First spectroscopic identification of the main sequence in Westerlund 1
R. Castellanos, F. Najarro, M. Garcia +8
Being the most massive known young stellar cluster in the Milky Way, Westerlund 1 (Wd1) constitutes an ideal benchmark for understanding the evolution of massive stars. However, th…
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 third red supergiant rich cluster in the Scutum-Crux Arm
J. S. Clark, I. Negueruela, B. Davies +6
We aim to characterise the properties of a third massive, red supergiant dominated galactic cluster. To accomplish this we utilised a combination of near/mid-IR photometry and spec…
