discov_num notes refcode
STF1967 gam CrB = 8 CrB. A is a Delta Scuti-type variable. The RV does not
show a variation. A few discordant measurements seem to have been
caused by scatter from the poor lines, and the double lines reported
from three old Yerkes plates were also found probably spurious on
remeasurement. See Baize & Petit catalog of doubles with variable Baz1989d
component. Measure of 1989.388 made by MAPPIT. This measure had an Han1989
identification error, position error, or misprint in publication, which
has been corrected.
Spectral types and masses of components assigned by ten Brummelaar et
al., based on adaptive optics observations. TtB2000
Calculated mass sum is 3.73 +/- 0.37 Msun, a bit low for a pair of
early A stars. Mut2010b
Additional notes may be found in Duner (1876). Du_1876
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 4.18 +/- 0.30, 4.34, and 4.57 Msun, respectively. Mlk2012
