Barnard's Star
Position: 1758+0439
Rating: 5 E
Type: Dwarf
Notes:
Only 1/2500th as bright as the Sun, it has only 16% of its mass, and only 20% of its
size, but 40 times its density.
Its surface temperature is 3,200o K, and it seems to have a massive companion with
about 1.5 times the mass of Jupiter.
Its proper motion is a whopping 10.29" per year @ 356. (This translates to 1o of
displacement per 351 years.) Its actual velocity works out to 103 miles per second.
Proper motion was discovered in 1718 by Edmund Halley (of the comet fame).
Several other high proper motion stars are known, such as UV Cet, Lalande 21185
(UMa), Wolf 359 (Leo), Ross 614 (Mon), Piazzi’s Flying Star (61 Cyg), Groombridge
1830 (UMa), Kapteyn’s Star (Pic), and Van Biesbroeck’s Star (Aql). If one scans a list
of the 33 highest proper motion stars known, one finds that the overwhelming majority of
them are dwarfs of spectral classes K and M, with a light sprinkling of G’s. Since high
proper motion stars imply close proximity to the Sun, it thus makes sense that most of
these "movers and shakers" are dwarfs since by default dwarfs become undetectable at
greater distances and most of the stars we see in the sky are brighter and farther stars. In
other words, the survey of high proper motion stars shows us what the galactic "local
neighborhood" really looks like, and it is not what our eyes at first suggest to us. We
look into the sky with our telescopes and think we must live in a very congested suburb,
but the truth is our region of the Galaxy is fairly sparsely populated with mostly dwarfs.

In fact, probably 90% of all stars in the Universe are dwarfs like these. As it turns out,
we live in a very typical, very hum-drum neighborhood!

Notes:
1829: 0.6 @ 147. Over 100 measurements. The orbital period is 46.08 years
(Wilson, 1976) with semi-major axis of 0.98" and retrograde motion in a highly-inclined
orbit. The primary is also a spectroscopic binary, and the entire system is part of the Zeta
Her group.
Observations:
C8 at 697x Webb saw them as Y! and D.

Diameter: A = 2.85 inches; B = 13.2 inches.
Separation: AB = 264 feet.

NGC 6402
Other Names: M14
Astronomical Leage Program: Messier Club
Rating: 3 E
Position: 1738-0315
Type: Gc
Dimensions: 6'
Class: 8
Magnitude: 9.0
Notes:
Messier discovered in it on June 1, 1764, describing it as a "nebula without star."
It is 155 light years in diameter. The brightest stars are 14.0m and the horizontal
branch is 17.2m.
Absorption in this area runs about 2.9m.
Observations:
C8 at 206x. Large, bright and semi-resolved at high power.
C11 at 98x. Very large and semi-resolved, and rather uniform in brightness. Not
much of a core. Class: 10.
Model (where the Sun is a baseball):
Its diameter would be 25,280 miles.
Distance (LY): 45,000
Luminosity (suns): 400,000
