Competition between gravity waves excited by convection and tides in stars that host a companion
M. Esseldeurs, J. Ahuir, L. Amard +2
Asteroseismology has become a powerful tool in stellar astrophysics, offering unprecedented insights into the internal structures and dynamics of stars. It enables precise characte…
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…
Eppur si eclissa: Eccentric low-mass companions and time-in-dust selection explain long secondary periods
Leen Decin, Owen Vermeulen, Mats Esseldeurs +5
[abbreviated] Long Secondary Periods (LSPs) are observed in about one third of pulsating red giants yet remain unexplained. Four key observational constraints anchor the discussion…
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…
Binarity at LOw Metallicity (BLOeM): Bayesian inference of natal kicks from inert black hole binaries
R. Willcox, P. Marchant, A. Vigna-Gómez +15
Context. The emerging population of inert black hole binaries (BHBs) provides a unique opportunity to constrain black hole (BH) formation physics. These systems are composed of a s…
An accreting dwarf star orbiting the S-type giant star pi1 Gru
M. Montargès, J. Malfait, M. Esseldeurs +20
Aims. We aim to characterize the properties of the inner companion of the S-type AGB star pi1 Gru and to identify plausible future evolutionary scenarios for this triple system. Me…
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…
SPH modelling of AGB wind morphology in hierarchical triple systems \& comparison to observation of R Aql
Jolien Malfait, Lionel Siess, Owen Vermeulen +7
Asymmetric 3D structures are observed in the outflows of evolved low- and intermediate-mass stars, and are believed to be shaped through the interaction of companions that are hidd…
Impact of HI cooling and study of accretion disks in AGB wind-companion smoothed particle hydrodynamic simulations
Jolien Malfait, Lionel Siess, Mats Esseldeurs +4
High-resolution observations reveal that the outflows of evolved low- and intermediate-mass stars harbour complex morphological structures that are linked to the presence of one or…
Tidal Dissipation in Evolved Low and Intermediate Mass Stars
M. Esseldeurs, S. Mathis, L. Decin
As the observed occurrence for planets or stellar companions orbiting low and intermediate-mass evolved stars is increasing, so does the importance of understanding and evaluating…
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…
3D simulations of AGB stellar winds -- II. Ray-tracer implementation and impact of radiation on the outflow morphology
Mats Esseldeurs, Lionel Siess, Frederik De Ceuster +6
Stars with an initial mass below ~ 8 Msun evolve through the asymptotic giant branch (AGB) phase, during which they develop strong stellar winds. Recent observations have revealed…
Route towards complete 3D hydro-chemical simulations of companion-perturbed AGB outflows
Silke Maes, Lionel Siess, Ward Homan +6
Low- and intermediate mass stars experience a significant mass loss during the last phases of their evolution, which obscures them in a vast, dusty envelope. Although it has long b…
