Cluster aggregates surrounding Pismis 5 in the Vela Molecular Ridge
Ming Feng Qin, Yu Zhang, Jinzhong Liu +5
Context. In the Gaia era, the precision of astrometric data is unprecedented. High-quality data make it easier to find more cluster aggregates and support further confirmation of t…
Decoding the Morphological Evolution of Open Clusters
Qingshun Hu, Yu Zhang, Ali Esamdin
Base on Gaia Second Data Release and the combination of nonparametric bivariate density estimation with the least square ellipse fitting, we derive the shape parameters of the samp…
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…
The effects of binary interactions on parameter determinations for early-type galaxies
Yu Zhang, Jinzhong Liu, Fenghui Zhang
Based on stellar population models without (SSP) and with (BSP) binary interactions, we investigate the effects of binary interactions on parameter determinations for early-type ga…
Determining gravitational wave radiation from close galaxy pairs using a binary population synthesis approach
Jinzhong Liu, Yu Zhang, Hailong Zhang +2
Context. The early phase of the coalescence of supermassive black hole (SMBH) binaries from their host galaxies provides a guaranteed source of low-frequency (nHz-Hz) gravitatio…
Testing three derivative methods of stellar population synthesis models
Yu Zhang, Zhanwen Han, Jinzhong Liu +2
The number of methods used to study the properties of galaxies is increased, and testing these methods is very important. Galactic globular clusters (GCs) provide an excellent medi…
