Long-term Simultaneous Monitoring Observations of SiO and H2O Masers toward the Mira Variable WX Serpentis
Jang-Ho Lim, Jaeheon Kim, Se-Hyung Cho +4
We present the results from long-term simultaneous monitoring observations of SiO and H2O masers toward the Mira variable star WX Serpentis. This study has been conducted with 21m…
Asymmetric distributions of H2O and SiO masers towards V627 Cas
Haneul Yang, Se-Hyung Cho, Youngjoo Yun +7
We performed simultaneous observations of the H2O 6(1,6) - 5(2,3) (22.235080 GHz) and SiO v= 1, 2, J = 1 - 0, SiO v = 1, J = 2 - 1, 3 - 2 (43.122080, 42.820587, 86.243442, and 129.…
Time variations of H2O and SiO masers in the proto-Planeatry Nebula OH231.8+4.2
J. Kim, S. -H. Cho, V. Bujarrabal +4
H2O (22 GHz) and SiO masers (43, 86, 129 GHz) in the bipolar proto-planetary nebula OH231.8+4.2 were simultaneously monitored using the 21-m antennas of the Korean VLBI Network in…
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…
Single dish performance of KVN 21-m radio telescopes:Simultaneous observations at 22 and 43 GHz
Sang-Sung Lee, Do-Young Byun, Chung Sik Oh +30
We report simultaneous multi-frequency observing performance at 22 and 43 GHz of the 21-m shaped-Cassegrain radio telescopes of the Korean VLBI Network (KVN). KVN is the first mill…
