Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii
Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii
The supergiant VX Sagittarii is a strong emitter of both H2O and SiO masers. However, previous VLBI observations have been performed separately, which makes it difficult to spatially trace the outward transfer of the material consecutively. Here we present the astrometrically registered, simultaneous maps of 22.2 GHz H2O and 43.1/42.8/86.2/129.3 …
