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…
One month convection timescale on the surface of a giant evolved star
W. Vlemmings, T. Khouri, B. Bojnordi Arbab +2
The transport of energy through convection is important during many stages of stellar evolution, and is best studied in our Sun or giant evolved stars. Features that are attributed…
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…
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…
