Spectroscopically Identified Cataclysmic Variables from LAMOST survey. I. The Sample
Wen Hou, A-Li Luo, Yin-Bi Li +1
A sample of Cataclysmic Variables (CVs) is presented including spectroscopically identified 380 spectra of 245 objects, of which 58 CV candidates are new discoveries. The BaggingTo…
Properties of Radial Velocities measurement based on LAMOST-II Medium-Resolution Spectroscopic Observations
R. Wang, A. -L. Luo, J. -J. Chen +28
The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolu…
Bivariate Luminosity Function of Galaxy Pairs
Shuai Feng, Shi-Yin Shen, Fang-Ting Yuan +8
We measure the bivariate luminosity function (BLF) of galaxy pairs and use it to probe and characterize the galaxy-galaxy interaction between pair members. The galaxy pair sample i…
Metallic-Line Stars Identified from Low Resolution Spectra of LAMOST DR5
Li Qin, A-Li Luo, Wen Hou +6
LAMOST DR5 released more than 200,000 low resolution spectra of early-type stars with S/N>50. Searching for metallic-line (Am) stars in such a large database and study of their sta…
Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: A pointing towards the Kepler field
Nian Liu, Jian-Ning Fu, Weikai Zong +20
Radial velocity is one of key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field were observed…
