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 …

Our understanding of massive star evolution is in flux due to recent upheavals in our view of
mass loss and observations of a high binary fraction among O-type stars. Mass-loss rates for …

Aims. Many topical astrophysical research areas, such as the properties of planet host stars,
the nature of the progenitors of different types of supernovae and gamma ray bursts, and the …

We present results of a systematic study of failing core-collapse supernovae and the
formation of stellar-mass black holes (BHs). Using our open-source general-relativistic 1.5 D …

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 have constructed a comprehensive grid of 1540 metal line-blanketed, NLTE, plane-
parallel, hydrostatic model atmospheres for the basic parameters appropriate to early B-type …

We analyse the observed fractions of core-collapse supernova (SN) types from the Lick
Observatory Supernova Search (LOSS), and we discuss the corresponding implications for …

We report the discovery and early observations of the peculiar Type IIn supernova (SN)
2006gy in NGC 1260. With a peak visual magnitude of about-22, it is the most luminous …

We have performed a pilot study of mass loss predictions for late-type Wolf-Rayet (WR) stars
as a function of metal abundance, over a range between Z. We find that the winds of …

During the late stages of stellar evolution in massive stars (C fusion and later), the fusion
luminosity in the core of the star exceeds the star's Eddington luminosity. This can drive …
