Multi-line study of the radial extent of SiO, CS, and SiS in AGB envelopes
S. Massalkhi, M. Agundez, J. P. Fonfria +3
The spatial distribution of molecules in AGB circumstellar envelopes is regulated by different processes. In the outer layers all molecules are destroyed due to the interaction wit…
Multi-frequency high spectral resolution observations of HCN toward the circumstellar envelope of Y CVn
J. P. Fonfría, E. J. Montiel, J. Cernicharo +7
High spectral resolution observations toward the low mass-loss rate C-rich, J-type AGB star Y CVn have been carried out at 7.5, 13.1 and 14.0 um with SOFIA/EXES and IRTF/TEXES. Aro…
The abundance of S- and Si-bearing molecules in O-rich circumstellar envelopes of AGB stars
S. Massalkhi, M. Agúndez, J. Cernicharo +1
Aims: We aim to determine the abundances of SiO, CS, SiS, SO, and SO in a large sample of oxygen-rich AGB envelopes covering a wide range of mass loss rates to investigate the…
Study of CS, SiO, and SiS abundances in carbon star envelopes: Assessing their role as gas-phase precursors of dust
S. Massalkhi, M. Agúndez, J. Cernicharo
Aim: We aim to determine the abundances of CS, SiO, and SiS in a large sample of carbon star envelopes covering a wide range of mass loss rates to investigate the potential role th…
The Abundance of SiC in Carbon Star Envelopes
Sarah Massalkhi, M. Agúndez, J. Cernicharo +2
Silicon carbide dust grains are ubiquitous in circumstellar envelopes around C-rich AGB stars. However, the main gas-phase precursors leading to the formation of SiC dust have not…
