Empirical colour--effective temperature relations in the SDSS system from IRFM temperatures of GALAH and APOGEE stars
Zenghua Zhou, Luca Casagrande, Xiaobin Zhang +5
Reliable estimates of stellar effective temperature () are fundamental to stellar population studies and Galactic astrophysics. However, the majority of stars ob…
Identification of false positive double-lined spectroscopic binaries in LAMOST-MRS data due to moonlight contamination
Zhoulin Wang, Mikhail Kovalev, Jianping Xiong +2
We present a method for identifying false positive double-lined spectroscopic binary (SB2) candidates by analysing medium-resolution survey spectra from the Large Sky Area Multi-Ob…
The origin of B-type runaway stars based on kinematics
Yanjun Guo, Chao Liu, ZhiCun Liu +5
Runaway stars depart their birthplaces with high peculiar velocities. Two mechanisms are commonly invoked to explain their origin, the binary supernova scenario (BSS) and the dynam…
The binary fraction of Blue Horizontal-Branch (BHB) Stars
Yanjun Guo, Kun Chen, Zhenwei Li +6
Blue horizontal-branch (BHB) stars are old, low-mass, metal-poor stars that serve as important tracers of the Galactic halo structure, kinematics, and evolution.Understanding their…
The Binary Fraction of B-type Runaway Stars from LAMOST DR8
Kun Chen, Yanjun Guo, Dengkai Jiang +2
Runaway stars are defined as stars that depart from their birth clusters at high peculiar velocities. There are two main mechanisms for the formation of runaway stars, i.e., the bi…
NLTE abundances of Eu for a sample of metal-poor stars in the Galactic Halo and Metal-poor Disk with 1D and <3D> models
Yanjun Guo, Nicholas Storm, Maria Bergemann +6
Accurate measurements of europium abundances in cool stars are essential for an enhanced understanding of the r-process mechanisms. We measure the abundance of Eu in solar spectra…
