Constraining the z ∼ 1 Initial Mass Function with HST and JWST Lensed Stars in MACS J0416.1−2403

The Astrophysical Journal
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date the IMF is constrained only to local galaxies.

Red Supergiants as Supernova Progenitors

Galaxies
The inevitable fate of massive stars in the initial mass range of ≈8–30M⊙ in the red supergiant (RSG) phase is a core-collapse supernova (SN) explosion, although some stars may collapse directly to a black hole.

Is Betelgeuse Really Rotating? Synthetic ALMA Observations of Large-scale Convection in 3D Simulations of Red Supergiants

The Astrophysical Journal Letters
The evolved stages of massive stars are poorly understood, but invaluable constraints can be derived from spatially resolved observations of nearby red supergiants, such as Betelgeuse.

Red Supergiant Mass Loss and Mass-Loss Rates

Galaxies
This review discusses the causes, nature, importance and observational evidence of mass loss by red supergiants. It arrives at the perception that mass loss finds its origin in the gravity which makes the star a star in the first place, and is a ...

A comprehensive grid of massive binary evolution models for the Galaxy: Surface properties of post-mass-transfer stars

Astronomy & Astrophysics
Context. Massive stars often evolve in binary systems, and the interactions of these systems significantly affect their evolution. Massive stars in the Galaxy serve as valuable test beds for such interactions due to their proximity. Aims. We computed the

A Comprehensive Catalog of Emission-line Nebulae, Star Clusters, and Supergiants in M31 from the LAMOST Spectroscopic Survey

The Astronomical Journal
Spectroscopic observations of various tracers in nearby galaxies, such as Andromeda (M31), play a crucial role in identifying and classifying individual stellar populations and nebular objects, thereby enhancing our understanding of galactic composition,
