VLBI Astrometry of Radio Stars to Link Radio and Optical Celestial Reference Frames: Observing Strategies
Jingdong Zhang, Bo Zhang, Shuangjing Xu +12
The Gaia celestial reference frame (Gaia-CRF) will benefit from a close assessment with independent methods, such as Very Long Baseline Interferometry (VLBI) measurements of radio…
VLBI Astrometry of Radio Stars to Link Radio and Optical Celestial Reference Frames. I. HD 199178 AR Lacertae
Wen Chen, Bo Zhang, Jingdong Zhang +6
To accurately link the radio and optical Celestial Reference Frames (CRFs) at optical bright end, i.e., with Gaia G band magnitude < 13, increasing number and improving sky distrib…
The parallax and 3D kinematics of water masers in the massive star-forming region G034.43+0.24
Xiaofeng Mai, Bo Zhang, M. J. Reid +12
We report a trigonometric parallax measurement of 22 GHz water masers in the massive star-forming region G034.43+0.24 as part of the Bar and Spiral Structure Legacy (BeSSeL) Survey…
The Astrometric Animation of Water Masers towards the Mira Variable BX Cam
Shuangjing Xu, Hiroshi Imai, Youngjoo Yun +20
We report VLBI monitoring observations of the 22 GHz water (HO) masers around the Mira variable BX Cam, which were carried out as a part of the EAVN Synthesis of Stellar Mase…
A VLBA Trigonometric Parallax for RR Aql and the Mira PL Relation
Yan Sun, Bo Zhang, Mark J. Reid +4
We report VLBA observations of 22 GHz HO and 43 GHz SiO masers toward the Mira variable RR Aql. By fitting the SiO maser emission to a circular ring, we estimate the absolute…
