Exploration of the origin of 2020 X-ray outburst in OJ 287
Shifeng Huang, Shaoming Hu, Hongxing Yin +3
Research into OJ 287 has been ongoing for many years. In 2020 April-June, this source underwent the second highest X-ray outburst (second only to the 2016-2017 outburst) and the me…
Rapid X-ray Variability in Mkn 421 during a Multiwavelength Campaign
Alex G. Markowitz, Krzysztof Nalewajko, Gopal Bhatta +47
The study of short-term variability properties in AGN jets has the potential to shed light on their particle acceleration and emission mechanisms. We report results from a four-day…
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.…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
A possible giant planet orbiting the cataclysmic variable LX Ser
K. Li, S. -M. Hu, J. -L. Zhou +6
LX Ser is a deeply eclipsing cataclysmic variable with an orbital period of . Sixty two new eclipse times were determined by our observations and the AAVSO Internatio…
