Spectroscopic evidence for a large spot on the dimming Betelgeuse
Sofya Alexeeva, Gang Zhao, Dong-Yang Gao +4
During October 2019 and March 2020, the luminous red supergiant Betelgeuse demonstrated an unusually deep minimum of its brightness. It became fainter by more than one magnitude an…
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…
