A search for open cluster Cepheids in the Galactic plane
Xiaodian Chen, Richard de Grijs, Licai Deng
We analyse all potential combinations of Galactic Cepheids and open clusters (OCs) in the most up-to-date catalogues available. Isochrone fitting and proper-motion calcula- tion ar…
Fixing the Reference Frame for PPMXL Proper Motions Using Extragalactic Sources
Kathleen Grabowski, Jeffrey L. Carlin, Heidi Jo Newberg +14
We quantify and correct systematic errors in PPMXL proper motions using extragalactic sources from the first two LAMOST data releases and the Veron-Cetty & Veron Catalog of Quasars…
Comparing the Host Galaxies of Type Ia, Type II and Type Ibc Supernovae
X. Shao, Y. C. Liang, M. Dennefeld +8
We compare the host galaxies of 902 supernovae, including SNe Ia, SNe II and SNe Ibc, which are selected by cross-matching the Asiago Supernova Catalog with the SDSS Data Release 7…
The binarity of Milky Way F,G,K stars as a function of effective temperature and metallicity
Shuang Gao, Chao Liu, Xiaobin Zhang +3
We estimate the fraction of F,G,K stars with close binary companions by analysing multi-epoch stellar spectra from SDSS and LAMOST for radial velocity (RV) variations. We employ a…
The Nearest High-Velocity Stars Revealed by LAMOST Data Release 1
Jing Zhong, Li Chen, Chao Liu +14
We report the discovery of 28 candidate high-velocity stars (HVSs) at heliocentric distances of less than 3 kpc, based on the Large Sky Area Multi-Object Fiber Spectroscopic Telesc…
The K giant stars from the LAMOST survey data I: identification, metallicity, and distance
Chao Liu, Li-Cai Deng, Jeffrey L. Carlin +10
We present a support vector machine classifier to identify the K giant stars from the LAMOST survey directly using their spectral line features. The completeness of the identificat…
The First Hypervelocity Star from the LAMOST Survey
Zheng Zheng, Jeffrey L. Carlin, Timothy C. Beers +10
We report the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey. It is a B-type star with a heliocentric radial velocity about 620 km/s, which projects…
