Mass distribution for single-lined hot subdwarf stars in LAMOST
Zhenxin Lei, Ruijie He, Peter Nemeth +4
Masses for 664 single-lined hot subdwarf stars identified in LAMOST were calculated by comparing synthetic fluxes from spectral energy distribution (SED) with observed fluxes from…
Properties and Asteroseismological analysis of a new ZZ ceti discovered by TMTS
Jincheng Guo, Yanhui Chen, Xiaofeng Wang +24
Tsinghua university-Ma Huateng Telescope for Survey (TMTS) aims to discover rapidly evolving transients by monitoring the northern sky. The TMTS catalog is cross-matched with the w…
At what mass are stars braked? The implication from the turnoff morphology of NGC 6819
Yong Yang, Chengyuan Li, Yang Huang +1
Extended main-sequence turnoffs apparent in most young and intermediate-age clusters (younger than ~2 Gyr) are known features caused by fast rotating early-type (earlier than F-typ…
White dwarfs identified in LAMOST Data Release 5
Jincheng Guo, Jingkun Zhao, Huawei Zhang +5
In this paper, we report white dwarfs identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope, including spectral types of DA, DB, DC, DZ, a…
LAMOST J0140355+392651: An evolved cataclysmic variable donor transitioning to become an extremely low mass white dwarf
Kareem El-Badry, Eliot Quataert, Hans-Walter Rix +6
We present LAMOST J0140355+392651 (hereafter J0140), a close ( hours) binary containing a bloated, low-mass () proto-white dwarf (WD)…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
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…
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…
Ages and masses of million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic spectroscopic surveys
Maosheng Xiang, Xiaowei Liu, Jianrong Shi +10
We present estimates of stellar age and mass for 0.93 million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic Spectroscopic Surveys. The ages and…
