One of the remaining issues in the problems of dwarf novae is whether or not enhanced mass transfer due to irradiation of the secondary stars could occur during outbursts.
Enhanced mass transfer during dwarf nova outbursts by irradiation of the secondary?
Furthermore, we have presented a theoretical analysis which shows that irradiation during outburst should not affect the mass transfer rate.
Enhanced mass transfer during dwarf nova outbursts by irradiation of the secondary?
Unequal irradiation then causes fluid flow over the surface of the secondary.
Enhanced mass transfer during dwarf nova outbursts by irradiation of the secondary?
Since the depth of the zone affected by irradiation (which we denote by D) is limited to a sub-surface zone a few scale heights deep, we have D ≪ R, where R is the stellar radius.
