what is the relationship between a supernova?
533051
A supernova happens where there is a change in the core, or center, of a star. ... One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.

In astronomy, a period-luminosity relation is a relationship linking the luminosity of pulsating variable stars with their pulsation period. The best-known relation is the direct proportionality law holding for Classical Cepheid variables, sometimes called Leavitt's law.

A nova is an explosion from the surface of a white-dwarf star in a binary star system. A nova occurs when the white dwarf, which is the dense core of a once-normal star, “steals” gas from its nearby companion star. When enough gas builts up on the surface of the white dwarf it triggers an explosion.

Nebular hypothesis do not cover formation of the stars or anything preceding the star. For Big bang theory on the other hand it is the planets that have lower priority.

Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.

There actually are simple... The only way our sun could go supernova is if another massive body, say, a Red giant or even a smaller white dwarf fell into a low orbit. ...

Binary star systems are very important in astrophysics because calculations of their orbits allow the masses of their component stars to be directly determined, which in turn allows other stellar parameters, such as radius and density, to be indirectly estimated.

Type Ia supernovae (SNIa) are thought to be the result of the explosion of a carbon-oxygen white dwarf in a binary system as it goes over the Chandrasehkar limit, either due to accretion from a donor or mergers.

Neutron stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.

A type of exploding star – Ia supernova – is known in cosmology circles as a "standard candle" for its consistent bright flash, letting astronomers calculate how far it lies from Earth. ... The ensuing nuclear fusion blasts the star apart in an explosion five million times the brightness of the Sun – the standard candle.

What is the relationship between the heavy elements that we find on earth today and supernovae? All elements in the universe besides hydrogen and small amounts if helium were created during supernovas billions of years ago, 99% of all matter in earth was created during supernovae.

A type I supernova occurs in closed binary systems where two average stars orbit around each other quite closely. ... A type II supernova occurs in larger stars of around 10 solar masses. After it leaves the main sequence it starts fusing increasingly heavy elements in shells around the core.

Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence. However, their life cycles start to differ after the red giant phase. A massive star will undergo a supernova explosion.

The main difference between stars and planets is that stars have high temperatures compared to planets. ... Because they radiate energy, stars are very bright objects. Planets do not generate their own energy through nuclear reactions. They reflect some of the radiation coming from their parent star.

A nova is an explosion from the surface of a white-dwarf star in a binary star system. ... A supernova is a violent stellar explosion that can shine as brightly as an entire galaxy of billions of normal stars.

Supernova remnant, nebula left behind after a supernova, a spectacular explosion in which a star ejects most of its mass in a violently expanding cloud of debris. At the brightest phase of the explosion, the expanding cloud radiates as much energy in a single day as the Sun has done in the past three million years.

The stars mass (once it becomes a star) is inversely proportional to its lifetime as a main sequence star. A red dwarf can survive for many billions of years; a star that has twice the mass of the Sun, such as Sirius A, will have 25% of the Suns lifetime.
