de Wit et al. 2024: 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, A. Ruiz, N. Britavskiy, E. Christodoulou, K. De, G. Maravelias, G. Munoz-Sanchez, A. Tsopela 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 …

Antoniadis et al. 2024: Establishing a mass-loss rate relation for red supergiants in the Large Magellanic Cloud

K. Antoniadis, A.Z. Bonanos, S. de Wit, E. Zapartas, G. Munoz-Sanchez, G. Maravelias High mass-loss rates of red supergiants (RSGs) drastically affect their evolution and final fate, yet their mass-loss mechanism remains poorly understood. Various empirical prescriptions scaled with luminosity have been derived in the literature, yielding results with a …

Observing time granted in both ESO/VLT and GTC

Our successful record of observing proposal continues also in 2024! We managed to obtain highly competitive observing time in two of the largest facilities in the world. We are going to use the FORS2 instrument at 8.2m ESO/VLT, as well as OSIRIS at 10.4m GTC. The granted time is ~17.5 …
