Si-bearing molecules towards IRC+10216: ALMA unveils the molecular envelope of CWLeo

We report the detection during the ALMA Cycle 0 of SiS rotational lines in high-vibrational states as well as SiO and SiC_2 lines in their ground vibrational state, towards IRC+10216. The spatial distribution of these molecules shows compact emission for SiS and a more extended emission for SiO and SiC_2... Show more
