The Abundance of SiC2 in Carbon Star Envelopes: Evidence that SiC2 is a gas-phase precursor of SiC dust
S. Massalkhi, M. Agúndez, J. Cernicharo +6
Silicon carbide dust is ubiquitous in circumstellar envelopes around C-rich AGB stars. However, the main gas-phase precursors leading to the formation of SiC dust have not yet been…
The abundances of polyacetylenes towards CRL618
J. P. Fonfría, J. Cernicharo, M. J. Richter +1
We present a mid-infrared high spectral resolution spectrum of CRL618 in the frequency ranges 778-784 and 1227-1249 cm^-1 (8.01-8.15 and 12.75-12.85 um) taken with the Texas Echelo…
Silicon in the dust formation zone of IRC +10216 as observed with PACS and SPIRE on board Herschel
L. Decin, J. Cernicharo, M. J. Barlow +36
The interstellar medium is enriched primarily by matter ejected from evolved low and intermediate mass stars. The outflows from these stars create a circumstellar envelope in which…
High-J v=0 SiS Maser Emission in IRC+10216: A New Case of Infrared Overlaps
J. P. Fonfría Expósito, M. Agúndez, B. Tercero +2
We report on the first detection of maser emission in the J=11-10, J=14-13 and J=15-14 transitions of the v=0 vibrational state of SiS toward the C-rich star IRC+10216. These maser…
