A machine-learning photometric classifier for massive stars in nearby galaxies II. The catalog

G. Maravelias, A. Z. Bonanos, K. Antoniadis +8

Mass loss is a key aspect of stellar evolution, particularly in evolved massive stars, yet episodic mass loss remains poorly understood. To investigate this, we need evolved massiv…

Episodic mass loss in the very luminous red supergiant [W60] B90 in the Large Magellanic Cloud

G. Munoz-Sanchez, S. de Wit, A. Z. Bonanos +6

This study delves into [W60] B90, one of the most luminous and extreme Red Supergiants (RSGs) in the Large Magellanic Cloud (LMC), aiming to search for evidence of episodic mass lo…

Investigating episodic mass loss in evolved massive stars: II. Physical properties of red supergiants at subsolar metallicity

S. de Wit, A. Z. Bonanos, K. Antoniadis +8

Mass loss during the red supergiant (RSG) phase plays a crucial role in the evolution of an intermediate massive star, however, the underlying mechanism remains unknown. We aim to…

Establishing a mass-loss rate relation for red supergiants in the Large Magellanic Cloud

K. Antoniadis, A. Z. Bonanos, S. de Wit +3

The high mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, but their mass-loss mechanism remains poorly understood. Various empirical pre…

Investigating episodic mass loss in evolved massive stars: I. Spectroscopy of dusty massive stars in ten southern galaxies

A. Z. Bonanos, F. Tramper, S. de Wit +7

The ASSESS project aims to determine the role of episodic mass-loss in the evolution of massive stars. As a first step, we construct a catalog of spectroscopically identified dusty…
