The R2Pub Telescopes for Surveying: An Overview and Performance Evaluation of the System
Xuan Song, Xiaofeng Wang, Jin Zhu +29
The R2Pub telescope, built by the Beijing Planetarium, is a 60 cm equatorial binocular telescope located at the Daocheng site of Yunnan Observatories in China, at an altitude of ab…
A Disk-Originated 329-day Quasi-Periodic Oscillation in the Seyfert 1 Galaxy J1626+5120
Litao Zhu, Zhongxiang Wang, Dong Zheng +2
The Seyfert 1 galaxy J1626+5120 is estimated to host a black hole (BH) accreting at Eddington ratio . Its long-term multi-band…
LEIA discovery of the longest-lasting and most energetic stellar X-ray flare ever detected
Xuan Mao, He-Yang Liu, Song Wang +40
The Lobster Eye Imager for Astronomy (LEIA) detected a new X-ray transient on 2022 November 7, identified as a superflare event occurring on a nearby K-type giant star HD 251108. T…
Prospects of the multi-channel photometric survey telescope in the cosmological application of Type Ia supernovae
Zhenyu Wang, Ju-Jia Zhang, Xinzhong Er +1
The Multi-channel Photometric Survey Telescope (Mephisto) is a real-time, three-color photometric system designed to capture the color evolution of stars and transients accurately.…
The environments of Type Ia supernovae with different relative equivalent width of Si II feature in their spectra
Xiang-Cun Meng, Ju-Jia Zhang, Xu-Lin Zhao +2
Although type Ia supernovae are so important in many astrophysical field, e.g. in cosmology, their explosion mechanism and progenitor system are still unclear. In physics, the rela…
Optical Properties of Crich (C, SiC and FeC) Dust Layered Structure of Massive Stars
Ruiqing Wu, Mengqiu Long, Xiaojiao Zhang +9
The composition and structure of interstellar dust are important and complex for the study of the evolution of stars and the \textbf{interstellar medium} (ISM). However, there is a…
Optical and Ultraviolet Monitoring of the Black Hole X-ray Binary MAXI J1820+070/ASASSN-18ey for 18 Months
Hanna Sai, Xiaofeng Wang, Jianfeng Wu +20
MAXI J1820+070 is a low-mass black hole X-ray binary system with high luminosity in both optical and X-ray bands during the outburst periods. We present extensive photometry in X-r…
Active Galactic Nuclei with Ultra-fast Outflows Monitoring Project: The Broad-line Region of Mrk 79 as a Disk Wind
Kai-Xing Lu, Jin-Ming Bai, Zhi-Xiang Zhang +23
We developed a spectroscopic monitoring project to investigate the kinematics of the broad-line region (BLR) in active galactic nuclei (AGN) with ultra-fast outflows (UFOs). Mrk~79…
Lijiang 2.4-meter Telescope and its Instruments
Chuan-Jun Wang, Jin-Ming Bai, Yu-Feng Fan +32
Lijiang 2.4-meter Telescope(LJT), the largest common-purpose optical telescope in China, has been applied to the world-wide astronomers since 2008. It is located at Gaomeigu site,…
The physical constraints on a new LoBAL QSO at z=4.82
Weimin Yi, Richard Green, Jin-Ming Bai +26
Very few low-ionization broad absorption line (LoBAL) QSOs have been found at high redshifts to date. One high-redshift LoBAL QSO, J0122+1216, was recently discovered at the Lijian…
A Luminous Peculiar Type Ia Supernova SN 2011hr: More Like SN 1991T or SN 2007if?
Jujia Zhang, Xiaofeng Wang, Michele Sasdelli +23
Photometric and spectroscopic observations of a slowly declining, luminous Type Ia supernova (SN Ia) SN 2011hr in the starburst galaxy NGC 2691 are presented. SN 2011hr is found to…
