discov_num notes refcode
BD-09 3055 SB1. Curvature seen in proper motion components from Hipparcos data,
although period was unknown. Combined spectroscopic/astrometric
solution, based on echelle spectra and Hipparcos intermediate
data (abscissa residuals). Torres derives a parallax of 19.5 +/- Trr2006a
1.8 mas (compared to Hipparcos value of 29.4 +/- 2.7 mas). An
estimated primary mass of 0.73 +/- 0.05 Msunyield a mass of 0.88 +/-
0.05 Msun for the secondary.
TOK 398 HIP 50796 is a single-lined and astrometric binary according to
(Torres 2006), with period 570.98d (1.56yr), K1=20.76 km/s, e=0.611. Trr2006
The Hipparcos parallax corrected for binary motion is 20.6+/-1.9mas.
The spectroscopic secondary companion is over-massive, most likely a
close pair of M-dwarfs. If so, the new speckle companion at 1".66 with
a period on the order of 500yr makes the system quadruple. The speckle
companion might contribute to the IR excess found by Torres. The
system is an X-ray source, and is possibly young. Tok2015c
