The massive triple star system HD 16429 A.
McSWAIN M.V.
Abstract (from CDS):
HD 16429 A is a triple star system consisting of a single-lined spectroscopic binary and a widely separated third component, previously identified via speckle interferometry. Here I present the first orbital elements for the unblended spectroscopic binary as well as estimates of the spectral types and relative flux contributions for each visible component based on a Doppler tomographic reconstruction of their spectra. There are several stars around HD 16429 A, including the nearby Be X-ray binary and microquasar LS I +61°303, which all probably belong to a subcluster within the Cas OB6 association.
