Fast variability and circular polarization of the 6.7 GHz methanol maser in G33.6410.228
Kenta Fujisawa, Yui Sugiura, Yuta Kojima +5
The 6.7 GHz methanol maser in a high-mass star-forming region G33.6410.228 is known to exhibit burst-like flux variability due to an unknown mechanism. To investigate the burst…

Detection of OH maser emission in the 71-year periodic comet 12P/Pons-Brooks using the 40-m Thai National Radio Telescope (TNRT)
Nobuyuki Sakai, Saran Poshyachinda, Koichiro Sugiyama +44
Although the optical cometary database is extensive, the radio database is limited. The 18-cm OH maser observations of comets allow us to determine (i) the production rate of OH ($…

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…
