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 …

This work presents a new plasma cooling curve that is calculated using the SPEX package.
We compare our cooling rates to those in previous works, and implement the new cooling …

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 …

According to our present understanding, long gamma-ray bursts (GRBs) originate from the
collapse of massive stars, while short bursts are caused by to the coalescence of compact …

We study the evolution of the interstellar and circumstellar media around massive stars (M⩾
40 M☉) from the main sequence (MS) through to the Wolf-Rayet (WR) stage by means of …

There is mounting observational evidence in favour of Luminous Blue Variables (LBVs)
being the direct progenitors of supernovae. Here we present possibly the most convincing …

ABSTRACT A signification fraction of Galactic massive stars () are ejected from their parent
cluster and supersonically sail away through the interstellar medium (ISM). The winds of …

Aims. We use VLT/UVES high-resolution optical spectroscopy of seven GRB afterglows (at z
GRB between 2.20 and 3.97) to investigate circumburst and interstellar plasma in the host …

ABSTRACT A very small fraction of (runaway) massive stars have masses exceeding and
are predicted to evolve as luminous blue variable and Wolf–Rayet stars before ending their …
