GRE 3 Aa,Ab: IRAS 11195-2430 = PDS 54. Gre1992
I 507 Variable TV Crt. Tokovinin (1999) gives three possible orbits which Tok1999b
are consistent with visual and IR speckle observations, as well as
radial velocity difference and Hipparcos parallax for stars of this
type (K5V). Inclination is near 90 degrees, but eccentricity is not
high, as predicted by Torres et al. (1995). Trr1995b
Star has large IR excess. A component is SB1 (P=262 days), while B
component is SB2 (P=315 days). Tok1999b
Torres et al. (1995) report radial velocity data and make some
constraints on possible astrometric orbits. Trr1995b

multiple system by Soderblom et al. (1998). Sdb1998
