Maser emission from the CO envelope of the asymptotic giant branch star W Hydrae
W. H. T. Vlemmings, T. Khouri, D. Tafoya
Observation of CO emission around asymptotic giant branch (AGB) stars is the primary method to determine gas mass-loss rates. While radiative transfer models have shown that molecu…
DEATHSTAR: Nearby AGB stars with the Atacama Compact Array II. CO envelope sizes and asymmetries: The S-type stars
M. Andriantsaralaza, S. Ramstedt, W. H. T. Vlemmings +13
We aim to constrain the sizes of the CO circumstellar envelopes (CSEs) of 16 S-type stars, along with an additional 7 and 4 CSEs of C-type and M-type AGB stars, respectively. We ma…
SiO masers and 7 mm Continuum in Mira and R Aqr
W. D. Cotton, E. Humphreys, M. Wittkowski +5
Interactions between AGB stars and a secondary in a close orbit are one possible explanation of why some AGB stars develop into aspherical planetary nebulae. This study uses millim…
Heavy-element Rydberg transition line emission from the post-giant-evolution star HD101584
H. Olofsson, J. H. Black, T. Khouri +7
We report the detection of two lines at millimetre wavelengths towards the immediate surroundings of the post-giant and most likely post-common-envelope star HD101584 using high-an…
(Sub)stellar companions shape the winds of evolved stars
L. Decin, M. Montargès, A. M. S. Richards +32
Binary interactions dominate the evolution of massive stars, but their role is less clear for low- and intermediate-mass stars. The evolution of a spherical wind from an asymptotic…
VLTI/PIONIER reveals the close environment of the evolved system HD101584
J. Kluska, H. Olofsson, H. Van Winckel +9
Context: The observed orbital characteristics of post-asymptotic giant branch (post-AGB) and post-red giant branch (post-RGB) binaries are not understood. We suspect that the missi…
