CO line observations of OH/IR stars in the inner Galactic Bulge: Characteristics of stars at the tip of the AGB
H. Olofsson, T. Khouri, B. A. Sargent +10
12CO and 13CO lines, as well as a mm-wave continuum, have been observed for a sample of 22 OH/IR stars in directions within 2 degrees of the Galactic Centre. Photometry data have b…
Observational identification of a sample of likely recent Common-Envelope Events
Theo Khouri, Wouter Vlemmings, Daniel Tafoya +5
One of the most poorly understood stellar evolutionary paths is that of binary systems undergoing common-envelope evolution, when the envelope of a giant star engulfs the orbit of…
ATOMIUM: ALMA tracing the origins of molecules in dust forming oxygen rich M-type stars: Motivation, sample, calibration, and initial results
C. A. Gottlieb, L. Decin, A. M. S. Richards +33
This overview paper presents ATOMIUM, a Large Programme in Cycle 6 with the Atacama Large Millimeter-submillimeter Array (ALMA). The goal of ATOMIUM is to understand the dynamics a…
ALMA observations of the vibrationally-excited rotational CO transition towards five AGB stars
T. Khouri, W. H. T. Vlemmings, S. Ramstedt +3
We report the serendipitous detection with ALMA of the vibrationally-excited pure-rotational CO transition towards five asymptotic giant branch (AGB) stars, Cet, R…
The mass-loss rates of red supergiants at low metallicity: Detection of rotational CO emission from two red supergiants in the Large Magellanic Cloud
Mikako Matsuura, B. Sargent, Bruce Swinyard +9
Using the PACS and SPIRE spectrometers on-board the Herschel Space Observatory, we obtained spectra of two red supergiants (RSGs) in the Large Magellanic Cloud (LMC). Multiple rota…
ALMA Observations of Anisotropic Dust Mass-loss in the Inner Circumstellar Environment of the Red Supergiant VY Canis Majoris
E. O'Gorman, W. Vlemmings, A. M. S. Richards +8
The processes leading to dust formation and the subsequent role it plays in driving mass loss in cool evolved stars is an area of intense study. Here we present high resolution ALM…
