Titolo: M dwarf stars: a thorny problem of stellar evolution… but also a big opportunity…

Abstract:

M dwarfs are becoming extremely important targets in the search of exo-planets with Earth-like
characteristics, and as a consequence there is a strong, renewed intest toward this peculiar class
of stars.
From the point of view of stellar physics, M dwarfs are extremely intriguing objects
due to the peculiar thermal conditions experienced by their interiors and outer layers.
For long time, an accurate modelling of these structures has been hampered by the lack of
reliable predictions about the input physics to be used in the stellar model computations,
as well as about how to account for the various physical processes affecting these stars.
In this seminar we’ll review the Physics of M dwarf stars, and the improvements obtained in these
last years, and we’ll also discuss some open issues related to the modelling of these stars.
