NGC 1893: a young open cluster rich in multi-type variable stars
Hui-Fang Xue, Jian-Ning Fu, Nami Mowlavi +4
In this work, we have studied the variable stars in the young open cluster NGC 1893 based on a multi-year photometric survey covering a sky area around the cluster up to $31' \time…
LAMOST observations in the Kepler field. II. Database of the low-resolution spectra from the five-year regular survey
Weikai Zong, Jian-Ning Fu, Peter De Cat +19
The LAMOST-Kepler (LK-) project was initiated to use the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) to make spectroscopic follow-up observations for the tar…
Are the silicate crystallinities of oxygen-rich evolved stars related to their mass loss rates?
Biwei Jiang, Jiaming Liu, Aigen Li
A sample of 28 oxygen-rich evolved stars is selected based on the presence of crystalline silicate emission features in their ISO/SWS spectra. The crystallinity, measured as the fl…
The nature of the Li enrichment in the most Li-rich giant star
Hong-Liang Yan, Jian-Rong Shi, Yu-Tao Zhou +13
About one percent of giants\upcite{Brown1989} are detected to have anomalously high lithium (Li) abundances in their atmospheres, conflicting directly with the prediction of the st…
Variability survey in NGC 6910, the open cluster rich in Cephei-type stars
D. Moździerski, A. Pigulski, Z. Kołaczkowski +14
NGC 6910 is the northern hemisphere open cluster known to be rich in Cephei-type stars. Using four-season photometry obtained in Białków (Poland) and Xinglong (China) observato…
Photometric and spectroscopic observations of the neglected near-contact binary Cl* Melotte 111 AV 1224
L. Fox-Machado, T. Q. Cang, R. Michel +2
This paper presents a photometric and spectroscopic study of the short-period binary star Cl*~Melotte~111~AV~1224. Measurements in the , , and passbands obtained during t…
LEMONY--a Library of Empirical Medium-resolution spectra by Observations with the NAOC Xinglong 2.16\,m and YNAO Gaomeigu 2.4\,m telescopes
Chun Wang, Xiaowei Liu, Yang Huang +15
This study expands the coverage and improves the homogeneity of the distribution of MILES template stars in the parameter space, as well as extends the wavelength coverage of the t…
Asteroseismology of the Double-Mode High-Amplitude Scuti Star VX Hydrae
Hui-Fang Xue, Jian-Ning Fu, L. Fox-Machado +11
Bi-site time-series photometric and high-resolution spectroscopic observations were made for the double-mode high-amplitude Scuti star VX\ Hya. The fundamental frequency $f_{0}…
A new catalogue of radial velocity standard stars from the APOGEE data
Yang Huang, Xiaowei Liu, Bingqiu Chen +5
We present a new catalogue of 18 080 radial velocity standard stars selected from the APOGEE data. These RV standard stars are observed at least three times and have a median stabi…
Estimating The Mean Linewidth And Lifetime of Solar-like Oscillations of Stars
Wuming Yang
\textbf{Scaling formulas were} deduced to describe the relations between the fundamental stellar parameters and the mean \textbf{linewidth and lifetime} of solar-like oscillations…
The Ultraviolet Extinction in the Bands
Mingxu Sun, B. W. Jiang, He Zhao +4
Interstellar extinction in ultraviolet is the most severe in comparison with optical and infrared wavebands and a precise determination plays an important role in correctly recover…
Formation of the Abundance Boundaries of the Heavier Neutron-capture Elements in Metal-poor Stars
Guochao Yang, Hongjie Li, Nian Liu +5
The abundance scatter of heavier r-process elements (Z > 56) relative to Fe ([r/Fe]) in metal-poor stars preserves excellent information of the star formation history and provides…
The Effects of Binary Stars on the Color-Magnitude Diagrams of Young-Age Massive Star Clusters
Wuming Yang
Extended main-sequence turnoffs (eMSTO) have been observed in the color-magnitude diagram (CMD) of intermediate-age and young star clusters. The origin of the eMSTO phenomenon is s…
Probing the 9.7μm Interstellar Silicate Extinction Profile through the Spitzer/IRS Spectroscopy of OB Stars
Z. Z. Shao, B. W. Jiang, Aigen Li +3
The 9.7m interstellar spectral feature, arising from the Si--O stretch of amorphous silicate dust, is the strongest extinction feature in the infrared (IR). In principle, the sp…
Red supergiant stars in the Large Magellanic Cloud. II. Infrared properties and mid-infrared variability
Ming Yang, Alceste Z. Bonanos, Bi-Wei Jiang +7
The characteristics of IR properties and MIR variability of RSGs in the LMC are analyzed based on 12 bands of NIR to MIR co-added data from 2MASS, Spitzer and WISE, and 6.6 y…
Binary Star Fractions from the LAMOST DR4
Zhijia Tian, Xiaowei Liu, Haibo Yuan +17
Stellar systems composed of single, double, triple or high-order systems are rightfully regarded as the fundamental building blocks of the Milky Way. Binary stars play an important…
Misclassified B stars in the Kepler field
Chunguang Zhang, Chao Liu, Yue Wu +7
