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…

3D Maser polarization simulation for J=1-0 SiO masers in the circumstellar envelope of an AGB star
M. Phetra, M. D. Gray, K. Asanok +4
SiO masers from AGB stars exhibit variability in intensity and polarization during a pulsation period. This variability is explained by radiative transfer and magnetic properties o…

First VLBI Imaging of SiO , Masers in VY Canis Majoris
Hiroko Shinnaga, Miyako Oyadomari, Hiroshi Imai +8
We achieved the first VLBI detections of the ground vibrational state () SiO (hereafter, SiO) and SiO masers of the rotational transitions, to…
