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…
Identifying the Mechanisms of Water Maser Variability During the Accretion Burst in NGC6334I
Jakobus M. Vorster, James O. Chibueze, Tomoya Hirota +5
HMYSOs gain most of their mass in short bursts of accretion. Maser emission is an invaluable tool in discovering and probing accretion bursts. We observed the 22 GHz water maser re…
A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
R. A. Burns, Y. Uno, N. Sakai +34
High-mass protostars (M 8 M) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to be faci…
Ammonia masers toward G358.931-0.030
T. P. McCarthy, S. L. Breen, J. F. Kaczmarek +9
We report the detection of ammonia masers in the non-metastable (6, 3), (7, 5) and (6, 5) transitions, the latter is the first unambiguous maser detection of that transition ever m…
Detection of the longest periodic variability in 6.7 GHz methanol masers G5.900-0.430
Yoshihiro Tanabe, Yoshinori Yonekura, MacLeod C. Gordon
Long term monitoring observations with the Hitachi 32-m radio telescope of the 6.7 GHz methanol masers associated with the high mass star-forming region G5.900-0.430 is presented.…
A multi-transition methanol maser study of the accretion burst source G358.93-0.03-MM1
O. S. Bayandina, C. L. Brogan, R. A. Burns +8
We present the most complete to date interferometric study of the centimeter wavelength methanol masers detected in G358.93-0.03 at the burst and post-burst epochs. A unique, NIR/(…
