Effects on vsini determinations of O stars from 3D model atmospheres with high turbulent velocities
L. Delbroek, J. O. Sundqvist, F. Backs +3
When studying massive stars and their life cycles, rotation plays a key role. Hence, understanding the rotation of these stars is crucial when determining their properties, or for…
A rotational line CO cooling rate prescription for AGB outflows
T. Ceulemans, F. De Ceuster, O. Vermeulen +1
Asymptotic Giant Branch (AGB) stars significantly contribute to the chemical composition of the universe. In their outflows, complex chemistry takes place, which critically depends…
Evidence for the Keplerian orbit of a close companion around a giant star
Mats Esseldeurs, Leen Decin, Joris De Ridder +31
Close companions influence stellar evolution through tidal interactions, mass transfer, and mass loss effects. While such companions are detected around young stellar objects, main…
Impact of a binary companion in AGB outflows on CO spectral lines
Owen Vermeulen, Mats Esseldeurs, Jolien Malfait +7
In the late stage of their evolution, low- to intermediate-mass stars pass through the asymptotic giant branch (AGB) phase, characterised by strong mass loss through dust driven wi…
A numerically stable comoving frame solver for line radiative transfer
Thomas Ceulemans, Frederik De Ceuster, Leen Decin
Radiative transfer is essential in astronomy, both for interpreting observations and simulating various astrophysical phenomena. However, self-consistent line radiative transfer is…
ATOMIUM: Continuum emission and evidence of dust enhancement from binary motion
T. Danilovich, N. Samaratunge, Y. Mori +35
Low- and intermediate-mass stars on the asymptotic giant branch (AGB) account for a significant portion of the dust and chemical enrichment in their host galaxy. Here we present AL…
Magritte, a modern software library for spectral line radiative transfer
Thomas Ceulemans, Frederik De Ceuster, Leen Decin +1
Spectral line observations are an indispensable tool to remotely probe the physical and chemical conditions throughout the universe. Modelling their behaviour is a computational ch…
Modelling predicts a molecule-rich disk around the AGB star L2 Puppis
M. Van de Sande, C. Walsh, T. Danilovich +2
The nearby oxygen-rich AGB star L2 Pup hosts a well-studied nearly edge-on disk. To date, disks around AGB stars have not been chemically studied in detail. By combining a paramete…
Bayesian model reconstruction based on spectral line observations
Frederik De Ceuster, Thomas Ceulemans, Leen Decin +2
Spectral line observations encode a wealth of information. A key challenge, therefore, lies in the interpretation of these observations in terms of models to derive the physical an…
ATOMIUM: Molecular inventory of 17 oxygen-rich evolved stars observed with ALMA
S. H. J. Wallstrom, T. Danilovich, H. S. P. Muller +35
The dusty winds of cool evolved stars are a major contributor of the newly synthesised material enriching the Galaxy and future generations of stars. However, the details of the ph…
Radiative Transfer as a Bayesian Linear Regression problem
Frederik De Ceuster, Thomas Ceulemans, Jon Cockayne +2
Electromagnetic radiation plays a crucial role in various physical and chemical processes. Hence, almost all astrophysical simulations require some form of radiative transfer model…
