The Massive Triple Star System HD 16429 A

Astrophysics 2009-11-07 v1

Abstract

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 upon 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 sub-cluster within the Cas OB6 association.
