Simultaneous VLBI Astrometry of H2O and SiO Masers toward the Semiregular Variable R Crateris

Dong-Jin Kim, Se-Hyung Cho, Youngjoo Yun +7

We obtained, for the first time, astrometrically registered maps of the 22.2 GHz H2O and 42.8, 43.1, and 86.2 GHz SiO maser emission toward the semiregular b-type variable (SRb) R…

Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii

Dong-Hwan Yoon, Se-Hyung Cho, Youngjoo Yun +8

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 spatial…
