The orbital period of the long-period and colliding-wind binary WR 146 from radio interferometry of the shock cone
Shiming Wen, Bo Zhang, Shuangjing Xu +8
We report the first measurement of the orbital period of a long-period colliding-wind binary (CWB) system WR 146, derived by tracing the rotational morphology of its wind-colliding…
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…
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 Rapidly Spinning Intermediate-Mass Black Hole 3XMM J150052.0+015452
Z. Cao, P. G. Jonker, S. Wen +2
A star tidally disrupted by a black hole can form an accretion disc with a super-Eddington mass accretion rate; the X-ray emission produced by the inner disc provides constraints o…
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…
Live to die another day: the rebrightening of AT2018fyk as a repeating partial tidal disruption event
T. Wevers, E. R. Coughlin, D. R. Pasham +13
Stars that interact with supermassive black holes (SMBHs) can either be completely or partially destroyed by tides. In a partial tidal disruption event (TDE) the high-density core…
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…
