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…
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…
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…
