On the Determination of Stellar Mass and Binary Fraction of Open Clusters within 500 pc from the Sun
Yueyue Jiang, Jing Zhong, Songmei Qin +3
We investigated the stellar mass function and the binary fraction of 114 nearby open clusters (OCs) using the high-precision photometric data from Gaia Data Release 3 (Gaia DR3). W…
The new detection of blue straggler stars in 50 open clusters using Gaia DR3
Chunyan Li, Jing Zhong, Songmei Qin +1
The particularly abundant presence of blue straggler stars (BSS) in Galactic open clusters offers favorable conditions for detailed studies on the statistical properties and the or…
Value-added catalog of M-giant stars in LAMOST DR9
Jing Li, Lin Long, Jing Zhong +9
In this work, we update the catalog of M-giant stars from the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 9. There…
The role of binarity and stellar rotation in the split main sequence of NGC 2422
Chenyu He, Weijia Sun, Chengyuan Li +8
In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (~ 600 Myr-2 Gyr-old) star clusters, some younger clusters even exhibit split main seq…
New insights into the structure of open clusters in the Gaia era
Jing Zhong, Li Chen, Yueyue Jiang +2
With the help of Gaia data, it is noted that in addition to the core components, there are low-density outer halo components in the extended region of open clusters. To study the e…
New Open Cluster candidates Found in Galactic Disk Using Gaia DR2/EDR3 Data
Zhihong He, Chunyan Li, Jing Zhong +6
We report 541 new open cluster candidates in Gaia EDR3 through revisiting the cluster results from an earlier analysis of the Gaia DR2, which revealed nearly a thousand open cluste…
GRB 140423A: A Case of Stellar Wind to Interstellar Medium Transition in the Afterglow
Long Li, Xiang-Gao Wang, WeiKang Zheng +14
We present very early ground-based optical follow-up observations of GRB~140423A, which was discovered by \emph{Swift}/BAT and by {\it Fermi}/GBM. Its broadband afterglow was monit…
Early Optical Observations of GRB 150910A: Bright Jet Optical Afterglow and X-ray Dipole Radiation from a Magnetar Central Engine
Lang Xie, Xiang-Gao Wang, Song-Mei Qin +10
Gamma-ray burst (GRB) 150910A was detected by {\it Swift}/BAT, and then rapidly observed by {\it Swift}/XRT, {\it Swift}/UVOT, and ground-based telescopes. We report Lick Observato…
Is GRB 110715A the progenitor of FRB 171209?
Xiang-Gao Wang, Long Li, Yuan-Pei Yang +5
The physical origin of fast radio bursts (FRBs) is unknown. Young magnetars born from gamma-ray bursts (GRBs) have been suggested to be a possible central engine of FRBs. We test s…
How Bad/Good Are the External Forward Shock Afterglow Models of Gamma-Ray Bursts?
Xiang-Gao Wang, Bing Zhang, En-Wei Liang +8
The external forward shock (EFS) models have been the standard paradigm to interpret the broad-band afterglow data of gamma-ray bursts (GRBs). One prediction of the models is that…
