Atmospheric Dynamics of Red Supergiant Stars

, 2008
Thanks to their high-peak infrared luminosity, red supergiant (RSG) stars are fundamental tracers of galactic structure, efficiently probing regions of high interstellar extinction. To understand their properties is crucial and impacts a broad segment of Astrophysics.In this thesis, the answer to the principal questions about RSGs is addressed with ...

Mass-loss Rate of Highly Evolved Stars in the Magellanic Clouds

The Astrophysical Journal Supplement Series
Asymptotic giant branch stars (AGBs) and red supergiant stars (RSGs) exhibit significant mass-loss phenomena and are considered important sources of interstellar dust.

Constraints on the Progenitor and Explosion of SN 2024ggi in Harmony with Preexplosion Detection and Hydrodynamic Simulations

The Astrophysical Journal
Supernova (SN) 2024ggi is a nearby Type II SN discovered by the Asteroid Terrestrial-impact Last Alert System, showing early flash-ionization features. The preexplosion images reveal a red supergiant progenitor with an initial mass of 10–17 M _⊙ . In the

A modeling perspective on the diversity of red supergiant stars exploding within circumstellar material

Astronomy & Astrophysics
With the ever faster cadence of untargeted surveys of the sky, the supernova (SN) community will capture a growing number of shock breakouts in red supergiant (RSG) stars in the coming years.

James Webb Space Telescope Observations of the Nearby and Precisely Localized FRB 20250316A: A Potential Near-IR Counterpart and Implications for the Progenitors of Fast Radio Bursts

The Astrophysical Journal Letters
We present deep James Webb Space Telescope near-infrared imaging to search for a quiescent or transient counterpart to FRB 20250316A, which was precisely localized with the CHIME Outriggers array to an area of 11 × 13 pc in the outer regions of NGC 4141 ...

Boil-off of red supergiants: mass loss and type II-P supernovae

The Open Journal of Astrophysics
The mass loss mechanism of red supergiant stars is not well understood, even though it has crucial consequences for their stellar evolution and the appearance of supernovae that occur upon core-collapse.
