RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…
KIC 5623923: A Faint Eclipsing Binary Consisting of Scuti pulsations
Tao-Zhi Yang, Zhao-Yu Zuo, Shi-ping Guo +4
In this paper, we present a detailed analysis of the light variation of KIC 5623923 using high-precision time-series data from the mission. The analysis reveals this targe…

Chao Wu, Yun Wang, Hua-Li Li +84
Early multiwavelength observations offer crucial insights into the nature of the relativistic jets responsible for gamma-ray bursts and their interaction with the surrounding mediu…
An H Cloud in the HI Tail: Recent Star Formation in the Outskirts of NGC 4258 Revealed by Nanshan 1-m Telescope
Cheng Cheng, Jia-Sheng Huang, Peng Wei +12
We present first-light deep H imaging taken with the Nanshan 1-meter wide-field telescope on the local galaxy NGC 4258, alongside archival data from Hubble Space telescope (HST…
SN 2021hpr: A Normal Type Ia Supernova Showing Excess Emission in the Early Rising Phase
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +37
We present extensive optical observations of a nearby Type Ia supernova (SN Ia), SN 2021hpr, located in the spiral galaxy NGC 3147 at a distance of 45 Mpc. Our observations…
