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…
Registration of HO and SiO masers in the Calabash Nebula, to confirm the Planetary Nebula paradigm
Richard Dodson, Maria Rioja, Valentin Bujarrabal +4
We report on the astrometric registration of VLBI images of the SiO and water masers in OH231.8+4.2, the iconic Proto-Planetary Nebula also known as the Calabash nebula, using the…
