  skos:definition "Une (étoile) variable cataclysmique (CV en anglais) est un type d'étoile binaire. Elle est constituée de deux étoiles : une primaire naine blanche, et une secondaire lui transférant sa masse. On connait actuellement plus de 1600 systèmes CV. Elles ont une période orbitale comprise typiquement entre 80 minutes et 12 heures, bien qu'il y ait une lacune statistique entre 2 et 3 heures dans la distribution des périodes observées. (Wikipedia, L'Encylopédie Libre, <a href=\"https://fr.wikipedia.org/wiki/Variable_cataclysmique\" target=\"_blank\">https://fr.wikipedia.org/wiki/Variable_cataclysmique</a>)"@fr, "A variable star that shows a sudden and dramatic change in brightness, including flare stars, novae, and some types of symbiotic stars. They are believed to be very close binary systems consisting of an accreting white dwar primary and an evolved late-type secondary star that has filled its Roche lobe. For systems with an accretion disk, it is believed that a thermal instability is the cause of repetitive outbursts observed in cataclysmic variables called dwarf novae.
