The binary and the disk: the beauty is found within NGC3132 with JWST
Raghvendra Sahai, Valentin Bujarrabal, Guillermo Quintana-Lacaci +4
The planetary nebula (PN) NGC3132 is a striking example of the dramatic but poorly understood, mass-loss phenomena that (1-8) Msun stars undergo during their death throes as they e…
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…
THROES: a caTalogue of HeRschel Observations of Evolved Stars. I. PACS range spectroscopy
J. Ramos-Medina, C. Sánchez Contreras, P. García-Lario +3
This is the first of a series of papers presenting the THROES (A caTalogue of HeRschel Observations of Evolved Stars) project, intended to provide a comprehensive overview of the s…
Molecular ions in the O-rich evolved star OH231.8+4.2: HCO,HCO and first detection of SO, NH, and HO
C. Sánchez Contreras, L. Velilla Prieto, M. Agúndez +8
OH 231.8+4.2, a bipolar outflow around a Mira-type variable star, displays a unique molecular richness amongst circumstellar envelopes (CSEs) around O-rich AGB and post-AGB stars.…
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…
IRAS 19520+2759: a 10^5 Lsun massive young stellar object driving a collimated outflow
Aina Palau, Carmen Sánchez Contreras, Raghvendra Sahai +2
The theory of massive star formation currently suffers from a scarce observational base of massive young stellar objects to compare with. In this paper, we present OVRO CO(1-0), 13…
