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. Ren2013
