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…
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…
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…
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…
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…
A detailed view of the gas shell around R Sculptoris with ALMA
M. Maercker, W. H. T. Vlemmings, M. Brunner +6
Thermal pulses are fundamental to the chemical evolution of AGB stars and their circumstellar envelopes. A further consequence of thermal pulses is the formation of detached shells…
