discov_num notes refcode
HDS2143 The composite spectrum of this pair is given in the SIMBAD database as
a K0III, and we derive a magnitude difference of approximately 2.5,
which is slightly higher at bluer wavelengths. This suggests that
while the primary is evolved, the secondary is still near the main
sequence, and so a study could be done along the lines of Davidson et Hor2009b
al. (2009) to determine the age and individual masses of the two stars
from the photometry through isochrone fitting. Also, the orbit we
calculate has very high eccentricity, which helps explain why there
were no successful observations of the pair in the late 1990s:
periastron passage was in 1997, with predicted separation of 6 mas. Hor2015b
