MUG 8 Based on astrometry, photometry and H- and K-band spectroscopy,
Mugrauer et al. (2007) conclude that HD 65216 A and B comprise a Mug2007
physical pair. The projected separation is 253 au. The Ba and Bb
(their B and C) components also appear to be co-moving. From narrow-
band photometry of all components, conclude spectral type of Ba is
M7-M8 and that of Bb is L2-L3; masses are 0.089 +/- 0.001 and 0.078
+/- 0.001 Msun for Ba and Bb, assuming a system age of 5 Gyr. Orbital
period of Ba,Bb estimated at 36y. Theta values estimated from their
Figure 6.
Primary is planet host star. Two companions Ba and Bb bound to A
component. Spectral types of Ba and Bb are M6.5-L0 and M7.5-L4,
respectively. Egn2007
