We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
A long-period pre-ELM system discovered from LAMOST medium-resolution survey
Zhi-Xiang Zhang, Ling-Lin Zheng, Wei-Min Gu +16
We present LAMOST~J041920.07+072545.4 (hereafter J0419), a close binary consisting of a bloated extremely low mass pre-white dwarf (pre-ELM WD) and a compact object with an orbital…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
