AS 373
AS 373, also known as V1016 Cygni, is a symbiotic nova in Cygnus, a binary of a Mira variable and a white dwarf that brightened nearly 5 magnitudes in 1964.
Classical nova
A classical nova is a thermonuclear eruption of accreted hydrogen on a white dwarf's surface in a binary system, brightening it without destroying either star.
Micronova
A micronova is a localized thermonuclear explosion on a white dwarf's surface, roughly a million times weaker than a nova and lasting only hours, first reported in 2022.
Nova
A nova, or stellar nova, is a thermonuclear eruption on a white dwarf star that brightens up to hundreds of thousands of times the Sun's luminosity.
Recurrent nova
A recurrent nova is a cataclysmic binary system containing a white dwarf that undergoes nova eruptions more than once, with recurrence times of about 1 to 100 years.
RR Telescopii
RR Telescopii (RR Tel) is a symbiotic nova in the southern constellation Telescopium, an interacting binary in which a white dwarf accretes from a Mira variable that erupted in 1944.
RS Ophiuchi
RS Ophiuchi is a recurrent nova in the constellation Ophiuchus, a binary of a massive white dwarf accreting from a red giant that erupts roughly every 15 years.
T Coronae Borealis
T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a recurrent nova system in Corona Borealis that erupts roughly every 80 years, recorded in 1866 and 1946.
U Scorpii
U Scorpii is a recurrent nova in the constellation Scorpius, a binary system whose white dwarf suffers thermonuclear eruptions about every ten years, most recently in 2022.
V1500 Cygni
V1500 Cygni, also cataloged as Nova Cygni 1975, is a bright nova that erupted in Cygnus in August 1975 and became the first known asynchronous polar.
V1974 Cygni
V1974 Cygni (Nova Cygni 1992) is a fast classical nova in Cygnus that erupted in 1992, peaking at magnitude 4.4 as the brightest nova since 1975.
V603 Aquilae
V603 Aquilae, also known as Nova Aquilae 1918, is a classical nova in Aquila that erupted in June 1918 and briefly rivaled Vega in brightness.
