discov_num notes refcode
FIN 368 Aa,Ab: Hipparcos parallax 13.56 +/- 0.76 mas. Dynamical parallax 13.3
mas, masses 1.79 and 1.23 Msun. Speckle measures of 1989-91 and McA1990
2009-11 repeat themselves, hinting at a 20 yr period. However, the Tok2010
measure by Mason et al. in 2006.2 does not fall on the same ellipse Msn2009
and had to be ignored. It could refer to another star, as FIN 368
should have been unresolved at that time according to our preliminary
orbit, which also matches the speckle non-resolution in 1976.3 and the
non-resolutions in 1964-1966 by Finsen. An alternative orbit with P = Fin1965a
10.13 yr and e = 0.9 can also be fitted to the data. The Hipparcos
measure on 1991.25 contradicts speckle interferometry on 1991.39; it HIP1997a
had to be ignored. Nordstrom et al. (1997) noted double lines Nrd1997
broadened by fast axial rotation of 100 km/s and 20 km/s. However,
individual RVs measured by these authors during 1987-1991 (near the
apastron) do not show any systematic behavior that could be related to
the orbit. Continued speckle monitoring will be critical for
confirming the orbit.
