The X-ray outburst of PG 1553+113: A precession effect of two jets in the supermassive black hole binary system
Shifeng Huang, Hongxing Yin, Shaoming Hu +4
Blazar PG 1553+113 is thought to be a host of supermassive black hole binary (SMBHB) system. A 2.2-year quasi-periodicity in the -ray light curve was detected, possibly result o…
Two contact binaries with mass ratios close to the minimum mass ratio
Kai Li, Qi-Qi Xia, Chun-Hwey Kim +5
The cut-off mass ratio is under debate for contact binaries. In this paper, we present the investigation of two contact binaries with mass ratios close to the low mass ratio limit.…
Constraining Evolution of Magnetic Field Strength in Dissipation Region of Two BL Lac Objects
Xu-Liang Fan, Da-Hai Yan, Qing-Wen Wu +1
With the assumption that the optical variability timescale is dominated by the cooling time of the synchrotron process for BL Lac objects, we estimate time dependent magnetic field…
A possible tidal disruption event candidate in the black hole binary system of OJ 287
Shifeng Huang, Shaoming Hu, Hongxing Yin +4
The BL Lacertae OJ 287 is a supermassive black holes binary (SMBHB) system with complex physics of its irregular flares. During 2016 October -- 2017 April period, a surprising outb…
Simulating Photometric Images of Moving Targets with Photon-mapping
Junju Du, Shaoming Hu, Xu Chen +2
We present a novel, easy-to-use method based on the photon-mapping technique to simulate photometric images of moving targets. Realistic images can be created in two passes: photon…
Photometric study and absolute parameters estimation of six totally eclipsing contact binaries
Kai Li, Qi-Qi Xia, Chun-Hwey Kim +6
High precision CCD observations of six totally eclipsing contact binaries were presented and analyzed. It is found that only one target is an A-type contact binary (V429 Cam), whil…
