New paper: de Wit et al. 2025: Investigating episodic mass loss in evolved massive stars: III. Spectroscopy of dusty massive stars in three northern galaxies

This is the complementary work to that of Alceste’s published some time ago, covering the southern galaxies. Now it was Stephan and Gonzalo’s turn to lead this the paper for the northern galaxies, observed with the 10.4 m GTC. We managed to classify 122 additional sources, increasing the number of …

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 …
