Evolved Massive Stars at Low Metallicity. VI. Mass-loss Rate of Red Supergiant Stars in the Large Magellanic Cloud

The Astronomical Journal
Mass loss is a crucial process that affects the observational properties, evolution path, and fate of highly evolved stars. However, the mechanism of mass loss is still unclear, and the mass-loss rate (MLR) of red supergiant stars (RSGs) requires further

Magnetic fields around evolved stars [Elektronisk resurs]

, 2018
There has long been evidence of magnetic fields in the extended envelopes of asymptotic giant branch (AGB) and red supergiant (RSG) stars. These stars are important contributors to the enrichment of the interstellar medium by dust and heavy elements ...

Implications of Modern Mass-loss Rates for Massive Stars

The Astrophysical Journal
Massive stars lose a significant fraction of their mass through stellar winds at various stages of their lives, including on the main sequence, during the red supergiant (RSG) phase, and as helium-rich stripped stars.

On the Spatial Distribution of Luminous Blue Variables, B[e] Supergiants, and Wolf–Rayet Stars in the Large Magellanic Cloud

The Astrophysical Journal
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

Is the RSGC4 (Alicante 8) Cluster a Real Star Cluster? Peculiar Radial Velocities of Red Supergiant Stars

The Astronomical Journal
Young massive star clusters, like the six red supergiant clusters in the Scutum complex, provide valuable insights into star formation and galaxy structures. We investigated the high-resolution near-infrared spectra of 60 RSG candidates in these clusters
