The circumstellar medium around massive stars is strongly impacted by stellar winds, radiation, and explosions. We use numerical…
Direct images of Betelgeuse were obtained over a span of 4 years with the Faint Object Camera on the Hubble Space Telescope…
A significant fraction of massive stars are moving supersonically through the interstellar medium (ISM), either due to disruption…
We present calculations for a magnetised hybrid wind model for Betelegeuse ( Orionis). The model is a direct application of our…
We present the outcome of a highly-sensitive search for magnetic fields on the cool supergiant Betelgeuse. A time-series of six…
Stellar limb-darkening is an important tool for constraining the properties of a stellar atmosphere. We present a novel method…
The dynamics of the surface and inner atmosphere of the red supergiant star Betelgeuse are the subject of numerous high angular…
Context. Aims. We present spatially resolved high-spectral resolution K-band observations of the red supergiant Betelgeuse (α Ori…
The diameter of Betelgeuse (α Orionis) has been measured at a wavelength of 11.15 μm using the Infrared Spatial Interferometer…
We have analyzed Chandra calibration observations of Betelgeuse (α Ori, M2 Iab, mV = 0.58, 131 pc) obtained at the aimpoint…
