discov_num notes refcode
HO 286 Often seen single. Rapid binary, distances small and quadrants
uncertain. One component is a Cepheid, V1334 Cyg.
CIA 5 Aa,Ab: Gallenne et al. (2013) resolved the primary into an 8,as pair,
and derived a combined spectroscopic/interferometric orbit. Spectral
type of the companion is earlier than B5.5V. CIA2013a
Masses are 4.9 and 4.0 Msun. Estimated period = 5.3y,
a = 6.3au = 0.01". Evs2013
Limb darkened diameter of Cepheid = 0.524 +/- 0.039 mas.
Limb darkened diameter of Cepheid = 40.6 +/- 3.0 \rsun.
Mass of A,B = 4.288 +/- 0.133, 4.040 +/- 0.048 \msun.
Mass of secondary = 4.288 +/- 0.133 \msun. GaA2018
Mass of A,B = 4.6 +/- 0.7. 3.80 +/- 0.57 /msun. Krv2019a
