STF1820 |
Two possible solutions by Kiyaeva et al. (1998), based on a 26-year |
Kiy1998 |
|
long series of photographic data from Pulkovo. |
|
|
A component is SB1 (P=2.87 yr, e=0.75). Spectral types and |
|
|
magnitudes are estimated for all components of this triple system. |
|
|
A: Ren & Fu (2013) calculated an astrometric orbit, combining |
|
|
Hipparcos Intermediate Astrometric Data with spectroscopic elements by |
|
|
Kiyaeva et al. (1998). They derived component masses 0.84 and 0.52 |
Kiy1998 |
|
Msun and an estimated semimajor axis of 57.65 mas. |
