STT 341 Triple solution with C (HIP 88639). Primary is 0.88d RS CVn-type
variable or eclipsing binary (V772 Her). Sod1999
Combined visual-spectroscopic orbits by Heintz (1982); the lines were Hei1982b
separated at periastron passage. Star A is an eclipsing SB1, P = 0.88d Hei1982e
(Batten et al. 1979). Bte1979
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.47 +/- 0.51, 2.06, and 2.00 Msun, respectively. Mlk2012
AB: A is SB1E, P=0.870d. AB is SB2, P=20.081y Tok2014d
