Stellar atmospheric parameters of 11,000 RR Lyrae stars from LAMOST Spectra
Jiangtao Wang, Jianrong Shi, Jianning Fu +2
Accurate determination of the stellar atmospheric parameters of RR Lyrae stars (RRLs) requires short individual exposures of the spectra to mitigate pulsation effects. We present i…
An X-Ray-dim "Isolated'' Neutron Star in a Binary?
Jie Lin, Chunqian Li, Weiyang Wang +13
We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modelling of th…
The Nearest Neutron Star Candidate in a Binary Revealed by Optical Time-domain Surveys
Ling-Lin Zheng, Mouyuan Sun, Wei-Min Gu +19
The near-Earth (within pc) supernova explosions in the past several million years can cause the global deposition of radioactive elements (e.g., Fe) on Earth. The…
A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
A long-period pre-ELM system discovered from LAMOST medium-resolution survey
Zhi-Xiang Zhang, Ling-Lin Zheng, Wei-Min Gu +16
We present LAMOST~J041920.07+072545.4 (hereafter J0419), a close binary consisting of a bloated extremely low mass pre-white dwarf (pre-ELM WD) and a compact object with an orbital…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
Mass-Ratio Distribution of Binaries From the LAMOST-MRS Survey
Jiangdan Li, Jiao Li, Chao Liu +7
Binary evolution leads to the formation of important objects crucial to the development of astrophysics, but the statistical properties of binary populations are still poorly under…
Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8
Ming-Yi Ding, Jian-Rong Shi, Yue Wu +9
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derive…
Spot and Facula Activity Variations of the Eccentric Detached Eclipsing Binary KIC 8098300 Based on the Time-series Orbital Solutions
Hubiao Niu, Jianning Fu, Jiaxin Wang +1
The LAMOST spectra and light curves are combined to investigate the detached eclipsing binary KIC 8098300, which shows the O'Connell effect caused by spot/facula modu…
LAMOST Time-Domain Survey: First Results of four 2 plates
Song Wang, Haotong Zhang, Zhongrui Bai +23
From Oct. 2019 to Apr. 2020, LAMOST performs a time-domain spectroscopic survey of four 2 plates with both low- and med-resolution observations. The low-resolution spectroscopic…
Double-, triple-line spectroscopic candidates in the LAMOST Medium-Resolution Spectroscopic Survey
Chun-qian Li, Jian-rong Shi, Hong-liang Yan +3
The LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS) provides an unprecedented opportunity for detecting multi-line spectroscopic systems. Based on the method of Cross-Co…
Lithium Evolution of Giant Stars Observed by LAMOST and Kepler
Jinghua Zhang, Jian-Rong Shi, Hong-Liang Yan +8
Mapping lithium evolution for evolved stars will provide restrictions and constraints on the fundamental stellar interior physical processes, which further shed light on our unders…
The Lithium Abundances from the Large Sky Area Multi-object Fiber Spectroscopic Telescope Medium-resolution Survey. I. The Method
Qi Gao, Jian-Rong Shi, Hong-Liang Yan +9
Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge-up process (FDU). Yet a small fraction of giant stars are still found…
Searching for r-process-enhanced stars in the LAMOST Survey I: The Method
Tian-Yi Chen, Jian-Rong Shi, Timothy C. Beers +5
The abundance patterns of -process-enhanced stars contain key information required to constrain the astrophysical site(s) of -process nucleosynthesis, and to deepen our under…
Lithium-rich Giants in LAMOST Survey. I. The Catalog
Qi Gao, Jian-Rong Shi, Hong-Liang Yan +5
