Five-colour optical photometry of AE Aquarii.

J. van Paradijs, H. Kraakman, S. van Amerongen

Abstract

Les observations photometriques 5 couleurs effectuees en 1984 et 1985 sont rapportees pour la variable cataclysmique AE Aqr. Les resultats de la photometrie montrent que 2 composantes peuvent etre distinguees dans les variations de la brillance optique: une courbe de lumiere ellipsoidale reguliere due a la deformation de la secondaire de type K et des eruptions irregulieres dues aux instabilites dans l'ecoulement d'accretion sur la naine blanche
