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

S. de Wit, G. Muñoz-Sanchez, G. Maravelias, A.Z. Bonanos, K. Antoniadis, D. García-Álvarez, N. Britavskiy, A. Ruiz, A. Philippopoulou Mass loss in massive stars is crucial to understanding how these stars evolve and explode. Despite increasing evidence indicating its importance, episodic mass loss remains poorly understood. Here we report the …
