discov_num notes refcode
B 719 VY CMa. This multiple "star" is involved in nebulosity, shaped like
the tail of a comet. All companions may be knots in the nebulosity,
and all may seem variable.
Adaptive optics imaging by Shenoy et al. (2013) in Ks, L', and M bands
suggest the brightness of the "Southwest Clump" (~1.5" from central
star) is almost entirely due to scattering from silicate dust grains.
Lower mass limit for this feature is 5 x 10^-3 to 2.5 x 10^-2 Msun,
depending on assumed gas-to-dust ratio. Presence of clump with no
apparent counterpart on other side of star suggests ejection event. SDP2013
