Low-metallicity massive single stars with rotation. III. Source of ionization and C-IV emission in I Zw 18
Dorottya Szécsi, Frank Tramper, Brankica Kubátová +5
Chemically homogeneously evolving stars have been proposed to account for several exotic phenomena, including gravitational-wave emissions and gamma-ray bursts. Here we study wheth…
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…
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…
Discovering new B[e] supergiants and candidate Luminous Blue Variables in nearby galaxies
Grigoris Maravelias, Stephan de Wit, Alceste Z. Bonanos +3
Mass loss is one of the key parameters that determine stellar evolution. Despite the progress we have achieved over the last decades we still cannot match the observational derived…
Using machine learning to investigate the populations of dusty evolved stars in various metallicities
Grigoris Maravelias, Alceste Z. Bonanos, Frank Tramper +7
Mass loss is a key property to understand stellar evolution and in particular for low-metallicity environments. Our knowledge has improved dramatically over the last decades both f…
Reconstructing EUV spectrum of star forming regions from millimeter recombination lines of HI, HeI, and HeII
Lena Murchikova, Eric J. Murphy, Dariusz C. Lis +9
The extreme ultraviolet (EUV) spectra of distant star-forming regions cannot be probed directly using either ground- or space-based telescopes due to the high cross-section for int…
