VLBI observations of SiO masers at 43 and 86 GHz in AGB stars.

, 2003
We present the results of the 1st simultaneous observations of SiO masers at a wavelength of 3 and 7 mm with VLBI techniques. We have obsd. the J = 1-0 and J = 2-1 rotational lines in the v = 1 and v = 2 vibrationally excited states of the most abundant ...

VLBA Observations of H2O Masers Around the Evolved Star W434K

, 2013
We present observations and preliminary results of H2O maser emissions in the circumstellar envelope of the evolved star W434K, obtained by the very large baseline array at the three epochs from 2003 to 2004 with time spacing between 2-3 months.

High-resolution observations of 6.7-GHz methanol masers with the Long Baseline Array

, 2004
We have used the Australian Long Baseline Array (LBA) to produce milliarcsecond images of five sites of methanol (CH3OH) maser emission at 6.7 GHz. These are all sites that have linear morphologies at arcsecond resolutions, which have been hypothesized ...
