Estimating stellar atmospheric parameters, absolute magnitudes and elemental abundances from the LAMOST spectra with Kernel-based Principal Component Analysis
Maosheng Xiang, Xiaowei Liu, Jianrong Shi +16
Accurate determination of stellar atmospheric parameters and elemental abundances is crucial for Galactic archeology via large-scale spectroscopic surveys. In this paper, we estima…
Constraining the Galactic structure parameters with the XSTPS-GAC and SDSS photometric surveys
Bingqiu Chen, Xiaowei Liu, Haibo Yuan +7
Photometric data from the Xuyi Schmidt Telescope Photometric Survey of the Galactic Anticentre (XSTPS-GAC) and the Sloan Digital Sky Survey (SDSS) are used to derive the global str…
Distance and extinction determination for APOGEE stars with Bayesian method
Jianling Wang, Jianrong Shi, Kaike Pan +3
Using a Bayesian technology we derived distances and extinctions for over 100,000 red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) su…
The Milky Way's rotation curve out to 100 kpc and its constraint on the Galactic mass distribution
Yang Huang, Xiaowei Liu, Haibo Yuan +9
The rotation curve (RC) of the Milky Way out to 100 kpc has been constructed using 16,000 primary red clump giants (PRCGs) in the outer disk selected from the LSS-GAC…
