Investigating the properties of Galactic Luminous Blue Variables via IR observations
J. S. Clark, A. Arkharov, V. Larionov +3
Recent IR surveys of the Galactic plane have revealed a large number of candidate Luminous Blue Variables. In order to verify these classifications we have been undertaking a long…
The massive binary population of the starburst cluster Westerlund 1
B. W. Ritchie, J. S. Clark, I. Negueruela
We present initial results from a long-baseline radial velocity survey for massive binaries in the cluster Westerlund 1. Four systems are examined: the dust-producing WC binary W23…
A VLT/FLAMES survey for massive binaries in Westerlund 1: II. Dynamical constraints on magnetar progenitor masses from the eclipsing binary W13
B. W. Ritchie, J. S. Clark, I. Negueruela +1
Westerlund 1 is a young, massive Galactic starburst cluster that contains a rich coeval population of Wolf-Rayet stars, hot- and cool-phase transitional supergiants, and a magnetar…
The population of OB supergiants in the starburst cluster Westerlund 1
Ignacio Negueruela, J. Simon Clark, Ben W. Ritchie
After leaving the main sequence, massive stars undergo complex evolution, still poorly understood. With a population of 100s OB stars, the starburst cluster Westerlund~1 offers an…
A serendipitous survey for variability amongst the massive stellar population of Westerlund 1
J. S. Clark, B. W. Ritchie, I. Negueruela
Massive stars exhibit spectroscopic and photometric variability over a wide range of timescales. However the physical mechanisms driving this behaviour remain poorly understood. We…
