Définition

  • A U Geminorum-type variable star, or dwarf nova (pl. novae) is one of several types of cataclysmic variable star, consisting of a close binary star system in which one of the components is a white dwarf that accretes matter from its companion. Dwarf novae are dimmer and repeat more frequently than "classical" novae. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Dwarf_nova)
