Extended Tidal Tails of IC 4756 detected by {\it Gaia} EDR3
Xianhao Ye, Jinkun Zhao, Jiajun Zhang +2
We report the discovery of emerged tidal tails around open cluster IC 4756 ( 1 Gyr) based on 644 members identified from {\it Gaia} EDR3. Three-dimensional spatial positions,…
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…
