summer 2018 for the opposition of Mars. It is the closest since 2003, the next in the 15-year cycle of oppositions. The Geminid meteor shower peaks on 2017 December 15th. This falls within the dark Moon span of December's Globe at Night round, 9-18. In this century the Geminis meteor stream orbit seems to pass more directly over Earth. This is making stronger displays, about equal to the Perseids. The Geminids are unusual for having its radiant, near Castor-Pollux, in high sky before midnight.
