| Summary: | I investigate variations of the mass transfer rate in cataclysmic variables (CVs) induced by nova outbursts. The ballistic ejection of nova shells leads to a spectrum of observed transfer rates in a sample of systems with similar orbital period. I present an analytical model and show that the effect is negligible below the period gap and for CVs with high-mass white dwarfs. If the orbital period is longer than 3 hr, the mass transfer rate spectrum has an effective width in excess of an order of magnitude provided the mass accreted on the white dwarf prior to the runaway is in excess of a few 10(-4) M.. |
