Antarctic TianMu Staring Observation Project II: Data reduction and preliminary results
Hubiao Niu, Jing Zhong, Yu Zhang +6
The Antarctic TianMu Staring Observation Program is a time-domain optical sky survey project carried out in Antarctica, capable of large sky coverage, high-cadence sampling, and lo…
Insights into the 3D layered structure of nearby open clusters through N-body simulations
Kaixiang Lang, Yu Zhang, Hubiao Niu +3
Context. Open clusters (OCs) are important for understanding star formation, dynamics, and evolution. Previous studies have indicated a relationship between cluster structure and m…
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…
First Detailed Analysis of a Relatively Deep, Low Mass-ratio Contact Binary: ATO J108.6991+27.8306
Shuo Ma, Jinzhong Liu, Yu Zhang +3
We present the first detailed photometric analysis of ATO J108.6991+27.8306 (hereinafter as J108). The short-period close binary J108 was observed by the Nanshan 1 m Wide Field Tel…
Searching for Variable Stars in the Open Cluster NGC 2355 and Its Surrounding Region
Hong Wang, Yu Zhang, Xiangyun Zeng +4
We have investigated the variable stars in the field surrounding NGC 2355 based on the time-series photometric observation data. More than 3000 CCD frames were obtained in the V ba…
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…
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…
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…
Gravitational-wave radiation from double compact objects with eLISA in the Galaxy
Jinzhong Liu, Yu Zhang
The phase of in-spiral of double compact objects (DCOs: NS+WD, NS+NS, BH+NS, and BH+BH binaries) in the disk field population of the Galaxy provides a potential source in the frequ…
The impact of binary stars on the colors of high-redshift galaxies
Y. Zhang, J. Liu, F. Zhang +1
Evolutionary population synthesis (EPS) models play an important role in many studies on the formation and evolution of galaxies. Most EPS models are still poorly calibrated for ce…
The gravitational wave signal from isolated objects
Jinzhong Liu, Yu Zhang
According to the theoretical study, a deformation object (e.g., a spinning non-axisymmetric pulsar star) will radiate a gravitational wave (GW) signal during an accelaration motion…
Integrated spectral energy distributions of binary star composite stellar populations
Zhongmu Li, Liyun Zhang, Jinzhong Liu
This paper presents theoretical integrated spectral energy distributions (SEDs) of binary star composite stellar populations (bsCSPs) in early-type galaxies, and how the bsCSP mode…
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…
