discov_num notes refcode
STI2051 A is an astrometric binary. B (mag. 12.44, 8", DC) is a white dwarf,
in slow retrograde motion about the mass-center. A very large proper
proper motion brought this pair close to a 13th magnitude star which
was measured as the C component by Pauwels & Lampens. Pws1993
Also known as HDS 584.
B: Teff = 7122 +/- 122 K, R = 0.0114 +/- 0.0004 \rsun, M = 0.675 +/- BdH2017b
0.051 \msun.
AB: Rectilinear solutions by Cvetkovic (2015) Cve2015b
and Cvetkovic et al. (2016). Cve2016
Despite the linear solution, based on proper motion and parallax
is physical.
