NOVA AQUILAE 1999
Nova Aquilae 1999, 13,000 light years away, shines to the right of the bright star Altair. Altair and its flanking stars Alshain and Tarazed are at the left edge of the picture. The bright star at far right is Delta Aquilae.

Nova result from the accretion of hydrogen onto a white dwarf star from a companion body, which subsequently ignites and causes runaway nuclear fusion.
Recurrent Nova
A recurrent nova is a which has been observed to have multiple outbursts. In the case of recurrent novae and , a shell of ejected matter can be detected spectroscopically, while exhibit no such behavior.

The Answer
I don't know the answer to your question, but there are several types of things called 'nova'.
Nova
The above discussion applies to the evolution of a single star. In a binary system, situations may become more complicated.
Nova or new star
This theory, that the Magi saw a nova or supernova explosion, was hinted at by Kepler and has had many supporters since then.
nova A star that suddenly increases in brightness, often by a factor of as much as 10,000, then slowly fades back to its original luminosity.
nova
an explosion on the surface of a white dwarf that is accreting matter from a companion star, which causes the system to temporarily brighten by a factor of several hundred to several thousand
nuclear fusion ...
Nova: A star that abruptly and temporarily increases its brightness by a factor of hundreds of thousands. Unlike supernovae (much more violent explosions which destroy the stars that produce them), stars that "go nova'' can do so more than once.

Nova
(a) A star that brightens suddenly and to an unprecedented degree, creating the impression that a new star has appeared where none was before. Hence the name, from nova for "new". see Supernova ...

Nova
From Latin meaning "new"; a sudden brightening of a star, making it appear as a new star in the sky; believed associated with eruptions on white dwarfs in binary systems.

Nova
a star that flares up to several times its original brightness for some time before returning to its original state.
Nova. A star that suddenly flares up to several times its normal brightness. Typically they remain bright for a short period before fading back into obscurity.

Nova explosions eject matter from a white dwarf's surface, but they do not necessarily expel or burn all the material that has accumulated since the last outburst.

NOVA
A nova is a that suddenly increases in brightness by several magnitudes. It fades very slowly.
NUCLEAR BULGE
The nuclear bulge is the central, spherical part of a spiral galaxy. It is surrounded by a disk-shaped mass of stars with spiral arms.

The name "nova" means "new" in Latin. In astronomy it's used to describe an object that suddenly shines much more brightly than it had before.
Astronomia nova
The extended line of research that culminated in Astronomia nova (A New Astronomy) —including the first two laws of planetary motion—began with the analysis, under Tycho's direction, of Mars' orbit.
GK Persei, or Nova Persei 1901, was one of the brightest novae in modern times. It occurred in 1901, about 1,500 light-years away.
Nova Cygni seen at two different times, 1992 and 1993 (left and right respectively). The expansion of the blast shell over time is obvious in the two images. The two stars that are the source of the nova appear like one star in the middle.
[10] Tycho's nova had right ascension RA = 0 h, 22 m, declination d = 63° 53'. Look up a star chart--in which constellation did it occur?
[edit] A nearby nova, supernova or gamma ray burst
A nearby gamma ray burst (fewer than 6000 light years away) could sufficiently irradiate the surface of Earth to kill organisms living there and destroy the ozone layer in the process.

Eventually gravitation pulls the remains of a super nova explosion together and it begins to contract. To understand what happens next we have to know a bit about the structure of an atom.
The most spectacular variable is the so-called temporary star, or nova.
One of these is the nova, characterized by an abrupt increase in brightness but only by a factor of a million (as opposed to 100 million in a supernova). A nova is caused by hydrogen accreted onto the surface of the white dwarf.
(See Kepler's theory of the solar system.) In his Astronomia Nova ("New Astronomy") of 1609, Kepler had demonstrated that the orbit of the planet Mars is an ellipse.
(It had appeared on October 9 previous.) The appearance of the star, which Kepler described in his book De Stella nova in pede Serpentarii, provided further evidence that the cosmos was not changeless; this was to influence Galileo's argument.

An intermediate stage in the transition from classical to scientific mapping was the Uranometria Nova of the German astronomer F. W. A. Argelander published in 1843.
A Dutch astronomer, David Fabricus, considered it a nova in 1596. It wasn't remarked on again until 1603, when Bayer put it in his catalogue under the name omicron. He apparently had stumbled across the star at one of its maximums.
The orbit of any protoplanet forming around Sirius A at that distance could have been disrupted by the close orbit of Sirius B, and also probably during B's mass loss when it became a nova then a white dwarf.
RS Ophiuchi es un tipo de estrella llamada nova recurrente. Estos raros objetos permanecen opacas por largos períodos de tiempo y de pronto vuelven a brillar. Por lo general, RS es una estrella de magnitud 11, pero en 1958 alcanzó una magnitud de 5.
Kepler’s "Astonomia nova" contains his views that the planets orbit the Sun in ellipses, sweeping out equal angles in equal time intervals (Kepler’s Law).

These instabilities cause material to be dumped more rapidly onto the white dwarf resulting in the release of large amounts of gravitational energy -- the nova outburst.
He also observed the "new star" (really a nova) in Cassiopeia in 1572. He observed a comet in 1577 and was realized that it was not in the atmosphere, but was in space. He corrected most astronomical quantities.
About 27,000 ly distant, it measures 50 ly across. Nova T Scorpii exploded in this cluster in 1860. M80 is detectable in binoculars 2°50' NNW of Antares (a Scorpii - see finder chart below).
