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…
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…
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…
Chemical tracers of a highly eccentric AGB-main sequence star binary
T. Danilovich, J. Malfait, M. Van de Sande +32
Binary interactions have been proposed to explain a variety of circumstellar structures seen around evolved stars, including asymptotic giant branch (AGB) stars and planetary nebul…
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…
The VLT/SPHERE view of the ATOMIUM cool evolved star sample. I. Overview: Sample characterization through polarization analysis
M. Montargès, E. Cannon, A. de Koter +32
Aims. Through the ATOMIUM project, based on an ALMA large program, we aim to present a consistent view of a sample of 17 nearby cool evolved stars (Aymptotic Giant Branch and red s…
3D hydrodynamical survey of the impact of a companion on the morphology and dynamics of AGB outflow
Jolien Malfait, Silke Maes, Ward Homan +4
With the use of high-resolution ALMA observations, complex structures that resemble those observed in post-AGB stars and planetary nebulae are detected in the circumstellar envelop…
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…
ATOMIUM: ALMA tracing the origins of molecules in dust forming oxygen rich M-type stars: Motivation, sample, calibration, and initial results
C. A. Gottlieb, L. Decin, A. M. S. Richards +33
This overview paper presents ATOMIUM, a Large Programme in Cycle 6 with the Atacama Large Millimeter-submillimeter Array (ALMA). The goal of ATOMIUM is to understand the dynamics a…
ATOMIUM: Halide molecules around the S-type AGB star W Aquilae
T. Danilovich, M. Van de Sande, J. M. C. Plane +36
S-type asymptotic giant branch (AGB) stars are thought to be intermediates in the evolution of oxygen- to carbon-rich AGB stars. The chemical compositions of their circumstellar en…
SPH modelling of wind-companion interactions in eccentric AGB binary systems
J. Malfait, W. Homan, S. Maes +4
The late evolutionary stages of low- and intermediate-mass stars are characterised by mass loss through a dust-driven stellar wind. Recent observations reveal complex structures wi…
SPH modelling of companion-perturbed AGB outflows including a new morphology classification scheme
S. Maes, W. Homan, J. Malfait +4
Asymptotic giant branch (AGB) stars are known to lose a significant amount of mass by a stellar wind, which controls the remainder of their stellar lifetime. High angular-resolutio…
Atomium: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae. I. Morpho-kinematical interpretation of CO and SiO emission
Ward Homan, Bannawit Pimpanuwat, Fabrice Herpin +36
Evolved low- to intermediate-mass stars are known to shed their gaseous envelope into a large, dusty, molecule-rich circumstellar nebula which typically develops a high degree of s…
