Telluric absorption lines in the ALMA spectra of Car
Zulema Abraham, Pedro. P. B. Beaklini, Pierre Cox +2
The massive binary system formed by Car and an unknown companion is a strong source at millimetre and submillimetre wavelengths. Close to the stars, continuum bremsstrahlung an…
HD101584: Circumstellar characteristics and evolutionary status
H. Olofsson, T. Khouri, M. Maercker +8
We have performed a study of the characteristics of the circumstellar environment of the binary object HD101584, that provides information on a likely evolutionary scenario. We hav…
Opening PANDORA's box: APEX observations of CO in PNe
L. Guzman-Ramirez, A. I. Gomez-Ruiz, H. M. J. Boffin +5
Context. Observations of molecular gas have played a key role in developing the current understanding of the late stages of stellar evolution. Aims. The survey Planetary nebulae AN…
First detection of methanol towards a post-AGB object, HD101584
H. Olofsson, W. H. T. Vlemmings, P. Bergman +5
The circumstellar environments of objects on the asymptotic giant branch and beyond are rich in molecular species. Nevertheless, methanol has never been detected in such an object,…
ALMA Observations of the Water Fountain Pre-Planetary Nebula IRAS 16342-3814: High-velocity bipolar jets and an Expanding Torus
R. Sahai, W. H. T. Vlemmings, T. Gledhill +4
We have mapped 12CO J=3-2 and other molecular lines from the "water-fountain" bipolar pre-planetary nebula (PPN) IRAS 16342-3814 with ~0."35 resolution using ALMA. We find (i) two…
Witnessing the Emergence of a Carbon Star
L. Guzman-Ramirez, E. Lagadec, R. Wesson +9
During the late stages of their evolution, Sun-like stars bring the products of nuclear burning to the surface. Most of the carbon in the Universe is believed to originate from sta…
