What two stars can form a nova?
A Main Sequence star and a White Dwarf.
What type of stars are there in space?
; Binary Stars, Black Dwarf,Black Hole,Brown Dwarf,Galaxy,Main-Sequence Stars,Nebula,Neutron Star,Nova,Pulsar,Quasar,Red Giant,Supergiant,Supernova,Variable Star,White Dwarf,Wolf-Rayet Star...................
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.
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
Name an exploding star which is a 4 letter star name and starts with letter n?
Nova. "Exploding stars" were originally called "new stars", which in Latin is "nova stellarum".
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 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.
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.
The point in stellar evolution when a star has used up all its fuel and is radiating away its remaining thermal energy as light?
White dwarf stage. Note that not all stars reach this stage. Some stars experience runaway criticality and go supernova. Also, white dwarf stars in binary systems can still go nova if they are acquiring hydrogen from their partner.
What is the explosion of a dwarf star called?
The explosion of a dwarf star is called a nova or a supernova, depending on the type of dwarf star and the circumstances of the explosion. Novas are less powerful explosions caused by a white dwarf siphoning material from a companion star, while supernovas are much more energetic explosions that can occur in white dwarfs or other types of stars.
