ATOMIUM: Inner circumstellar envelopes of oxygen-rich AGB stars as revealed by highly excited SiO lines
B. Pimpanuwat, S. Etoka, M. D. Gray +14
Silicon monoxide (SiO) traces the physical conditions and dynamics in the circumstellar envelopes (CSEs) of AGB stars. We present high-resolution ALMA Band 6 observations of highly…
ATOMIUM: Continuum emission and evidence of dust enhancement from binary motion
T. Danilovich, N. Samaratunge, Y. Mori +35
Low- and intermediate-mass stars on the asymptotic giant branch (AGB) account for a significant portion of the dust and chemical enrichment in their host galaxy. Here we present AL…
Chemical tracers of a highly eccentric AGB-main sequence star binary
T. Danilovich, J. Malfait, M. Van de Sande +32
Binary interactions have been proposed to explain a variety of circumstellar structures seen around evolved stars, including asymptotic giant branch (AGB) stars and planetary nebul…
Maser Flares Driven by Isothermal Shock Waves
M. D. Gray, S. Etoka, B. Pimpanuwat +1
We use 3D computer modelling to investigate the timescales and radiative output from maser flares generated by the impact of shock-waves on astronomical unit-scale clouds in inters…
ATOMIUM: Probing the inner wind of evolved O-rich stars with new, highly excited HO and OH lines
A. Baudry, K. T. Wong, S. Etoka +17
Water and the hydroxyl radical are major constituents of the envelope of O-rich late-type stars. Transitions involving energy levels that are highly excited have been observed in b…
The VLT/SPHERE view of the ATOMIUM cool evolved star sample. I. Overview: Sample characterization through polarization analysis
M. Montargès, E. Cannon, A. de Koter +32
Aims. Through the ATOMIUM project, based on an ALMA large program, we aim to present a consistent view of a sample of 17 nearby cool evolved stars (Aymptotic Giant Branch and red s…
Sciences with Thai National Radio Telescope
Phrudth Jaroenjittichai, Koichiro Sugiyama, Busaba H. Kramer +44
This White Paper summarises potential key science topics to be achieved with Thai National Radio Telescope (TNRT). The commissioning phase has started in mid 2022. The key science…
Stringent limits on SiO maser emission from the recurrent nova T Coronae Borealis
A. Evans, B. Pimpanuwat, A. M. S. Richards +5
There are indications that the third known eruption of the recurrent nova T CrB is imminent, and multi-wavelength observations prior to the eruption are important to characterise t…
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…
ATOMIUM: Halide molecules around the S-type AGB star W Aquilae
T. Danilovich, M. Van de Sande, J. M. C. Plane +36
S-type asymptotic giant branch (AGB) stars are thought to be intermediates in the evolution of oxygen- to carbon-rich AGB stars. The chemical compositions of their circumstellar en…
Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
Analysis of Methanol Maser Flares in G107.298+5.63 andS255-NIRS3
M. D. Gray, S. Etoka, B. Pimpanuwat
A 3D maser model has been used to perform an inverse problem on the light curves from three high-amplitude maser flares, selected on the basis of contemporaneous infra-red observat…
Maser Flares Driven by Variations in Pumping and Background Radiation
M. D. Gray, S. Etoka, A. Travis +1
We simulate maser flares by varying either the pump rate or the background level of radiation in a 3D model of a maser cloud. We investigate the effect of different cloud shapes, s…
