HAT-P-8. Bergfors et al. (2013) estimate spectral types F5-F8V and
M1-M3.5V.
Brg2013
BEC 2
BC: Bechter et al. (2014) resolved the 1" companion to HAT-P-8 into 2
stars, separated by 65 mas. Both components appear to be physically
associated with the primary. Spectral types of the B and C components
are ~M5V and ~M6V; masses are 0.22 +/- 0.03 and 0.18 +/- 0.02 Msun.
