Color map of the hydrogen mass for the MRR obtained at different effective temperatures, from 10 kK to 60 kK. Theoretical curves from Panei et al. (2000) are plotted for comparison. The green (dashed) lines correspond to Helium WDs of (from left to right) 4.0, 8.0, 12.0, 16.0, and 20.0 kK with the same hydrogen layer. The light blue (point-dashed) lines correspond to carbon WDs of (from left to right) 5.0, 15.0, 25.0, 35.0, 45.0, 55.0, 70.0, 85.0, and 100.0 kK with the same hydrogen and helium layers.
