period of 4.59 years.
It is a member of the Pleiades group and is a mercury-manganese star. These stars
(also called manganese stars) are of class B and have peculiar spectra where lines of
manganese and other exotic elements (such as mercury, gallium, yttrium) are strong.

This system is a famous eclipsing variable with a 12.91 day period. It has two
minima (since the two stars are unequal in brightness)— 3.8m and 4.3m separated by a
maximum of 3.4m in a 12.925 day period.
Only 0.24 AU separates the Aa pair, so mass transfer must occur (at about 10^22
grams per second in a river that flows at 180 miles per second, equal to 10^-5 suns per
year!). Eventually, the accumulation of material on the companion may alter its physics
to the point where it becomes a nova. In addition, we now know that the secondary is
also slinging off a stream of ejecta that forms an expanding spiral pattern.
The Aa stars are both oval-shaped owing to their strong gravitational warping of each
other. The dimensions of the larger star may be about 19 solar diameters by 13; for the
smaller companion, it is probably about 12 by 9 solar diameters.
Star A is 10 times the mass of the Sun; star a is 20 solar masses. Note that the
brighter star is the less massive; does Mass/Luminosity always hold? Some astronomers
think that the luminosity of star a may be reduced because it is surrounded by a
(hypothetical) accretion disk. The fact that the primary is also an infra-red source makes
this a possibility.

Zone 124
Beta Lyr stars are a fascinating sub-class, also known as W Ser stars. They are
always part of a binary system of two massive stars, one of which has aged faster and is a
giant that fills its Roche lobe, meaning there is significant mass transfer taking place.
This mass flow from the younger star to the older one results in an accretion disk around
the old star. The variabilities in this disk lead to variable light output and if the viewing
angle is just right (as it is in Beta Lyr's case), the disk will give the impression that the
older star is brighter than it really is.
The outer edge of the accretion disk can hide the "eating" star and make it look larger
and cooler than it really is, making it appear to be a giant instead of the Main Sequence
star it really is.
The stars show similar proper motions.
From James Kaler's Star Notes:
Sheliak derives from an Arabic word that refers to the whole constellation, to the
celestial harp itself, which in Greek mythology commemorates the harp of Orpheus. It is
not one star, but two, a bright bluish hotter one with a temperature of some 13,000
degrees Kelvin orbiting a dimmer white cooler one (though one still much brighter than
the Sun) with a temperature closer to 8,000 Kelvin Sheliak eclipses! The plane of the
orbit is pitched so that during an orbital period of 12.9 days each star gets in the way of
the other, the combined light of the system at minimum alternating between 30% and half
of normal every 6.5 days. Sheliak's variations, easily visible to the naked eye by
comparing the star to others in the constellation, were discovered in 1784. Such eclipsing
doubles (the most famous Algol in Perseus) tell astronomers a great deal about stars,
helping to determine their masses and diameters. Eclipsers are actually quite common,
but again Sheliak is different.
The two stars, both quite massive, are very close together. Tidal forces both distort the
stars and cause streams of matter to flow from one star to the other and apparently in a
disk around the fainter of the two, making the pair both quite difficult and not very well
understood. Such "mass transfer" is profoundly important in the lives of double stars and
produces some of the more bizarre of celestial phenomena (including Sheliak!). In
extreme cases, one star can actually orbit inside the extended envelope of an expanding,
dying giant star, gradually bringing the two closer together and setting the stage for later
stellar explosions. Others are so close they actually touch at their surfaces.
Observations:
C8 at 65x. Some observers see W and pG; Webb saw them as Y and W. However,
there is much disagreement historically on the colors.
Rich field.
C-11 at 115x. Very nice system!

NGC 6720
Rating: 1 E
Other Names: Ring Nebula; PK 63+13.1, M57
Astronomical Leage Program: Messier Club, Urban Deep Sky Club
Position: 1854+3302
Type: Pn
Dimensions: 80" x 60"
Class: 4
Magnitude: 8.8
Notes:
It was discovered by Darguier in 1779 while observing the Comet of 1779 and wrote
that it "is very dull but perfectly outlined; it is as large as Jupiter and resembles a fading
Planet."
Messier added it to his list on January 31, 1779, thinking it was an unresolved cluster.
It is 1 light year in diameter. The central star has a surface temperature of 100,000o
K, but not visible to an 8" scope.
The ring is expanding at 12 mps, implying an age of 20,000 years.
Presently, over 1,000 planetary nebulae are known to exist in the Milky Way, and
possibly as many as 10,000 altogether (many of which will never be seen from Earth).
For years, it was thought that planetary nebulae were, by and large, spherical shells of
ejected star stuff blown off by an aging star. Recent discoveries, mainly with the Hubble
Space Telescope, have lead us to think differently. It is now believed that as a star ages,
its fate depends largely on its mass. In the case of sun-like stars, planetary nebulae are
often formed. Larger stars undergo mass loss through high-speed stellar winds (one
wants to say "starcanes"); even larger stars become supernovae.
The planetary nebula phase of a star’s evolution only lasts about 25,000 to 50,000
years (out of a lifetime of 5 to 10 billion years), so they should be (and are) rather rare.
They are formed by red giants that are burning hydrogen in a shell around a growing
nucleus of helium "ash". We now think that due to magnetic fields, this ejected material
is blown out in a tube shape. When we happen to lie along the tube’s major axis (as we
do with M57), we see a ring. If we are off the axis a few degrees, we see double rings (as
in the Helix Nebula, NGC 6543, or the "eyes" of the Owl Nebula, M97). If we are
perpendicular to the axis, we might see a shape like the Box Nebula or the Dumbbell
Nebula.
