Submillimetre water masers at 437, 439, 471, and 474 GHz towards evolved stars. APEX observations and radiative transfer modelling
P. Bergman, E. M. L. Humphreys
Here we aim to characterise submillimetre water masers at 437, 439, 471, and 474 GHz towards a sample of evolved stars. We used the Atacama Pathfinder Experiment (APEX) to observe…
The shock-heated atmosphere of an asymptotic giant branch star resolved by ALMA
Wouter Vlemmings, Theo Khouri, Eamon O'Gorman +8
Our current understanding of the chemistry and mass-loss processes in solar-like stars at the end of their evolution depends critically on the description of convection, pulsations…
Resolving the stellar activity of the Mira AB binary with ALMA
W. H. T. Vlemmings, S. Ramstedt, E. O'Gorman +4
We present the size, shape and flux densities at millimeter continuum wavelengths, based on ALMA science verification observations in Band 3 (~94.6 GHz) and Band 6 (~228.7 GHz), fr…
ALMA sub-mm maser and dust distribution of VY Canis Majoris
A. M. S. Richards, C. M. V. Impellizzeri, E. M. Humphreys +25
Cool, evolved stars have copious, enriched winds. The structure of these winds and the way they are accelerated is not well known. We need to improve our understanding by studying…
Outflow Structure and Velocity Field of Orion Source I: ALMA Imaging of SiO Isotopologue Maser and Thermal Emission
Florian Niederhofer, Elizabeth Humphreys, Ciriaco Goddi
Using Science Verification data from the Atacama Large Millimeter/Submillimeter Array (ALMA), we have identified and imaged five rotational transitions (J=5-4 and J=6-5) of the thr…
A Multi-Epoch Study of the Radio Continuum Emission of Orion Source I: Constraints on the Disk Evolution of a Massive YSO and the Dynamical History of Orion BN/KL
C. Goddi, E. M. L. Humphreys, L. J. Greenhill +2
We present new 7mm continuum observations of Orion BN/KL with the VLA. We resolve the emission from the protostar radio Source I and BN at several epochs. Source I is highly elonga…
Maser emission from SiO isotopologues traces the innermost 100 AU around Radio Source I in Orion BN/KL
C. Goddi, L. J. Greenhill, C. J. Chandler +3
We have used the Very Large Array (VLA) at 7 mm wavelength to image five rotational transitions (J=1-0) from three SiO isotopologues towards Orion BN/KL: 28SiO v=0,1,2; and 29SiO a…
