The circumstellar environment around the extreme Galactic red supergiant NML Cygni: Dense, dusty, and asymmetric
E. De Beck, H. Andrews, G. Quintana-Lacaci +1
Supernova observations imply the presence of a dense and asymmetric circumstellar environment around SN Type II progenitors, whereas the mass loss from these progenitors, namely, r…
First detection of silicon-bearing molecules in Car
C. Bordiu, J. R. Rizzo, F. Bufano +11
We present ALMA band 6 observations of the luminous blue variable Eta Car, obtained within the ALMAGAL program. We report SiO J=5-4, SiS J=12-11 and SiN N=5-4 emission in the equat…
Dissecting the central regions of OH 231.8 + 4.2 with ALMA: a salty rotating disk at the base of a young bipolar outflow
C. Sánchez Contreras, J. Alcolea, R. Rodríguez Cardoso +5
We present ALMA continuum and molecular line emission maps at 1 mm of OH 231.8, a well studied bipolar nebula around an AGB star. The excellent angular resolution of our maps…
Clues to NaCN formation
G. Quintana-Lacaci, J. Cernicharo, L. Velilla Prieto +5
ALMA is providing us essential information on where certain molecules form. Observing where these molecules emission arises from, the physical conditions of the gas, and how this r…
IRC +10 216 in 3-D: morphology of a TP-AGB star envelope
M. Guélin, N. A. Patel, M. Bremer +10
During their late pulsating phase, AGB stars expel most of their mass in the form of massive dusty envelopes, an event that largely controls the composition of interstellar matter.…
Discovery of SiCSi in IRC+10216: A missing link between gas and dust carriers of SiC bonds
J. Cernicharo, M. C. McCarthy, C. A. Gottlieb +13
We report the discovery in space of a disilicon species, SiCSi, from observations between 80 and 350 GHz with the IRAM 30m radio telescope. Owing to the close coordination between…
New N-bearing species towards OH231.8+4.2: HNCO, HNCS, HCN and NO
L. Velilla Prieto, C. Sánchez Contreras, J. Cernicharo +7
OH231.8+4.2 is a well studied O-rich CSE around an intermediate-mass evolved star that displays bipolar molecular outflows accelerated up to 400 km/s. OH231 also presents an except…
Dense Gas in M33 (HerM33es)
C. Buchbender, C. Kramer, M. Gonzalez-Garcia +13
We aim to better understand the emission of molecular tracers of the diffuse and dense gas in giant molecular clouds and the influence that metallicity, optical extinction, density…
Herschel/HIFI observations of red supergiants and yellow hypergiants: I. Molecular inventory
D. Teyssier, G. Quintana-Lacaci, A. P. Marston +17
Red supergiant stars (RSGs) and yellow hypergiant stars (YHGs) are believed to be the high-mass counterparts of stars in the AGB and early post-AGB phases. We study the mass-loss i…
The Herschel M33 extended survey (HerM33es): PACS spectroscopy of the star forming region BCLMP 302
B. Mookerjea, C. Kramer, C. Buchbender +19
Context: The emission line of [CII] at 158 micron is one of the strongest cooling lines of the interstellar medium (ISM) in galaxies. Aims: Disentangling the relative contributions…
