VdBH 222: a starburst cluster in the inner Milky Way [PDF]
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-wavelength observations.Methods.We obtained multi-band optical (UBVR) and

Clusters rich in red supergiants [PDF]
AbstractIn the past few years, several clusters containing large numbers of red supergiants have been discovered. These clusters are amongst the most massive young clusters known in the Milky Way, with stellar masses reaching a few 104M⊙. They have provided us, for the first time, with large homogeneous samples of red supergiants of a given age.

The Blue Supergiant Problem and the Main-Sequence Width
Using Gaia DR3 we derive new distances and luminosities for a sample of Galactic B supergiants which were thought to be post main-sequence (MS) objects from their HR diagram location beyond the terminal-age MS (TAMS).

Type IIP supernovae (SNe IIP) mark the explosive death of red supergiants (RSGs), evolved massive stars with an extended hydrogen envelope. They are the most common supernova type and allow for the benchmarking of supernova explosion models by ...

The MACHO Project 9 Million Star Color-Magnitude Diagram of the Large Magellanic Cloud [PDF]
We present a 9 million star color-magnitude diagram (9M CMD) of the LMC bar. The 9M CMD reveals a complex superposition of different age and metallicity stellar populations, with important stellar evolutionary phases occurring over 3 orders of magnitude ...

Analysis of Red Supergiants in VDBH 222
Abstract Recent surveys uncovered new young massive clusters (YMCs) that host dozens of red supergiants (RSGs) in the inner Milky Way. These clusters are ideal for studying the most recent and violent star formation events in the inner Galaxy.

We examine the spatial distributions of luminous blue variables (LBVs), B [ e ] supergiants, and Wolf–Rayet stars (WR) stars in the Large Magellanic Cloud (LMC) to clarify their relative ages, evolutionary states, and relationships. This survey employs a

Red Supergiants in the Milky Way and Nearby Galaxies
Identifications of red supergiants (RSGs) in the Milky Way and nearby galaxies have experienced an exponential increase in recent years, driven by advancements in selection techniques, the continued expansion of archival datasets, and a steady increase ...

<3D> NLTE line formation in the atmospheres of red supergiants
Red supergiants with their enormous brightness at J-band are ideal probes of cosmic chemical composition. It is therefore crucial to have realistic models of radiative transfer in their atmospheres, which will permit determination of abundances accurate ...
