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…
IRC+10216 mass loss properties through the study of 3mm emission: Large spatial scale distribution of SiO, SiS, and CS
L. Velilla-Prieto, J. Cernicharo, M. Agúndez +4
The study of the gas in the envelopes surrounding asymptotic giant branch (AGB) stars through observations in the millimetre wavelength range provides information about the history…
Discovery of the first Ca-bearing molecule in space: CaNC
J. Cernicharo, L. Velilla-Prieto, M. Agúndez +6
We report on the detection of calcium isocyanide, CaNC, in the carbon-rich evolved star IRC+10216. We derived a column density for this species of (2.00.5)10 cm…
Detection of highly excited OH towards AGB stars: A new probe of shocked gas in the extended atmospheres
T. Khouri, L. Velilla-Prieto, E. De Beck +5
We report the detection and investigate the properties of high-excitation lambda-doubling line emission of hydroxyl (OH) detected towards three asymptotic giant branch (AGB) stars…
Gas infall and possible circumstellar rotation in R Leo
J. P. Fonfría, M. Santander-García, J. Cernicharo +4
We present new interferometer molecular observations of R Leo taken at 1.2 mm with the Atacama Large Millimeter Array with an angular resolution up to ~0.026 arcsec. These observat…
