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.
What else can I help you with?
Where are supernovae?
Supernovae are massive explosions that occur when a star uses up its gas and explodes so they will only occur once a star has died.
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.
Black holes form from the remains of stars that?
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
Why do novae repeat while supernovae do not?
The explosion of novae hardly disturb the white dwarf or its companion star. Mass transfer resumes and a new layer of fuel can accumulate so that the process can happen all over again. In a supernovae, its the death of a star. Its theory that the outer layers of a massive star produces the supernovae while the core collapses to form a neutron star or black hole.
Can a shock wave disrupt an interstellar cloud from creating a star?
On the contrary, shock waves from supernovae can actually trigger star formation.
How long do supernovae last and what factors determine their duration?
Supernovae typically last for a few weeks to a few months. The duration of a supernova is determined by factors such as the mass of the star, its composition, and the energy released during the explosion.
Where is the exploding star in the solar system?
There are no exploding stars (supernovae) in our solar system. Supernovae occur in distant parts of the galaxy, outside our solar system. The nearest known supernova to Earth was Supernova 1987A, which was located in the Large Magellanic Cloud, a satellite galaxy to our Milky Way.
Can Heavier elements like gold and uranium cannot be created in supernovae?
Heavier elements like gold and uranium are primarily formed in explosive events such as supernovae, but they are more significantly produced through a process called neutron capture during neutron star mergers. While supernovae do contribute to the synthesis of certain heavy elements, the extreme conditions and neutron-rich environments found in neutron star collisions are more conducive to creating the heaviest elements. Therefore, while supernovae play a role, they are not the sole site for the creation of all heavy elements.
Where do astrophysical neutrinos come from?
They originate from nuclear reactions, such as those that take place in a star, when cosmic rays hit atoms and in supernovae.
Do all stars that become supernovae leave behind a neutron star?
No. The most massive stars will leave behind a black hole.
What are the key differences between a type 1a supernova and a type 2 supernova?
Type 1a supernovae occur in binary star systems where one star is a white dwarf that accumulates material from its companion until it reaches a critical mass, causing a thermonuclear explosion. Type 2 supernovae happen when a massive star runs out of fuel and collapses under its own gravity, leading to a powerful explosion. The key difference is the mechanism of the explosion: type 1a is caused by thermonuclear reactions, while type 2 is due to gravitational collapse.
What is another word for supernovae?
mainly another name for supernova is star dust cause that's mainly what it is that is how new stars are born just like the sun
