What if a supernova was caused by the black hole at the center of the galaxy?
Black holes do not create supernovae. Black holes are created from a supernovae.
Is a supernova massive?
A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.
What are the byproducts of Supernovae?
All the elements of the periodic table apart from hydrogen and helium are synthesised in the explosion of a supernova.
When does supernova occur?
If two stars begin to orbit. However, novae are more common that supernovae, so you can't really say if the result of a binary will be a nova or a supernova.
What role did supernova play in creating the natural elements?
It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.
How did supernova SN 1987A differ from most other observed supernovae?
It was visible with the naked eye.It did not originate within the Milky Way.
What is the supernova of a red dwarf?
According to prevailing astronomical theory, red dwarfs do not become supernovae, so the best answer to the question is "nonexistant."
Has there been a recorded supernova in the Milky Way?
There have been several recorded supernovae in the Milky Way. The earliest recorded Milky Way supernova was SN 185 (seen, as the name implies, in 185 C.E.), and the most recent supernova recorded was SN 1604 (seen in 1604 C.E.), or Kepler's Supernova.
What is the difference between Type I and Type II supernovae?
supernovae are classified by the lines in their spectra (which indicate which elements are present). type I supernovae have no hydrogen lines, having been caused by the explosion of a star with no hydrogen envelope. type II supernovae have hydrogen lines, indicating that the exploding progenitor star had retained a significant amount of its hydrogen before its supernova. type I supernovae are further classified based on the presence of silicon lines, which are present in type Ia supernovae but not types Ib and Ic.
What is supernovae star?
A supernova is, basically, a large star (more than 2-3 times the mass of the Sun) exploding. Considering a Nova, the abovenumbers are in question.
Fusion reactions in red super giants and supernovae create what?
Different things. A red giant fuses helium, whereas a supernova catastrophically explodes. There is no similarity.
How is it the super novas after the big bang didn't form black holes but rather elements?
There are two explanations. First, when a massive star forms a black hole, usually only a small portion of the star's mass actually goes into the black hole. Most of the rest is blasted away in a supernova, enriching the surrounding space with heavier elements. Second, there are also pair-instability supernovae. Such supernovae occur in extremely massive stars with a very low content of heavier elements, which likely existed in the early universe. Pair-instability supernovae will blow away the entire star, leaving behind no black hole or neutron star remnant.
