Deep and low mass-ratio contact binaries and their third bodies
Liying Zhu, Shengbang Qian, Wenping Liao +6
Deep and low mass-ratio contact binaries (DLMCBs) are believed to be in the final stage of their contact phase, potentially leading to the formation of fast-rotating single stars s…
Multi-color and TESS photometric investigation of four lo mass-ratio contact binary systems
Ahmed Waqas Zubairi, Zhao Ergang, Qian Shengbang +2
We present the TESS and BVRcIc light curves solution of four low mass-ratio contact binary systems TIC 159102550), V1068 Her, MW Pav and TIC 321576458. Except MW Pav, all three sys…
Investigation of superhumps in SU UMa-type dwarf novae based on the observations of TESS
Wei Liu, Shengbang Qian
We report the superhumps analysis of seven SU UMa-type dwarf novae based on the observations of Transiting Exoplanet Survey Satellite (TESS). Superhumps are seen during superoutbur…
A spectral data release for 104 Type II Supernovae from the Tsinghua Supernova Group
Han Lin, Xiaofeng Wang, Jujia Zhang +33
We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…
Spectroscopic properties of the dwarf nova-type cataclysmic variables observed by LAMOST
Han Zhongtao, Boonrucksar Soonthornthum, Qian Shengbang +5
Spectra of 76 known dwarf novae from the LAMOST survey were presented. Most of the objects were observed in quiescence, and about 16 systems have typical outburst spectra. 36 of th…
Physical properties and evolutionary status of the W-subtype contact binary V502 Oph with a stellar companion
Xiao Zhou, Shengbang Qian, Binghe Huang +2
Multi-color ( ) CCD photometric light curves of the contact binary V502 Oph are analyzed using the Wilson-Devinney (W-D) program. The solutions reveal that V502 O…
