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
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


Another cluster of red supergiants close to RSGC1
Context. Recent studies have revealed massive star clusters in a region of the Milky Way close to the tip of the Long Bar. These clusters are heavily obscured and are characterised by a population ofExpand
A massive association around the obscured open cluster RSGC3
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 thatExpand
A Massive Cluster of Red Supergiants at the Base of the Scutum-Crux Arm
We report on the unprecedented red supergiant (RSG) population of a massive young cluster, located at the base of the Scutum-Crux Galactic arm. We identify candidate cluster RSGs based on 2MASSExpand
A third red supergiant rich cluster in the Scutum-Crux arm
Aims. We aim to characterise the properties of a third massive, red supergiant dominated galactic cluster. Methods. To accomplish this we utilised a combination of near/mid- IR photometry andExpand
An obscured cluster associated with the H II region RCW173
Context. The discovery of several clusters of red supergiants towards l = 24 ◦ −30 ◦ has triggered interest in this area of the Galactic plane, where lines of sight are very complex and previousExpand
Discovery of an extraordinarily massive cluster of red supergiants
We report the discovery of an extraordinarily massive young cluster of stars in the Galaxy, having an inferred total initial cluster mass comparable to the most massive young clusters in the Galaxy.Expand
