X TrA through the eyes of MATISSE: More evidence of clumpy molecular layers around C-type asymptotic giant branch stars
V. Răstău, C. Paladini, J. Drevon +22
Aims. The goal of this study is to further the understanding of the wind formation mechanism in asymptotic giant branch (AGB) stars through the analysis of the close environment (w…
Detection of the linear SiC and SiC radicals in IRC\,+10216
José Cernicharo, Juan Ramón Pardo, Marcelino Agúndez +6
We detected the linear radicals SiC and SiC toward IRC+10216 using an ultrasensitive line survey gathered with the Yebes 40\,m radio telescope. The derived column d…
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…
Reevaluation of ALMA detection of circumstellar PH3 in the AGB envelope IRC+10216: evidence for misidentification with HCN
M. Agundez, L. Velilla-Prieto, J. P. Fonfria +1
The article "Confirmation of interstellar phosphine towards asymptotic giant branch star IRC+10216" by A. Manna and S. Pal uses ALMA data of the C-star envelope IRC+10216 to claim…
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…
