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…
The growth of carbon chains in IRC+10216 mapped with ALMA
M. Agundez, J. Cernicharo, G. Quintana-Lacaci +9
Linear carbon chains are common in various types of astronomical molecular sources. Possible formation mechanisms involve both bottom-up and top-down routes. We have carried out a…
The peculiar distribution of CH3CN in IRC+10216 seen by ALMA
M. Agundez, J. Cernicharo, G. Quintana-Lacaci +4
IRC+10216 is a circumstellar envelope around a carbon-rich evolved star which contains a large variety of molecules. According to interferometric observations, molecules are distri…
Molecular shells in IRC+10216: tracing the mass loss history
J. Cernicharo, N. Marcelino, M. Agundez +1
The ejecta of thermally-pulsating AGB stars largely control the chemical evolution of galaxies. Yet, both, the mass-loss process and the gas chemical composition remain poorly unde…
