Binary stars are as common as single stars. Binary stars are of immense importance to
astrophysicists because that they allow us to determine the masses of the stars independent …

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 …

Recent studies of massive binaries with putative black hole companions have uncovered a
phase of binary evolution that has not been observed before, featuring a bloated stripped …

Context. The outcome of the formation of massive stars is an important anchor point in the
formation and evolution process of these stars. It provides insight into the physics of the …

The majority of massive stars are found in close binaries which:(i) are prone to merge and
(ii) are accompanied by another distant tertiary star (triples). Here, we study the evolution of …

Context. Significant progress has been made toward understanding the formation of
massive (M> 8 M⊙) binaries in close orbits (with periods of less than a month). Some of the …

Context. Characterising the outcome of the star formation process is key to understand and
predict the evolution of stellar populations. Especially the fraction of massive stars in young …

We simulate mergers between star clusters embedded within their natal giant molecular
cloud. We extract initial conditions from cloud-scale simulations of cluster formation and …

Context. Given the high incidence of binaries among mature field massive stars, it is clear
that multiplicity is an inevitable outcome of high-mass star formation. Understanding how …

We present the visual orbits of four spectroscopic binary stars, HD 61859, HD 89822, HD
109510, and HD 191692, using long baseline interferometry with the CHARA Array. We also …
