kataklüsmiline muutlik täht, milles noova plahvatused korduvad 10-100 aasta järel
novae that have been observed to undergo outbursts more than once, resulting from runaway nuclear burning of hydrogen-rich material accreted onto a white dwarf from its binary companion
Our nearest galactic neighbor, Andromeda, hosts the most rapid recurrent novae observed to date, including the shortest-period known recurrent nova, M31N 2008-12a. M31N 2008-12a has erupted once a year for millions of years and will eventually meet its fate in a supernova explosion.
