Massive stars, at least∼ 10 \sim10 times more massive than the Sun, have two key
properties that make them the main drivers of evolution of star clusters, galaxies, and the …

The theory and numerical modelling of radiation processes and radiative transfer play a key
role in astrophysics: they provide the link between the physical properties of an object and …

Context. The star cluster R136 inside the Large Magellanic Cloud hosts a rich population of
massive stars, including the most massive stars known. The strong stellar winds of these …

We explore the variation in single-star 15–30${M} _ {\odot} $, nonrotating, solar metallicity,
pre-supernova MESA models that is due to changes in the number of isotopes in a fully …

For the first time, the interior and spectroscopic evolution of a massive star is analyzed from
the zero-age main sequence (ZAMS) to the pre-supernova (SN) stage. For this purpose, we …

Aims. We aim to measure the impact of our mass-loss recipe in the evolution of massive
stars at the metallicity of the Small Magellanic Cloud (SMC). Methods. We used the Geneva …

We calculate radiatively driven wind models of main-sequence B stars and provide the wind
mass-loss rates and terminal velocities. The main-sequence mass-loss rate strongly …

Context. For more than two decades, stellar atmosphere codes have been used to derive the
stellar and wind parameters of massive stars. Although they have become a powerful tool …

The study of massive stars in different metallicity environments is a central topic of current
stellar research. The spectral analysis of massive stars requires adequate model …

Context. Massive stars are among the main cosmic engines driving the evolution of star-
forming galaxies. Their powerful ionising radiation and stellar winds inject a large amount of …
