WDS 01418+4237 MCY 2 : NOTES
 
 
discov_num notes refcode
MCY 2 An astrometric binary now resolved by infrared speckle interferometry.
Discovery designation per Todd Henry 03/02/98.
Improved pc (Delta m > 6) orbit combining pg (Lippincott 1983) and Lip1983
Hipparcos obs. Scaling by the speckle IR (Henry 1993) gives orbit size Hen1993
and mass ratio.
Martin et al. (1998) derive component masses 0.795 +/- 0.159 and
0.136 +/- 0.053 Msun. Mig1998
The estimated magnitude difference in V (~6 mag) is too large for the
companion to have been detected. Hrt2009
Mass of A(B) determined to be 0.95+/-0.11(0.254+/-0.019) \msun. Orbital
parallax 79.08 +/- 0.63 mas. Trr2022
