Comparisons of Different Fitting Methods for the Physical Parameters of A Star Cluster Sample of M33 with Spectroscopy and Photometry

Zhou Fan, Bingqiu Chen, Xiaoying Pang +8

Star clusters are good tracers for formation and evolution of galaxies. We compared different fitting methods by using spectra (or by combining photometry) to determine the physica…

An extremely hot white dwarf with a rapidly rotating K-type subgiant companion: UCAC2 46706450

Klaus Werner, Nicole Reindl, Lisa Löbling +5

UCAC2 46706450 is a late-type star with an ultraviolet (UV) excess. It was considered a candidate to establish a sample of FGK stars with white dwarf (WD) companions that can be us…

LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS): Scientific goals and survey plan

Chao Liu, Jianning Fu, Jianrong Shi +38

Since September 2018, LAMOST starts a new 5-year medium-resolution spectroscopic survey (MRS) using bright/gray nights. We present the scientific goals of LAMOST-MRS and propose a…
