A Massive White Dwarf or Low-mass Neutron Star Discovered by LAMOST

A Massive White Dwarf or Low-mass Neutron Star Discovered by LAMOST

We report the discovery of a close binary J0606+2132 (Gaia DR3 3423365496448406272) with P _obs = 2.77 days containing a possible massive white dwarf (WD) or a neutron star (NS) using LAMOST spectroscopic data. By a joint fitting of the radial velocity from LAMOST and the light curve from TESS, we d...
