A nova is created when additional material is accreted onto the hot surface of a white dwarf.
If sufficient material is accreted that pushes the mass of the white dwarf over the Chandrasekhar limit of about 1.38 solar masses a type Ia supernova will occur.

What else can I help you with?
Do medium size stars become black holes?
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
What are the 3 corpses of stars?
The three corpses of stars are white dwarfs, neutron stars, and black holes. White dwarfs are remnants of low to medium-mass stars that have shed their outer layers, leaving behind a hot core. Neutron stars form from the collapse of massive stars in supernova explosions and are incredibly dense, composed mostly of neutrons. Black holes result from the gravitational collapse of very massive stars, creating regions in space with gravity so strong that not even light can escape.
What was the Seven Dwarfs house called?
The Dwarfs house is called the Dwarfs small cottage. In Disney's Snow White. There was no name in that cottage. But one author made a name of it 2 years after Disney made the cartoon version. The author named it Dwarfs small cottage because the Dwarfs were in a small cottage in the forest.
Which stars do not have nuclear fusion occurring in their core?
All stars "burn" by the process of nuclear fusion. When fusion has been completed, the star dies. That can occur in several different ways and the interested party could look into the topic of stellar evolution. Neutron stars, black holes and white dwarfs are examples of end stages of stellar evolution. Some stars never really reach the stage of fusion and such large objects are called brown dwarfs. If Jupiter were not a planet, it might be deemed a brown dwarf.
Why are white dwarfs important?
Well, they don't affect us directly... But it's interesting to know that most stars - and pressumably that will include our Sun - will end up as a white dwarf, eventually. The exception is the most massive stars, which become neutron stars or black holes.
What is the diffrance between stars that become white dwarfs and stars that become neutron stars?
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
What has the author Dongsu Kyu written?
Dongsu Kyu has written: 'Neutron stars and white dwarfs in galactic halos?' -- subject(s): White dwarfs, Neutron stars
In what ways are neutron stars and white dwarfs similar?
Neutron stars and white dwarfs are both remnants of dead stars, but neutron stars are much denser and have stronger gravitational forces compared to white dwarfs. Both objects are composed mostly of degenerate matter, but neutron stars are made up of neutrons while white dwarfs are made up of electrons.
What stars have the highest densities?
Black holes, neutron stars, and the white dwarfs
What is the difference between star that become white dwarfs and stars that become neutron stars?
the simple reson is mass.......that is if the star under consideration is a heavy one, it is more likely to turn into a black hole and if it is comparatively smaller it is prone to turn into a neutron star or a white dwarf
What is a Very small hot star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
Neutron stars smaller then white dwarfs are thought to be remnants of?
Neutron stars smaller than white dwarfs are thought to be remnants of massive stars that have undergone supernova explosions. When these stars exhaust their nuclear fuel, they collapse under their own gravity, resulting in a neutron star if the core's mass is sufficient. In contrast, white dwarfs are formed from less massive stars that shed their outer layers, leaving behind a dense core. Therefore, neutron stars represent the end stage of more massive stellar evolution compared to white dwarfs.
What is a small hot very dense star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
What are the smallest stars?
The smallest stars known are red dwarfs, which typically have masses less than half that of our Sun. These stars are the most common in the universe and can be as small as about 8% of the mass of the Sun. Despite their small size, red dwarfs can have long lifespans, burning steadily for billions of years.
How is degeneracy pressure related to white dwarfs and neutron stars?
White dwarfs are prevented from collapsing further by electron degeneracy pressure. If the mass of a stellar remnant exceeds the Chandrasekhar limit, about 1.4 solar masses, gravity will overcome this pressure and form a much smaller and denser neutron star. Further collapse in a neutron star is prevented by neutron degeneracy pressure up until the Tolman-Oppenheimer-Volkoff limit of about 3 solar masses, at which point gravity causes a complete collapse, forming a black hole.
Is this true or false brown dwarfs white dwarfs and neutron stars are all kept from collapsing by degeneracy pressure?
True. Brown dwarfs, white dwarfs, and neutron stars are all supported against collapse by degeneracy pressure, which is a quantum mechanical effect that arises when particles are packed densely together and cannot occupy the same quantum state. This pressure prevents further gravitational collapse and supports the star against its own gravity.
