GK Vir is a detached eclipsing binary system con- sisting of a white dwarf (WD – primary) and a low- mass main-sequence star (secondary) with an orbital period of 8.27 h
The component masses and radii are M_WD = 0.564 M_Sun , M_sec= 0.116 M_Sun and R_WD = 0.0170 R_Sun , R _sec = 0.155 R_Sun (Almeida et al. 2020).
Here the mass given is the sum of the component masses.
