WDS 09173-6841 FIN 363 AB : NOTES
 
 
discov_num notes refcode
FIN 363 Speckle observations needed to refine relative orbit.
AB: Hipparcos parallax 30.64 +/- 0.70 mas. Dynamical parallax 27.2 mas,
masses 1.63 and 1.37 Msun. FIN 363 has an unusually short period of
only 3.44 yr. The Hipparcos photometry is doubtful because of close
0.1" separation. Tok2012b
AB: Martin et al. (1998) derive component masses 3.661 +/- 0.338 and
3.661 +/- 0.338 Msun. Mig1998
AB: Docobo & Andrade (2013) derive a dynamical parallax of 29.71 +/-
1.33 mas and component masses 1.43 +/- 0.25 and 1.06 +/- 0.20 Msun.
See paper for extensive notes on this system. Doc2013d
