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…
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…
MACE: A Machine learning Approach to Chemistry Emulation
S. Maes, F. De Ceuster, M. Van de Sande +1
The chemistry of an astrophysical environment is closely coupled to its dynamics, the latter often found to be complex. Hence, to properly model these environments a 3D context is…
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…
Sensitivity study of chemistry in AGB outflows using chemical kinetics
S. Maes, M. Van de Sande, T. Danilovich +2
Asymptotic Giant Branch (AGB) stars shed a significant amount of their mass in the form of a stellar wind, creating a vast circumstellar envelope (CSE). Owing to the ideal combinat…
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…
Magritte, a modern software library for 3D radiative transfer: II. Adaptive ray-tracing, mesh construction and reduction
Frederik De Ceuster, Jan Bolte, Ward Homan +6
Radiative transfer is a notoriously difficult and computationally demanding problem. Yet, it is an indispensable ingredient in nearly all astrophysical and cosmological simulations…
