Chemical complexity and dust formation around evolved stars
Marie Van de Sande
The outflows of asymptotic giant branch (AGB) stars are rich astrochemical laboratories, hosting different chemical regimes: from non-equilibrium chemistry close to the star, to du…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
Chemical modelling of dust-gas chemistry within AGB outflows -- II. Effect of the dust-grain size distribution
M. Van de Sande, C. Walsh, T. Danilovich
AGB stars are, together with supernovae, the main contributors of stellar dust to the interstellar medium (ISM). Dust grains formed by AGB stars are thought to be large. However, a…
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…
Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
L. Decin, W. Homan, T. Danilovich +12
In 1981, the idea of a superwind that ends the life of cool giant stars was proposed. Extreme OH/IR-stars develop superwinds with the highest mass-loss rates known so far, up to a…
An ALMA view of CS and SiS around oxygen-rich AGB stars
T. Danilovich, A. M. S. Richards, A. I. Karakas +3
We aim to determine the distributions of molecular SiS and CS in the circumstellar envelopes of oxygen-rich asymptotic giant branch stars and how these distributions differ between…
