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 |
|
See also HST observations and discussion of all components of this |
|
|
multiple system by Soderblom et al. (1998). |
