Long-term Simultaneous Monitoring Observations of SiO and H2O Masers toward the Mira Variable WX Serpentis

open access: yesThe Astrophysical Journal Supplement Series
We present the results from long-term simultaneous monitoring observations of SiO and H _2 O masers toward the Mira variable star WX Serpentis. This study has been conducted with 21 m single-dish radio telescopes of the Korean VLBI Network from 2009 June

Polarization properties of R Cas SiO masers

open access: yes, 2012
Silicon monoxide maser emission has been detected in the circumstellar envelopes of many evolved stars. It is a good tracer of the wind dynamics within a few stellar radii of the central star.

SiO maser emission from red supergiants across the Galaxy

open access: yes, 2012
Aims. Red supergiants (RSGs) are among the most luminous of all stars, easily detectable in external galaxies, and may ideally serve as kinematic tracers of Galactic structure.

Outflow structure and velocity field of Orion source

open access: yes, 2012
Using Science Verification data from the Atacama Large Millimeter/Submillimeter Array (ALMA), we have identified and imaged five rotational transitions (J = 5–4 and J = 6–5) of the three silicon monoxide isotopologues 28SiO v = 0, 1, 2 and 29SiO v = 0 ...

2MM WAVELENGTH VLBI OF SiO MASERS

open access: yes, 2003
Author Institution: MIT-Haystack ObservatoryCircumstellar envelopes of both proto-stars and evolved stars are rich molecular media which often support astronomical masers of several molecular species.

Studies of circumstellar shells in AGB stars by multifrequency (sub)mm-VLBI observations of maser emission

open access: yes, 2016
International audienceVLBI observations of maser emission are a basic tool to study the circumstellar envelopes (CSEs) around evolved stars, mainly around AGB and post-AGB stars.

The Structure and Polarization Properties of the SiO Masers in the Extended Atmosphere of R Aquarii

open access: yes, 1997
Silicon monoxide (SiO) maser emission has been observed towards many late-type stars. The conditions necessary for the formation of SiO masers dictate that they be produced in a region which is inside the silicate dust formation point close to the ...
