A massive association around the obscured open cluster RSGC3

  title={A massive association around the obscured open cluster RSGC3},
  author={I. Negueruela and Carlos Gonzalez-Fernandez and Amparo Marco and J. Simon Clark},
  journal={Astronomy and Astrophysics},
Context. Four clusters of red supergiants have been discovered in a region of the Milky Way close to base of the Scutum-Crux Arm and the tip of the Long Bar. Population synthesis models indicate that they must be very massive to harbour so many supergiants. If the clusters are physically connected, this Scutum Complex would be the largest and most massive star-forming region ever identified in the Milky Way. Aims. The spatial extent of one of these clusters, RSGC3, has not been investigated. In… Expand

The main sequence of three red supergiant clusters
Massive clusters in our Galaxy are an ideal testbed to investigate the properties and evolution of high-mass stars. They provide statistically significant samples of massive stars of uniform ages. ToExpand
Masgomas-4: Physical characterization of a double-core obscured cluster with a massive and very young stellar population
Context. The discovery of new, obscured massive star clusters has changed our understanding of the Milky Way star-forming activity from a passive to a very active star-forming machine. The search forExpand
A massive open cluster hiding in full sight
Obscuration and confusion conspire to limit our knowledge of the inner Milky Way. Even at moderate distances, the identification of stellar systems becomes compounded by the extremely high density ofExpand
Identifying two groups of massive stars aligned in the l ~ 38° Galactic direction
Context. Recent near-infrared data have contributed to unveiling massive and obscured stellar populations in both new and previously known clusters in our Galaxy. These discoveries have lead us toExpand
Stellar population astrophysics (SPA) with the TNG

A long-period Cepheid variable in the starburst cluster VdBH222
Context. Galactic starburst clusters play a twin role in astrophysics, serving as laboratories for the study of stellar physics and also delineating the structure and recent star formation history ofExpand
GIANO-TNG spectroscopy of red supergiants in the young star cluster RSGC3

The population of OB supergiants in the starburst cluster Westerlund 1
Context. After leaving the main sequence, massive stars undergo complex evolution, a process that is still poorly understood. With a population of hundreds of OB stars, the starburst clusterExpand
