Samenvatting

Algol binaries show a well defined distribution of orbital periods and mass ratios. The distribution of mass ratios can however not be obtained by conservative binary evolution only. Many progenitors of Algols lose some mass and little angular momentum during short phases of rapid Roche Lobe Overflow. Rapid rotational velocity caused by spin-up of the gainer combines with accretion luminosity in a hot spot. The energies of both effects together may overcome the binding energy of matter in the hot spot during a short era of rapid RLOF. As a consequence Algols will remain in a state of high mass ratio for a longer time as required by the observations.
