Dwarf nova outbursts. IV. Absolute magnitudes at maximum

Absolute visual magnitudes and bolometric luminosities at maximum, calculat ed from models of dwarf nova outbursts, are practically identical with thos e corresponding to the steady-state accretion at the critical mass transfer fate. This is due to the fact that the temperature distribution in the inn er parts of the disk, which contribute most of the global flux, matches clo sely the standard, steady-state distribution. The theoretical M-V(max) = f(M-1,P) relations reproduce, on the average, qu ite well the observed M-V vs. P relation. Observational data appear insuffi cient, however, to confirm the predicted dependence on M-1.
