Periodic 6.7 GHz maser emission in G353.273+0.641: First candidate for a pulsating high-mass protostar
Sohta Harajiri, Kazuhito Motogi, Ryota Nakamura +3
We report on the periodic flux variations in the 6.7 GHz maser associated with the high-mass protostar G353.273+0.641, based on 13 yr of monitoring mainly by the…

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…

A Unified Maxwell-Bloch Framework for Multi-periodic 6.7 GHz Methanol Flaring in G9.62+0.20E
T. Rashidi, V. Anari, O. Powles +4
We analyze a decade of 6.7 GHz methanol monitoring data in G9.62+0.20E, confirming the known periodicities of p1 = 241.3 +/- 2.3 d and p2 = 52.5 +/- 0.3 d, and identifying three ne…
