Methanol masers as tools to study high-mass star formation [PDF]
, 2007 In this contribution I will attempt to show that the study of Galactic 6.7 and 12.2GHz methanol masers themselves, as opposed to the use of methanol masers as signposts, can yield important conclusions contributing to the understanding of high-mass star ...

Circumstellar SiO Masers in the Bulge Asymmetries and Dynamical Evolution Survey [PDF]
, 2019 The Bulge Asymmetries and Dynamical Evolution (BAaDE) project aims to explore the complex structure of the inner Galaxy and Galactic Bulge, by using the 43 GHz receivers at the Karl G. Jansky Very Large Array (VLA) and the 86 GHz receivers at the Atacama

Polarization observations of circumstellar OH masers
, 2010 International audienceResults of observations of circumstellar OH masers in lines with wavelengths near 18 cm are reported. The observations were carried out on the radio telescope of the Nan cay Radio Astronomy Observatory (France).

First VLBI mapping of circumstellar
, 2005 We report the first VLBI map of the $v=0$ $J=$ 1–0 maser line of 29SiO in the long-period variable star IRC +10011. We have found that this maser emission is composed of multiple spots distributed in an incomplete ring, suggesting that this maser is ...

Inward motions of the compact SiO masers around VX Sagittarii
, 2006 We report Very Long Baseline Array (VLBA) observations of 43 GHz upsilon = 1, J = 1-0 SiO masers in the circumstellar envelope of the M-type semiregular variable star VX Sgr at three epochs during 1999 April-May.

The masers towards IRAS 20126 + 4104
, 2005 We present MERLIN observations of OH, water and methanol masers towards the young high mass stellar object IRAS 20126+4104. Emission from the 1665-MHz OH, 22-GHz H2O and 6.7-GHz CH3OH masers is detected and all originates very close to the central ...

The magnetic field around late-type stars revealed by the circumstellar H
, 2005 Through polarization observations, circumstellar masers are excellent probes of the magnetic field in the envelopes of late-type stars. Whereas observations of the polarization of the SiO masers close to the star and on the OH masers much further out ...

Continuum Emission Associated with 6.7-GHz Methanol Masers
, 1996 We have used the Australia Telescope Compact Array (ATCA) to search for continuum emission toward three strong 6.7-GHz methanol maser sources. For two of the sources, G 339.88 - 1.26 and NGC 6334F (G 351.42 + 0.64), we detect continuum emission closely ...

FG3: spatial and frequency modeling of circumstellar masers
, 2007 We have developed a computer program (called "FG3") that is useful to model images of spectral line emission. We have applied it successfully to the study of maser emission in the circumstellar envelopes of late-type stars.

Non-local radiative transfer of SiO masers in Miras
, 2012 Context. To properly understand the propagation of SiO masers within the shocked region of the circumstellar envelope of asymptotic giant branch stars, non-local radiative transfer calculations are required. Aims.
