ENG 75 AB: Components share CPM. Spectral type of B component M1V +/- 1. Cvn2007
CHARA Array Limb-darkened diameter 0.494 +/- 0.046 mas, CIA2008c
R = 1.79 +/- 0.17 \rsun.
CVN 17 Aa,Ab: Companion is a probable late-K dwarf. Cvn2006
Chauvin et al. (2011) make a combined astrometric/RV study of the
expoplanet host binary HD 196885, and derive a mass function for the
planet (M_Aa1 sin i) = 2.98 +/- 0.05 Mjup and a mass for the stellar
companion M_Ab = 0.45 +/- 0.01 Msun. (Note: their paper refers to the
700mas pair as AB and the planet as Ab) Cvn2011
