STF1110 alp Gem = 66 Gem = Castor. STFB 4. According to R.G. Aitken, this was A__1935f
discovered in 1719 by Bradley and Pound. Mt. Wilson spectral types Bdy1832A
A2,A2,M1. A and B are both SB1's with P = 9.21 d and 2.93 d. Pnd1832A
Castor A is also reported to exhibit x-ray and radio emission.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Star C (mag. 9.1, M1Ve) is the spectroscopic and detached eclipsing
binary YY Gem (P = 0.81 d), 70" from the center of AB and in slow
retrograde motion (cf., Heintz), so the object is sextuple. Hei1960a
AB: H 2 1. MEv2010
AB: Additional notes may be found in Fu et al. (1997) McA1997
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 5.43 +/- 0.97, 4.27, and 4.28 Msun, respectively. Mlk2012
Components Aa, Ab, Ba and Bb determined to have masses of 2.74+/-0.11, Ana2015
0.37+/-0.09, 2.26+/-0.10 and 0.53+/-0.09 \Msun, respectively.
Aa,Ba MYSTIC uniform disk dia. = 1.271 +/- 0.012, 0.994 +/- 0.014 mas.
Aa,Ba MIRC-X uniform disk dia. = 1.273 +/- 0.003, 1.005 +/- 0.008 mas.
Aa,Ab masses = 2.371 +/- 0.015, 0.3859+/- 0.0018 \msun.
Ba,Bb masses = 1.789 +/- 0.016, 0.3865+/- 0.0020 \msun. CIA2022d
Many historic AB measures corrected and missing measures added. CIA2022d
