nova
Définition(s)
- A nova is a type of cataclysmic binary that undergoes a sudden, spectacular brightening, by a factor of up to a million or so, before dimming to its pre-nova state. Far from being "new" stars, as their historical name suggests, novae consist of a white dwarf primary in close orbit around an orange or red dwarf or (in some cases) giant secondary, the fuel for the outbursts being gas plundered from the larger star by the white dwarf. (Encyclopedia of Science, by David Darling, https://www.daviddarling.info/encyclopedia/N/nova.html)
