[ 1] Eta Gem. A is a semi-regular variable. A premature
visual orbit has been computed. A is also an occulta-
tion binary and a long-period spectroscopic binary.
[ 2] H V 55.
[ 3] A is a spectroscopic binary, P = 6.99d. It is also one
of the brightest BY Dra-type variables known, OU Gem.
[ 4] Same as CHE 82.
[ 5] B is BD+20@1426.
[ 6] A is a spectroscopic binary.
[ 7] BDS 3424 probably same star. Spectrum of B: F6IV/V.
The A component is an occultation double.
[ 8] AB: B is BD+12@1221.
[ 9] 25 Gem.
[ 10] 30 Gem.
[ 11] 38 Gem. A is a Delta Scuti-type variable.
A premature orbit has been computed for AB.
[ 12] 45 Gem. B and C are optical.
[ 13] Tau Gem. A is an irregular variable.
[ 14] Lambda Gem. A is a spectroscopic and occultation
binary, and may be variable.
[ 15] Delta Gem. A premature orbit has been computed. A is an
occultation double, and a long-period spectroscopic
binary. Also known as CHE 85.
Coordinates and proper motions from ACRS, PPM, IRS,
FK5 catalogs.
[ 16] Spectroscopic binary. Spectrum: K0II-III+F8V.
[ 17] Alpha Gem. Castor. Mt. Wilson spectral types A2,A2,M1.
P = 467yr., a = 6.80", motion retrograde. A and B are
both spectroscopic binaries, and C is the eclipsing
binary YY Gem, P =0.81d, so the object is sextuple.
Castor A is also reported to exhibit x-ray and radio
emission.
[ 18] Kappa Gem.
[ 19] Pi Gem. Variable?
