What is a nova?

Question

Not a supernova a nova

Thanks a bunch!

Answer 1

A nova is the resulting explosion of a white-dwarf rapidly fusing leftover hydrogen from the stars main sequence after gravity has pulled it back in. A white-dwarf can also pull some of its binary stars hydrogen away from it to also cause a nova to occur. I hope this helps.

Answer 2

A nova is a huge and sudden burst of energy of a "dying" sun. It can happen in intervals and in many single bursts ,,, but it can (in theory) also happen all in one burst. It never ever is an explosion as like as many people think. A "quick" nova still takes about at least 2 years, before the reminders finally collapse, either to a brown or red dwarf, or to a neutron star, or , if giant enough (see Supernova) even to a black hole)
Supernova and nova are practically the same thing, however, the supernova happens on a much greater scale (more energy, more forces and more mass is involved)

Answer 3

A nova (pl. novae) is a cataclysmic nuclear explosion caused by the accretion (of hydrogen onto the surface of a white dwarf** star

.*accretion: The growth of a massive object by gravitationally attracting more matter, typically gaseous matter in an accretion disc. Accretion discs are common around smaller stars or stellar remnants in a close binary, or black holes in the centers of spiral galaxies. Some dynamics in the disc are necessary to allow orbiting gas to lose angular momentum and fall onto the central massive object.

Answer 4

A nova is a star that suddenly increases its brightness by a factor of hundreds of thousands by ejecting some of its matter into space. A super nova is just a much greater event.

Answer 5

Hi. Some stars explode with less force than a supernova, and some do this over and over. Is that what you mean? http://www.answers.com/nova?cat=technology&gwp=13
