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…
Rotational spectra of vibrationally excited AlO and TiO in oxygen rich stars
T. Danilovich, C. A. Gottlieb, L. Decin +6
Rotational transitions in vibrationally excited AlO and TiO -- two possible precursors of dust -- were observed in the 300 GHz range (1 mm wavelength) towards the oxygen rich AGB s…
Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
(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…
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…
DEATHSTAR: Nearby AGB stars with the Atacama Compact Array I. CO envelope sizes and asymmetries: A new hope for accurate mass-loss-rate estimates
S. Ramstedt, W. H. T. Vlemmings, L. Doan +16
This is the first publication of the DEATHSTAR project. The goal of the project is to reduce the uncertainties of observational estimates of mass-loss rates from Asymptotic Giant B…
