Massive stars play a major role in the evolution of their host galaxies and serve as important
probes of the distant Universe. It has been established that the majority of massive stars …

We conduct a rigorous examination of the nearby red supergiant Betelgeuse by drawing on
the synthesis of new observational data and three different modeling techniques. Our …

The evolved stages of massive stars are poorly understood, but invaluable constraints can
be derived from spatially resolved observations of nearby red supergiants, such as …

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 …

We investigate the influence of magnetic field amplification on the core-collapse supernovae
in highly magnetized progenitors through 3D simulations. By considering rotating models …

We investigate the merger between a 16M⊙ star, on its way to becoming a red supergiant
(RSG), and a 4M⊙ main-sequence companion. Our study employs three-dimensional …

After core hydrogen burning, massive stars evolve from blue-white dwarfs to red supergiants
by expanding, brightening, and cooling within few millennia. We discuss a previously …

We study the effects of the magnetic field on the dynamics of non-rotating stellar cores by
performing 2D, magnetohydrodynamic (MHD) simulations. To this end, we have updated our …

Recent work measuring the binary fraction of evolved red supergiants (RSGs) in the
Magellanic Clouds points to a value between 15% and 30%, with the majority of the …

Context. The features in the light curves and spectra of many Type I and Type II supernovae
(SNe) can be understood by assuming an interaction of the SN ejecta with circumstellar …
