What may the collapsed core of a supergiant star form?
What the core of the star will become is dependent of the mass of the supergiant star. Stars between about 3 and 10 solar masses will generally become neutron stars. Stars above 10 solar masses generally become black holes.
What is the significance of 3 solar masses in a star's fate?
After a high-mass star explodes as supernova and leaves a core behind, the core would become a neutron star or a black hole. If the core is less than 3 solar masses, it would become a neutron star; if the mass exceeds 3 solar masses, the core would continue to collapse, forming a black hole.
How do super massive rare stars end their life as?
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
Why do you not expect to find a 5 solar mass neutron star?
There are no neutron stars with 5 solar masses because one if a neutron star exceeds 3 solar masses, the neutrons inside would no longer be able to support the extreme gravity, so the neutron star would then collapse into a black hole.A neutron star is prevented from further collapse by a force call neutron degeneracy pressure. Above 3 solar masses gravity will overcome this force and the stellar remnant will collapse completely to form a black hole.
How is degeneracy pressure related to white dwarfs and neutron stars?
White dwarfs are prevented from collapsing further by electron degeneracy pressure. If the mass of a stellar remnant exceeds the Chandrasekhar limit, about 1.4 solar masses, gravity will overcome this pressure and form a much smaller and denser neutron star. Further collapse in a neutron star is prevented by neutron degeneracy pressure up until the Tolman-Oppenheimer-Volkoff limit of about 3 solar masses, at which point gravity causes a complete collapse, forming a black hole.

What type of star is leftover center of an old star?
If you mean after a supernova it could be a neutron star if it's less than 3 solar masses

How far from a black hole's event horizon would you have to be to experience the equivalent of Earth's gravity?
That would depend on the mass of the black hole. Here are some values: 3 solar masses: 3.96 million miles 30 solar masses: 12.5 million miles 1000 solar masses: 72.3 million miles 1 million solar masses: 2.23 billion miles 4 million solar masses: 4.57 billion miles 100 million solar masses: 22.7 billion miles 1 billion solar masses: Within the event horizon
What is the third largest planet in the solar sistem?
The third largest planet in the solar system is Neptune #1 -Jupiter at 318 Earth masses #2 - Saturn at 95 Earth masses #3 - Neptune at 17 Earth masses
What is a stelar black hole?
That refers to a black hole that results from the gravitational collapse of a star, and which has a mass between 3 solar masses and several solar masses, depending on the mass of the star that collapsed.
Is a supernova a super giant?
A supernova may have been a supergiant star at one time, but it did not have to be. Any star with a mass greater than 3 times our sun will supernova. There are millions of stars having masses between 3 solar masses and supergiant mass for every single supergiant star... and every one will supernova when it dies.
What is in the center of the Andromeda galaxy?
The Andromeda's galactic nucleus is a black hole weighing about 3-5 x 10^7 Solar masses, surrounded by a dense cluster of stars. The structure there seems to hint it has a double nucleus.
What is the life cycle of a high-mass star?
For HIGH mass stars- 1. the hydrogen in the core burns until only helium is left. 2. Then the core contracts, while the outer layers expand. 3. It expands into the red-giant stage and 4. then to the super-giant stage. 5. It will finally die in a supernova explosion, 6. leaving behind a white dwarf (if its final mass is less than 1.4 solar masses), a neutron star (if the final mass is between 1.4 and 3 solar masses) or a black hole (if the final mass is more than 3 times that of the Sun).
What is the colour of Polaris?
Polaris or Alpha Ursa Minoris is actually a multi star system of 3 to 5 known stars. Polaris A is a yellowish white giant or supergiant star approx 6 solar masses in mass. Polaris Aa is yellowish white dwarf star in close association with Polaris A (18.5 AU). Polaris B is a yellowish white star about 1.5 solar masses about 2,400 AU from Pol A. All 3 stars are F type stars. A - F7Ib-II, Aa - F7 Dwarf, B - F3V There are 2 other stars thought to be associated with Polaris. Polaris C & D.
