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…
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…
Characterising galaxy cluster scaling relations as cosmic isotropy tracers using FLAMINGO simulations
Yujie He, Konstantinos Migkas, Joop Schaye +2
The standard cosmological model, CDM, assumes isotropy on large cosmic scales. However, recent studies using galaxy cluster scaling relations have reported an apparent ani…
LAMOST J171013+532646: a detached short-period non-eclipsing hot subdwarf + white dwarf binary
Mingkuan Yang, Hailong Yuan, Zhongrui Bai +9
We present an analysis of LAMOST J171013.211+532646.04 (hereafter J1710), a binary system comprising a hot subdwarf B star (sdB) and a white dwarf (WD) companion. Multi-epoch spect…
Near-Infrared Ca II Triplet As An Stellar Activity Indicator: Library and Comparative Study
Xin Huang, Yu-JI He, ZhongRui Bai +11
We have established and released a new stellar index library of the Ca II Triplet, which serves as an indicator for characterizing the chromospheric activity of stars. The library…
Orbital parameters for an ELM white dwarf with a white dwarf companion: LAMOST J033847.06+413424.2
Hailong Yuan, Zhenwei Li, Zhongrui Bai +14
Double white dwarf systems are of great astrophysical importance in the field of gravitational wave and Type Ia supernova. While the binary fraction of CO core white dwarf is about…
