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

Finally…after some years from the initial paper on the method I managed to put everything together to publish the second part of the machine-learning classifier for massive stars in nearby galaxies. This work is actually the application of the classifier to the whole sample of 26 galaxies and about 1.1 …

New paper: de Wit et al. 2024: Investigating episodic mass loss in evolved massive stars: II. Physical properties of red supergiants at subsolar metallicity

Stephan extends the work he has performed previously in the Magellanic Clouds to RSGs identified in the ASSESS project in galaxies at subsolar metallicity. 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, E. Zapartas, …

New paper: Using machine learning to investigate the populations of dusty evolved stars in various metallicities

This is actually a preview of what will follow after the first paper of the machine-learning classifier. We put it into action to get predictions for a number of galaxies and we start exploring the results. Of more interest is the fractions of the populations with metallicity, although a more …
