Which of these objects has the largest radius a 1.2M rm Sunwhite dwarf a 1.5M rm Sun neutron star a 3.0M rm Sun black hole?
1.2M sun white dwarf
What remains after supernova?
A neutron star or a pulsar, or a black hole.
What is the radius of a black hole singularity?
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
Can any black hole turn into a neutron star?
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
What is the Schwarzschild radius?
The Schwarzschild radius is the radius of the event horizon surrounding a non-rotating black hole. Any object with a physical radius smaller than its Schwarzschild radius will be a black hole.
Stage in which the star comes to its smallest shape?
Neutron star -- then black hole
Which of these objects has the largest radius a 1.2M rm Sunwhite dwarf a 1.5M rm Sun neutron star a 3.0M rm Sun black hole?
1.2M sun white dwarf
What remains after supernova?
A neutron star or a pulsar, or a black hole.
How is the neutron star different from a black hole?
A neutron star is the remnant of a massive star. It consists of an extremely dense collection of neutrons that is prevented from collapsing further by neutron degeneracy pressure. While they have extremely strong gravity, neutron stars still emit light. A black hole is an object that has completely collapsed under the force of gravity, forming an infinitely dense singularity. Within certain radius, nothing, not even light escapes.
What is the radius of a black hole singularity?
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
The smallest stars are called stars.?
Degenerate stars
Can any black hole turn into a neutron star?
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
How are black hole different from neutron star?
A neutron star is an extremely dense object in which atoms have been crushed by gravity, causing electrons and protons to merge into neutrons. A force known as neutron degeneracy pressure prevents it from collapsing further. The neutron star can emit light and other forms of radiation. A black hole is an object that has completely collapsed under the force of gravity, with all mass coming to a single point called a singularity. The gravity is so strong that, within a certain radius nothing, not even light, can escape.
What is the color of oldest star?
The oldest stars are now mostly either white dwarfs or neutron stars. A few of the largest may be black holes.
How are black holes and neutron stars defined?
Neutron star is the final pile of stellar ash left when a supernova explodes, provided that star from whence the supernova came did not exceed a certain radius. The neutron star "ash heap" is intensely hot, weighs millions of tons per square inchand usually spins very, very fast. If the star that became a supernova exceeded a certain radius, it's collapsed core will be so heavy, it generates a gravitional pull so strong that not even light can escape from it, hence it cannot be seen. It is called a "black hole".
What is the Schwarzschild radius?
The Schwarzschild radius is the radius of the event horizon surrounding a non-rotating black hole. Any object with a physical radius smaller than its Schwarzschild radius will be a black hole.
How large can the volume of a black hole get?
There is no theoretical limit to the MASS of a black hole. The largest known black holes have a mass in excess of a billion solar masses... so far. In the distant future, you can expect them to continue growing.The DIAMETER or the RADIUS of a black hole is directly proportional to the black hole's mass; the radius would be about 3.0 kilometers for every solar mass. The diameter, of course, is twice as much. Thus, a black hole of 10 billion solar masses would have a radius of 30 billion kilometers... about 200 AU.
