Magnetic-field constraints for four magnetic cataclysmic variables from simultaneous continuum and cyclotron modeling
Jiamao Lin, Wenyuan Guo, Yongkang Sun +2
their fields are rarely measured because cyclotron humps must be separated from uncertain continua and assigned to discrete harmonics. We applied a simultaneous continuum-cyclotron…
KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasi-periodic Out-of-eclipse Modulations

To study the quality of stellar spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and the correctness of the corresponding stellar parameters derive…
A catalog of early-type Hα emission line stars and 58 newly confirmed Herbig Ae/Bes from LAMOST DR7
Yun-Jun Zhang, Wen Hou, A-Li Luo +6
We derive a catalog of early-type emission-line stars including 30,048 spectra of 25,886 stars from LAMOST DR7, in which 3,922 have Simbad records. The sample is obtained using K-N…
Rotational Velocities of Am and Non-CP Stars based on Kepler and LAMOST DR5
Li Qin, A-Li Luo, Wen Hou +9
Rotation is a critical physical process operating in the formation of Am stars. There is a strong correlation between low-velocity rotation and chemical peculiarity. However, the e…
