Red supergiants are the most common final evolutionary stage of stars that have initial
masses between 8 and 35 times that of the Sun. During this stage, which lasts roughly …

Abstract The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by
the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the …

We outline the impact of a small two-band UV-photometry satellite mission on the field of
stellar physics, magnetospheres of stars, binaries, stellar clusters, interstellar matter, and …

The red hypergiant VY CMa and the more typical red supergiant (RSG) Betelgeuse provide
clear observational evidence for discrete, directed gaseous outflows in their optical and …

BRITE-Constellation is devoted to high-precision optical photometric monitoring of bright
stars, distributed all over the Milky Way, in red and/or blue passbands. Photometry from …

During the core collapse of massive stars that do not undergo a canonical energetic
explosion, some of the hydrogen envelope of a red supergiant (RSG) progenitor may infall …

Context. Despite being the best studied red supergiant star in our Galaxy, the physics
behind the photometric variability and mass loss of Betelgeuse is poorly understood …

Was Betelgeuse once in a binary star system? What causes it to vary over a vast range of
timescales? Why did it dim dramatically in 2020? When and how will it explode? J. Craig …

The processes that shape the extended atmospheres of red supergiants, heat their
chromospheres, create molecular reservoirs, drive mass loss, and create dust remain poorly …

ABSTRACT A significative fraction of all massive stars in the Milky Way move supersonically
through their local interstellar medium (ISM), producing bow shock nebulae by wind-ISM …
