WD mass–radius relations for different effective temperatures of the hydrogen envelope (Fontaine et al. 2001). The relation suggested by Nauenberg (1972) for zero temperature WDs is shown with the dashed black curve. The dashed blue curve is the fit for 50 kK envelope temperature, see Eq. (14) and Table 2.
