The evolution and structure of a slow deflagration front propagating into a cool hydrogen-rich shell above an inert core is analyzed in order to point out a possible mechanism for the radiant-energy source of a white dwarf. It is shown that, as viewed by an observer moving with the deflagration front, matter enters the front with a finite velocity, accelerates somewhat, and then decelerates to a finite velocity equal to the initial velocity. Calculations indicate that the outward radiation from the front is typically of the order of 100 to 1000 suns for an evolutionary time scale of the order of 100 yr and drops to a value of 0.01 to 0.0001 sun when the time scale is of the order of 10 million to 1 billion yr. Possible implications of this model are discussed.
