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…
Carbon chemistry in IRC+10216: Infrared detection of diacetylene
J. P. Fonfría, M. Agúndez, J. Cernicharo +2
We present the detection of C4H2 for first time in the envelope of the C-rich AGB star IRC+10216 based on high spectral resolution mid-IR observations carried out with the Texas Ec…
Circumstellar ammonia in oxygen-rich evolved stars
K. T. Wong, K. M. Menten, T. Kamiński +3
The circumstellar ammonia (NH) chemistry in evolved stars is poorly understood. Previous observations and modelling showed that NH abundance in oxygen-rich stars is several…
IRTF/TEXES Observations of the HII Regions H1 and H2 in the Galactic Centre
Hui Dong, John H. Lacy, Rainer Schodel +6
We present new [Ne II] (12.8 micron) IRTF/TEXES observations of the Galactic Center HII regions H1 and H2, which are at a projected distance of ~11 pc from the center of the Galaxy…
The abundance of 28Si32S, 29Si32S, 28Si34S, and 30Si32S in the inner layers of the envelope of IRC+10216
J. P. Fonfria, J. Cernicharo, M. J. Richter +3
We present high spectral resolution mid-IR observations of SiS towards the C-rich AGB star IRC+10216 carried out with the Texas Echelon-cross-Echelle Spectrograph mounted on the NA…
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…
