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…
Clues to NaCN formation
G. Quintana-Lacaci, J. Cernicharo, L. Velilla Prieto +5
ALMA is providing us essential information on where certain molecules form. Observing where these molecules emission arises from, the physical conditions of the gas, and how this r…
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…
