CO rotational line emission in very red carbon stars in the Magellanic Clouds
M. A. T. Groenewegen, A. Nanni, M. L. Boyer +11
Stars of low and intermediate initial mass lose most of their stellar mass at the end of their lives during the asymptotic giant branch (AGB) phase. Determining their gas and dust…
Exploring circumstellar chemistry in X-ray emitting AGB stars
J. Alonso-Hernández, C. Sánchez Contreras, M. Agúndez +5
Aims. Our goal is to characterize the chemistry and physical conditions of the circumstellar envelopes (CSEs) of Asymptotic Giant Branch (AGB) binary candidate stars with UV-excess…
An accreting dwarf star orbiting the S-type giant star pi1 Gru
M. Montargès, J. Malfait, M. Esseldeurs +20
Aims. We aim to characterize the properties of the inner companion of the S-type AGB star pi1 Gru and to identify plausible future evolutionary scenarios for this triple system. Me…
ATOMIUM: Continuum emission and evidence of dust enhancement from binary motion
T. Danilovich, N. Samaratunge, Y. Mori +35
Low- and intermediate-mass stars on the asymptotic giant branch (AGB) account for a significant portion of the dust and chemical enrichment in their host galaxy. Here we present AL…
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…
Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
G. C. Sloan, K. E. Kraemer, B. Aringer +9
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significan…
ATOMIUM: Molecular inventory of 17 oxygen-rich evolved stars observed with ALMA
S. H. J. Wallstrom, T. Danilovich, H. S. P. Muller +35
The dusty winds of cool evolved stars are a major contributor of the newly synthesised material enriching the Galaxy and future generations of stars. However, the details of the ph…
The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
The Spitzer Spectroscopic Survey of S-type Stars
K. Smolders, P. Neyskens, J. A. D. L. Blommaert +28
S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because of their peculiar chemical composition, one may expect a strong influence…
