In the past decade, a consensus has emerged regarding the nature of classical Be stars:
They are very rapidly rotating main sequence B stars, which, through a still unknown, but …

The theory and numerical modelling of radiation processes and radiative transfer play a key
role in astrophysics: they provide the link between the physical properties of an object and …

We study the emission from tidal disruption events (TDEs) produced as radiation from black
hole accretion propagates through an extended, optically thick envelope formed from stellar …

Hyperion is a new three-dimensional dust continuum Monte-Carlo radiative transfer code
that is designed to be as generic as possible, allowing radiative transfer to be computed …

Rapid rotation is a fundamental characteristic of classical Be stars and a crucial property
allowing for the formation of their circumstellar disks. Past evolution in a mass and angular …

Recent observations discovered that some repeating fast radio bursts (FRBs) show
complicated variations and reversals of Faraday rotation measures (RMs), indicating that the …

Context. LS I+ 61 303 is a puzzling Be/X-ray binary with variable gamma-ray emission up to
TeV energies. The nature of the compact object and the origin of the high-energy emission …

Context. About 2/3 of the Be stars present the so-called variations, a phenomenon
characterized by the quasi-cyclic variation in the ratio between the violet and red emission …

Be stars possess gaseous circumstellar disks that modify in many ways the spectrum of the
central B star. Furthermore, they exhibit variability at several timescales and for a large …
