We provide an update for the astrometric solution for the Type II supernova progenitor Betelgeuse using the revised Hipparcos…
A significant fraction of massive stars are moving supersonically through the interstellar medium (ISM), either due to disruption…
Aims. We present one-dimensional aperture synthesis imaging of the red supergiant Betelgeuse (α Ori) with VLTI/AMBER. We…
Context. Mass-loss occurring in red supergiants (RSGs) is a major contributor to the enrichment of the interstellar medium in…
Context. The red supergiant (RSG) Betelgeuse is an irregular variable star. Convection may play an important role in…
Context. Betelgeuse is an M supergiant with a complex and extended atmosphere, which also harbors spots and giant granules at its…
Aims. This paper reports on H-band interferometric observations of Betelgeuse made at the three-telescope interferometer IOTA. We…
Context. Aims. We present spatially resolved high-spectral resolution K-band observations of the red supergiant Betelgeuse (α Ori…
We have constructed a series of nonrotating quasi-hydrostatic evolutionary models for the M2 Iab supergiant Betelgeuse (α Orionis…
Supergiant stars such as Betelgeuse have very extended atmospheres, the properties of which are poorly understood. Alfvén waves…
