Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii

Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii

The red supergiant VX Sagittarii is a strong emitter of H2O and SiO masers, however its mass loss dynamics are still poorly understood. Here, the authors present astrometrically registered, simultaneous maps of SiO and H2O maser regions, and provide observational evidence for a break in spherical sy...
