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 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…
Detecting shock waves in non-fundamental mode RR Lyrae using large sample of spectra in SDSS and LAMOST
Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4
Steps toward the nature inside RR Lyrae variables can not only improve our understanding of variable stars but also innovate the precision when we use them as tracers to map the st…
On the radial velocity calibrations in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Juan-Juan Ren, Hong Wu, Chao-Jian Wu +12
Accurate radial velocity determinations of optical emission lines (i.e. [NII]6548,6584, H, and [SII]6717,6731) are very important for investigating the kinematics and dy…
A Catalog of Short Period Spectroscopic and Eclipsing Binaries Identified from the LAMOST & PTF Surveys
Fan Yang, Richard J. Long, Su-Su Shan +7
Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information, taking…
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…
Irregular changes in Hα emission line of V423 Aur observed by LAMOST Medium-Resolution Spectrographs
Chao-Jian Wu, Hong Wu, Chih-Hao Hsia +8
We obtained 7 spectra of the Be star V423 Aur on Dec. 5th, 2017 using the LAMOST Medium-Resolution Spectrograph with exposures from 600 to 1200 seconds. These spectra show the irre…
Searching for Black Hole Candidates by LAMOST and ASAS-SN
Ling-Lin Zheng, Wei-Min Gu, Tuan Yi +13
Most dynamically confirmed stellar-mass black holes and the candidates were originally selected from X-ray outbursts. In the present work, we search for black hole candidates in th…
Long rotation period main-sequence stars from Kepler SAP light curves
Kaiming Cui, Jifeng Liu, Shuhong Yang +7
Stellar rotation plays a key role in stellar activity. The rotation period could be detected through light curve variations caused by starspots. Kepler provides two types of light…
FGK 22 m Excess Stars in LAMOST DR2 Stellar Catalog
Chao-Jian Wu, Hong Wu, Kang Liu +8
Since the release of LAMOST (the Large Sky Area Multi-Object Fiber Spectroscopic Telescope) catalog, we have the opportunity to use the LAMOST DR2 stellar catalog and \emph{WISE Al…
Member candidates of the star clusters from LAMOST DR2 data
Bo Zhang, Xiao-Yan Chen, Chao Liu +10
In this work, we provide 2189 photometric- and kinematic-selected member candidates of 24 star clusters from the LAMOST DR2 catalog. We perform two-step membership identification:…
DA white dwarfs observed in LAMOST pilot survey
Yue-Yang Zhang, Li-Cai Deng, Chao Liu +14
A total of objects from LAMOST pilot survey have been publicly released. In this work, we present a catalog of DA white dwarfs from the entire pilot survey. We outlin…
