What is an explosion seen when a white dwarf captures H from a companion star?
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
Is it true that when a nova destroys the star and leave behind a white dwarf?
Yes, when a star undergoes a nova, it expels material into space, which can eventually form a white dwarf. A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and collapsed under gravity. Novae are different from supernovae, which are more energetic and can leave behind other remnants like neutron stars or black holes.
What causes a nova explosion?
A nova explosion comes about of a white dwarf star has a neighbouring main sequence or aging star and is taking hydrogen and helium gas from that star. Over time, the gasses around the super dense white dwarf star build up and are compressed under the extreme gravity. Eventually the white dwarf star will ignite and explode in a runaway nuclear fusion reaction. Its different from a Super nova explosion.
When does a nova event occurs if a white dwarf accepts material from a nearby?
A nova event occurs when a white dwarf in a binary system accepts material from a nearby companion star, causing a runaway nuclear fusion explosion on the surface of the white dwarf. This explosion results in a sudden increase in brightness that can last for several days to a few weeks.
What causes a nova to explode?
A nova (as distinct from a supernova) is produced in a close binary system where one member is a white dwarf and the other a larger, less dense star. The white dwarf 'sucks' gas from the larger star which condenses into an accretion disc around the white star's equator. When this accretion disc reaches a critical mass it interacts with material on the white star and produces a huge thermonuclear explosion. This is what we see as a nova event. Novae are variable stars.
Forms when a white dwarf flares up?
nova
What stage occurs before a nova explodes?
white dwarf
What stage occurs after the red giant?
white dwarf/nova
When a nova destroys a star does it leave behind a white dwarf?
A nova is a cataclysmic nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star. Nova are not to be confused with Type Ia supernovae which do explode [See Link]
What is an explosion seen when a white dwarf captures H from a companion star?
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
What two stars can form a nova?
A Main Sequence star and a White Dwarf.
Is it true that when a nova destroys the star and leave behind a white dwarf?
Yes, when a star undergoes a nova, it expels material into space, which can eventually form a white dwarf. A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and collapsed under gravity. Novae are different from supernovae, which are more energetic and can leave behind other remnants like neutron stars or black holes.
What is the life cycle of a yellow star?
Nebula protostar mid sized star red giant nova white dwarf black dwarf:)
What can a white dwarf do to it's companion star?
Depending on the distance between the binary pair, it is possible for the white dwarf to draw gas from it's companion causing the star to reach the Chandrasekhar limit causing the white dwarf to explode as a nova or a type La supernova.

What is the brightest star white dwarf nova red giant or main sequence?
Red giant is the largest and the brightest.
