ATOMIUM: Inner circumstellar envelopes of oxygen-rich AGB stars as revealed by highly excited SiO lines
B. Pimpanuwat, S. Etoka, M. D. Gray +14
Silicon monoxide (SiO) traces the physical conditions and dynamics in the circumstellar envelopes (CSEs) of AGB stars. We present high-resolution ALMA Band 6 observations of highly…
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…
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…
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 unusual 3D distribution of NaCl around the AGB star IK Tau
A. Coenegrachts, T. Danilovich, F. De Ceuster +1
NaCl is a diatomic molecule with a large dipole moment, which allows for its detection even at relatively small abundances. It has been detected towards several evolved stars, amon…
How to disentangle geometry and mass-loss rate from AGB-star spectral energy distributions -- The case of EP Aqr
J. Wiegert, M. A. T. Groenewegen, A. Jorissen +2
High-angular-resolution observations of asymptotic giant branch (AGB) stars often reveal non-spherical morphologies for the gas and dust envelopes. We aim to make a pilot study to…
Dust-gas chemistry in AGB outflows: Chemical modelling of dust-gas chemistry within AGB outflows I. Effect on the gas-phase chemistry
M. Van de Sande, C. Walsh, T. P. Mangan +1
Chemical modelling of AGB outflows is typically focused on either non-thermodynamic equilibrium chemistry in the inner region or photon-driven chemistry in the outer region. We inc…
Constraints on metal oxide and metal hydroxide abundances in the winds of AGB stars - Potential detection of FeO in R Dor
L. Decin, T. Danilovich, D. Gobrecht +4
Using ALMA, we observed the stellar wind of two oxygen-rich Asymptotic Giant Branch (AGB) stars, IK Tau and R Dor, between 335 and 362 GHz. One aim was to detect metal oxides and m…
