(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…
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…
H12CN and H13CN excitation analysis in the circumstellar outflow of R Scl
M. Saberi, M. Maercker, E. De Beck +3
Abridged. The 12CO/13CO ratio in the circumstellar envelope (CSE) of asymptotic giant branch (AGB) stars has been extensively used as the tracer of the photospheric 12C/13C ratio.…
ALMA Compact Array observations of the Fried Egg nebula: Evidence for large-scale asymmetric mass-loss from the yellow hypergiant IRAS 17163-3907
Sofia Wallstrom, E. Lagadec, S. Muller +12
Yellow hypergiants are rare and represent a fast evolutionary stage of massive evolved stars. That evolutionary phase is characterised by a very intense mass loss, the understandin…
Sub-arcsecond imaging of the water emission in Arp 220
S. König, S. Martín, S. Muller +14
Extragalactic observations of water emission can provide valuable insights into the excitation of the interstellar medium. In addition, extragalactic megamasers are powerful probes…
Detection of thermal radio emission from a single coronal giant
Eamon O'Gorman, Graham M. Harper, Wouter Vlemmings
We report the detection of thermal continuum radio emission from the K0 III coronal giant Pollux ( Gem) with the Karl G. Jansky Very Large Array (VLA). The star was detected at…
