Charting circumstellar chemistry of carbon-rich asymptotic giant branch stars. II. Abundances and spatial distributions of CS
R. Unnikrishnan, M. Andriantsaralaza, E. De Beck +9
The circumstellar envelopes (CSEs) of asymptotic giant branch (AGB) stars harbour a rich variety of molecules and are sites of complex chemistry. Our current understanding of the c…
ALMA observations of CO isotopologues towards six obscured post-AGB stars
T. Khouri, D. Tafoya, W. H. T. Vlemmings +13
Low- and intermediate-mass stars evolve through the asymptotic giant branch (AGB), when an efficient mass-loss process removes a significant fraction of their initial mass. A subst…
An impressionist view of V Hydrae. When MATISSE paints Asymmetric Giant Blobs
L. Planquart, C. Paladini, A. Jorissen +29
Our purpose is to study the effect of binary companions located within the first 10 stellar radii from the primary AGB star. In this work, we target the mass-losing carbon star V H…
Probing the dynamical and kinematical structures of detached shells around AGB stars
M. Maercker, E. De Beck, T. Khouri +6
Aims. We aim to resolve the spatial and kinematic sub-structures in five detached-shell sources to provide detailed constraints for hydrodynamic models that describe the formation…
