Context. Several clusters of red supergiants have been discovered in a small region of the Milky Way close to the base of the ScutumCrux Arm and the tip of the Long Bar. Population synthesis models indicate that they must be very massive to harbour so many supergiants. Amongst these clusters, Stephenson 2, with a core grouping of 26 red supergiants, is a strong candidate to be the most massive young cluster in the Galaxy. Aims. Stephenson 2 is located close to a region where a strong over… Expand
VdBH 222: a starburst cluster in the inner Milky Way
Context. It has been suggested that the compact open cluster VdBH 222 is a young massive distant object. Aims. We set out to characterise VdBH 222 using a comprehensive set of multi-wavelengthExpand
The population of M-type supergiants in the starburst cluster Stephenson 2
The open cluster Stephenson 2 contains the largest collection of red supergiants known in the Galaxy, and at present is the second most massive young cluster known in the Milky Way. We have obtainedExpand
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
A new survey of cool supergiants in the Magellanic Clouds
In this study, we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of the brightnessExpand
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
NGC 7419 as a template for red supergiant clusters
Context. The open cluster NGC 7419 is known to contain five red supergiants and a very high number of Be stars. However, there are conflicting reports about its age and distance that prevent a usefulExpand
Identification of red supergiants in nearby galaxies with mid-IR photometry
Context. The role of episodic mass loss in massive-star evolution is one of the most important open questions of current stellar evolution theory. Episodic mass loss produces dust and thereforeExpand
The initial masses of the red supergiant progenitors to Type II supernovae
There are a growing number of nearby SNe for which the progenitor star is detected in archival pre-explosion imaging. From these images it is possible to measure the progenitor's brightness a fewExpand
Identification of dusty massive stars in star-forming dwarf irregular galaxies in the Local Group with mid-IR photometry
Increasing the statistics of spectroscopically confirmed evolved massive stars in the Local Group enables the investigation of the mass loss phenomena that occur in these stars in the late stages ofExpand
HIGHLIGHTS OF COMMISSION 37 SCIENCE RESULTS
Abstract It is widely accepted that stars do not form in isolation but result from the fragmentation of molecular clouds, which in turn leads to star cluster formation. Over time, clusters dissolveExpand
