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…
