Binary and Multiple O‐Type Stars in the Cassiopeia OB6 Association
Binary and Multiple O‐Type Stars in the Cassiopeia OB6 Association
We present the results of time-resolved spectroscopy of 13 O-type stars in the Cas OB6 stellar association. We conducted a survey for radial velocity variability in search of binary systems, which are expected to be plentiful in young OB associations. Here we report the discovery of two new single-lined binaries, …
