We present a detailed report of the connection between long‐duration gamma‐ray bursts
(GRBs) and their accompanying supernovae (SNe). The discussion presented here places …

Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously
with core-collapse supernovae (SNe), thus linking by a common thread nature's two …

The striking broad emission line spectroscopic appearance of Wolf-Rayet (WR) stars has
long defied analysis, owing to the extreme physical conditions within their line-and …

We present grids of massive star evolution models at four different metallicities ($ Z= 0.004,
0.002, 0.001, 0.00001$). The effects of rotation on the stellar structure and the transport of …

The prompt γ-ray emission from γ-ray bursts (GRBs) should be detectable out to distances of
z> 10 (ref.), and should therefore provide an excellent probe of the evolution of cosmic star …

Core-collapse supernova remnants are structures of the interstellar medium (ISM) left
behind the explosive death of most massive stars (). Since they result in the expansion of the …

New NTT/EMMI spectrophotometry of single WN2–5 stars in the Small and Large Magellanic
Clouds are presented, from which He ii λ4686 line luminosities have been derived, and …

We investigate properties of the interstellar medium (ISM) in galaxies hosting long-duration γ-
ray bursts (GRBs) from an analysis of atomic species (Mg 0, Fe 0) and excited fine-structure …

We present a new mechanism for the ejection of a common envelope in a massive binary,
where the energy source is nuclear energy rather than orbital energy. This can occur during …

Thanks to dedicated long-term missions like Voyager and GOES over the past 50 years,
much insight has been gained on the activity of our Sun, the solar wind, its interaction with …
