A Common Proper-motion Companion to the Herbig Be Star HD 259431.

VAN DEN ANCKER M.

Abstract (from CDS):

We report on new measurements with the SPHERE instrument on the VLT of a companion 3.″117 N (PA = 345.°3) of the Herbig Be star HD 259431 (MWC 147). Comparison with previous literature measurements shows the companion to have a common proper motion with HD 259431. It is likely a 1.2 M⊙ young star surrounded by a disk.
