General News 
  ---------
    By a typo the dates for Globe at Night in November were listed as 
10-18. 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'

    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.

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

 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

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.

    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.
