We discuss the physics and the evolution of a typical massive star passing through an evolutionary stage similar to that of Betelgeuse. After a brief introduction recalling various observed parameters of Betelgeuse, we discuss the Pre-Main-Sequence phase (PMS), the Main-Sequence (MS) phase, the physics governing the duration of the first crossing of the HR diagram, the red supergiant stage (RSG), the post-red supergiant phases and the final fate of solar metallicity stars with masses between 9…

Is Betelgeuse the Outcome of a Past Merger?
We explore the possibility that the star alpha Orionis (Betelgeuse) is the outcome of a merger that occurred in a low mass ratio (q = M2/M1 = 0.07 - 0.25) binary system some time in the past hundreds
The Betelgeuse Project: constraints from rotation
In order to constrain the evolutionary state of the red supergiant Betelgeuse, we have produced a suite of models with ZAMS masses from 15 to 25 Msun in intervals of 1 Msun including the effects of
Thermodynamics of dust condensation around the dimming Betelgeuse
Betelgeuse is one of the brightest red supergiant (RSG) stars because of its proximity to the Solar system. This makes it important when deducing the features and evolutionary phases of RSG stars.
Betelgeuse Constraints on Coupling between Axion-like Particles and Electrons
Axion-like particles (ALPs) can be produced by thermal processes in a stellar interior, escape from the star and, if sufficiently light, be converted into photons in the external Galactic magnetic
The close circumstellar environment of Betelgeuse - V. Rotation velocity and molecular envelope properties from ALMA
We observed Betelgeuse using ALMA's extended configuration in band 7 (f~340 GHz, {\lambda}~0.88 mm), resulting in a very high angular resolution of 18 mas. Using a solid body rotation model of the
Fundamental properties of core-collapse Supernova and GRB progenitors: predicting the look of massive stars before death
We investigate the fundamental properties of core-collapse Supernova (SN) progenitors from single stars at solar meta llicity. For this purpose, we combine Geneva stellar evolutionary models with
Constraints on Axionlike Particles from a Hard X-Ray Observation of Betelgeuse.
TLDR
The first observation of Betelgeuse in hard x rays is used to perform a novel search for axionlike particles (ALPs) in the Galactic magnetic field, finding no significant excess of events above the expected background.
Algol anomaly or careful observations of its brightness? The values recorded for the magnitude of Algol in the medieval astronomical corpus
The historical evidence from the past two millennia show two problems concerning the star Algol (β Per): First, a critical variation in its brightness from a magnitude m ~ 2 in (1) Ptolemy’s Almagest
Constraining Weakly Interacting Slim Particles with a Massive Star and in the Laboratory
This doctoral thesis is devoted to constraining the allowed parameter space of weakly interacting slim particles (WISPs). WISPs are predicted by many extensions of the Standard Model of Particle

Pulsations driven by partial ionization of hydrogen in the envelope are often considered important for driving winds from red supergiants (RSGs). In particular, it has been suggested by some authors
