Simultaneous Detection of Optical Flares of the Magnetically Active M Dwarf Wolf 359
Han-Tang Lin, Wen-Ping Chen, Jinzhong Liu +13
We present detections of stellar flares of Wolf\,359, an M6.5 dwarf in the solar neighborhood (2.41~pc) known to be prone to flares due to surface magnetic activity. The observatio…
Deciphering Star Cluster Evolution by Shape Morphology
Qingshun Hu, Yu Zhang, Ali Esamdin +2
We analyze the morphological evolution of open clusters and provide shape parameters for 265 open clusters. The results show that the overall shape of sample clusters becomes more…
Diagnosing the Stellar Population and Tidal Structure of the Blanco1 Star Cluster
Yu Zhang, Shih-Yun Tang, W. P. Chen +2
We present the stellar population, using {\it Gaia}\,DR2 parallax, kinematics, and photometry, of the young (~Myr), nearby (~pc) open cluster, Blanco1. A total…
An optical and X-ray study of the contact binary, BH Cassiopeiae
Junhui Liu, Ali Esamdin, Yu Zhang +10
We present the revised and high quality CCD time series observations in 2017 and 2018 of the W UMa-type contact binary BH~Cas. The combination of our new determinations of minimum…
Pulsations of the SX Phe Star BL Camelopardalis
Peng Zong, Ali Esamdin, Jian Ning Fu +6
We carried out photometric observations of the SX Phe star BL Cam in 2014, 2017 and 2018 using Nanshan 1-m telescope. In addition to the dominated frequency of 25.5790(3) cd…
Diagnosing the Clumpy Protoplanetary Disk of the UXor Type Young Star GM Cephei
P. C. Huang, W. P. Chen, M. Mugrauer +29
UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM\,Cephei is such a UXor in the young (~M…
