Discovery and Characterization of White Dwarf-FGK Main-Sequence Binaries within the Optical Main-Sequence Locus

Mingkuan Yang, Hailong Yuan, Xiaozhen Yang +12

White dwarf main-sequence (WDMS) binaries provide important laboratories for studying binary evolution and the formation of low-mass white dwarfs. In this work, we identify 654 rel…

Revisiting Ca II Activity Indices in FGK Stars: Systematic Biases in Infrared Triplet Measurements

Xiaozhen Yang, Xiaoting Fu, Mingjie Jian +10

Synthetic-template subtraction is widely used to measure chromospheric activity in large spectroscopic surveys. However, many solar-like FGK stars show systematically negative Ca I…

Searching for Magnetic White Dwarfs in LAMOST DR10

Si-Cheng Yu, Juan-Juan Ren, Vitaly V. Neustroev +7

Magnetic white dwarfs (MWDs) are key to understanding the origin and evolution of magnetic fields in compact stars. While large spectroscopic surveys such as SDSS have greatly expa…

Weighing Hidden Companions of Compact Object Candidates via Rotational Broadening

Rui Wang, Zhi-Xiang Zhang, Wei-Min Gu +3

The determination of unseen companion masses () is essential for identifying compact objects in binary systems, yet obtaining reliable orbital inclinations remains one of the…

The size-velocity dispersion relationship of Galactic HII regions

Lin Ma, Yunning Zhao, Wei Zhang +11

The size-velocity dispersion () relation, while well established for giant HII regions, remains uncertain for their smaller counterparts (physical radii R < 20 pc). Thanks to th…

The survey of DA double white dwarf candidates based on DESI EDR

Ziyue Jiang, Hailong Yuan, Zhongrui Bai +9

Mergers of double white dwarfs are considered significant potential progenitors of type Ia supernovae. Although there is no direct observational evidence to definitively determine…
