HMM 1 Aa,Ab: 4 Leo = omi Leo = Subra
A 1980 observation of 09285+0903 = ome Leo by Weigelt (1983) was Wgt1983
incorrectly attributed to this star (= omi Leo) in earlier editions
of the interferometric catalog and the WDS. This star was then
mistakenly given the discoverer designation WGT 1 as a result.
Hummel et al. (2001) include data from the Mark III, NPOI, and PTI Hmm2001
interferometers. Dates have been converted from Julian to Besselian;
error ellipses have been converted into quoted rho and theta errors.
The Mark III data were taken with baselines of 28.0 and 31.5 meters,
using 500, 550, and 800nm filters. NPOI data were taken using three
baselines from 19 to 38 meters and in 20 channels from 530 to 850nm.
The paper also includes radial velocity data and a combined
spectroscopic/astrometric orbital solution, yielding a distance and
component luminosity and mass information as well.
P = 14.498064 +/- 0.000009 days, T = JD2450629.831 +/- 0.003;
eccentricity assumed zero.
Aa,Ab: Malkov et al. (2012) derive dynamical and spectroscopic
masses 3.59 +/- 1.93 and 7.07 Msun, respectively. Mlk2012
ARI 1 Aa,Ac: Hummel (2003, private communication) says there was no sign of
the ARI component in their Mark III and NPOI observations, which Ari1999
resolved the closer pair HMM 1Aa,Ab. See Hummel et al. (2001). Hmm2001
H 6 76 AB: H VI 76. Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
