Mass loss is a key process in the evolution of massive stars, and must be understood
quantitatively if it is to be successfully included in broader astrophysical applications such as …

Non-degenerate stars of essentially all spectral classes are soft X-ray sources. Their X-ray
spectra have been important in constraining physical processes that heat plasma in stellar …

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 …

Context. Massive binaries hosting a black hole (OB+ BH) represent a critical phase in the
production of BH mergers in the context of binary evolution. In spite of this, such systems …

We computed a comprehensive set of theoretical ultraviolet spectra of hot, massive stars
with the radiation-hydrodynamics code WM-Basic. This model atmosphere and spectral …

Binaries are excellent astrophysical laboratories that provide us with direct measurements of
fundamental stellar parameters. Compared to single isolated stars, multiplicity induces new …

Context. B supergiants (BSGs) are evolved stars with effective temperatures between~ 10
to~ 30 kK. Knowing the properties of these objects is important to understand massive star …

Context. It is well known that massive O stars are frequently (if not always) found in binary or
higher-order multiple systems, but this fact has been less robustly investigated for the lower …

Surveys in the Milky Way and Large Magellanic Cloud have revealed that the majority of
massive stars will interact with companions during their lives. However, knowledge of the …

Context. With the aim of understanding massive stars and their feedback in the early epochs
of our Universe, the ULLYSES and XShootU collaborations collected the biggest …
