The Orion-KL super water maser

The Astrophysical Journal, 1989
The most powerful water maser feature ever seen in Orion was monitored for seven years. The maser reached a peak flux density of about 6.7 x 10 to the 6th Jy. The total radiated energy between August 1979 and June 1987 was 6 x 10 to the 39th ergs.

VLBI Monitoring Observations of Water Masers Around the Semi-Regular Variable Star R Crateris

, 2001
We monitored water-vapor masers around the semi-regular variable star R Crateris with the Japanese VLBI Network (J-Net) at the 22 GHz band during four epochs with intervals of one month.

Water masers in late-type stars

The Astrophysical Journal, 1985
A detailed model for the water masers in late-type stars was worked out using the cross sections calculated recently by Green. Inversion of the 22 GHz maser line, resulting from collisional excitations of the H/sub 2/O rotation levels, was obtained. The maser luminosity is increasing with the mass-loss rate. Photon outputs comparable to those observed,

Masers

, 2011
An astrophysical MASER (Microwave Amplification by Stimulated Emission of Radiation) is a source of stimulated spectral line emission. Maser emission is observed from the circumstellar envelopes of evolved stars, molecular clouds/star-forming regions ...

Dynamics of the 6.7 and 12.2 GHz methanol masers around Cepheus A HW2

, 2010
The 6.7 GHz methanol maser is exclusively associated with high-mass star formation. However, it remains unclear what structures harbour the methanol masers.

Massive star-formation toward G28.87+0.07 (IRAS 18411-0338) investigated by means of maser kinematics and radio to infrared, continuum observations

, 2012
We used the Very Long Baseline Array (VLBA) and the European VLBI Network (EVN) to perform phase-referenced VLBI observations of the three most powerful maser transitions associated with the high-mass star-forming region G28.87+0.07: the 22.2 GHz H$_{2 ...
