Metal Abundance and Kinematical Properties of M81 Globular Cluster System
Jun Ma, Zhenyu Wu, Tianmeng Zhang +7
In this paper, we presented metal abundance properties of 144 M81 globular clusters. These globulars consist of the largest globular cluster sample in M81 till now. Our main result…
Age and mass studies for young star clusters in M31 from SEDs-fit
Song Wang, Jun Ma, Zhou Fan +4
In this paper, we present photometry for young star clusters in M31, which are selected from Caldwell et al. These star clusters have been observed as part of the Beijing--Arizona-…
Spectroscopic Study of Globular Clusters in the Halo of M31 with Xinglong 2.16m Telescope II: Dynamics, Metallicity and Age
Zhou Fan, Ya-Fang Huang, Jin-Zeng Li +3
(Abridged) We performed the spectroscopic observations of 11 confirmed GCs in M31 with the Xinglong 2.16m telescope and we mainly focus on the fits method and the metallicity gradi…
Age and structure parameters of a remote M31 globular cluster B514 based on HST, 2MASS, GALEX and BATC observations
Jun Ma, Song Wang, Zhenyu Wu +3
B514 is a remote M31 globular cluster which locating at a projected distance of R_p~55 kpc. Deep observations with the Advanced Camera for Surveys (ACS) on the Hubble Space Telesco…
Spectroscopic Study of Globular Clusters in the Halo of M31 with Xinglong 2.16m Telescope
Zhou Fan, Ya-Fang Huang, Jin-Zeng Li +5
We present the spectroscopic observations for 11 confirmed globular clusters of M31 with the OMR spectrograph on 2.16m telescope at Xinglong site of National Astronomical Observato…
Stellar Population Properties and Evolution Analysis of NGC 628 with the Panchromatic Photometry
Hu Zou, Wei Zhang, Yanbin Yang +7
Panchromatic spectral energy distribution (SED) from the ultraviolet (UV), optical to infrared (IR) photometry of NGC 628, combined with the evolutionary stellar population synthes…
Age and mass constraints for a young massive cluster in M31 based on spectral-energy-distribution fitting
Jun Ma, Song Wang, Zhenyu Wu +4
VDB0-B195D is a massive, blue star cluster in M31. It was observed as part of the Beijing-Arizona-Taiwan-Connecticut (BATC) Multicolor Sky Survey using 15 intermediate-band filters…
An updated catalog of M31 globular-like clusters: UBVRI photometry, ages, and masses
Zhou Fan, Richard de Grijs, Xu Zhou
We present an updated UBVRI photometric catalog containing 970 objects in the field of M31, selected from the Revised Bologna Catalog (RBC v.4.0), including 965, 967, 965, 953, and…
Determination of fundamental properties of an M31 globular cluster from main-sequence photometry
Jun Ma, Zhenyu Wu, Song Wang +5
M31 globular cluster B379 is the first extragalactic cluster, the age of which was determined by main-sequence photometry. In this method, the age of a cluster is obtained by fitti…
The Correlations between the Intrinsic Colors and Spectroscopic Metallicities of M31 Globular Clusters
Zhou Fan, Jun Ma, Xu Zhou +1
We present the correlations between the spectroscopic metallicities and ninety-three different intrinsic colors of M31 globular clusters, including seventy-eight BATC colors and fi…
Spectral energy distributions and age estimates of 104 M31 globular clusters
Song Wang, Zhou Fan, Jun Ma +2
We present photometry of 104 M31 globular clusters (GCs) and GC candidates in 15 intermediate-band filters of the Beijing-Arizona-Taiwan-Connecticut (BATC) photometric system. The…
