WDS 21147-0050 LYS 39 AH : NOTES
 
 
discov_num notes refcode
A 883 AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 21.20 +/- 18.02, 6.44, 2.19 Msun, respectively. Mlk2012
STF2775 AB,C: Star C (mag. 10.52, 21") is probably physical.
Egbert observed a wide new pair (1879.656, 59.9deg, 99".40, mags 9.0 Egb1879
and 9.5), but listed only a coarse epoch-1880 RA and no other
identifier other than his initials. Since his RA matched that of
STF2775, the pair was catalogued as STF2775PQ. There appears to be
nothing in the field of STF2775 which matches this pair, however, so
it has been removed from the WDS.
