the high mass star's core collapse because its gravity
What else can I help you with?
Why can only very massive stars form a black hole?
When a star dies the core collapses, but in most cases collapse stops at the level of either a white dwarf or a neutron star. The internal pressure of the remnant core is enough to stop further collapse. Only the most massive stars have strong enough gravity to overcome these forces and collapse into black holes.
What makes a high mass star's core collapse?
A high mass star's core collapses when nuclear fusion ceases and gravitational pressure overwhelms the radiation pressure supporting the core. This collapse leads to a rapid increase in temperature and pressure, triggering a supernova explosion.
Why do some stars end up as neutron stars?
Some stars end up as neutron stars because they exploded as a supernova and leaves a dense core behind. The strong gravity of the core compresses itself until protons and electrons are crushed into neutrons, this forms a neutron star. If the core is too massive, it would collapse into a black hole.
What is different about a star from a planet?
Stars are bigger than planets until they finally collapse into dwarf stars. Stars are large enough to produce nuclear energy in their core, so they produce high amounts of heat and light.
Explain why the sun does not collapse under the force of its own gravity?
Stars do not collapse because the inward force of gravity is balanced by the pressure generated by fusion. When stars die they do collapse. The cores of low to medium mass stars collapse to form white dwarfs. Further collapse is prevented y electron degeneracy pressure. More massive stars leave behind neutron stars, in which gravity is balanced by neutron degeneracy pressure. In the most massive stars, once fusion stops producing energy there is nothing to stop the collapse and the core becomes a black hole.
Why do type 2 supernovae occur in massive stars when the core reaches a critical mass of iron?
Type 2 supernovae occur in massive stars when the iron core reaches a critical mass because fusion of iron absorbs energy rather than releasing it. This causes a buildup of inert iron in the core, leading to a collapse due to lack of outward pressure to counteract gravity. The collapse triggers a powerful explosion, resulting in a Type 2 supernova.
Do most massive stars collapse into black holes?
Yes, most massive stars (at least eight times the mass of our Sun) will end their life cycle by collapsing into a black hole. This happens after they have gone through the stages of supernova explosion and core collapse.
What part of the sun is energy produced in?
Nuclear fusion is taking place in the Sun's core that makes the solar energy. Hope this helped! :)
What does increased temperature from contraction in the core cause the helium core to do?
This phenomenon happen during the red phase collapse of smaller stars. The contraction in the core of the star causes the helium to go into a runaway fusion reaction that releases an immense amount of energy for a brief time.

How long does it take a stellar iron core to collapse?
It takes only milliseconds for a stellar iron core to collapse when it reaches the end of its life cycle. This rapid collapse leads to a supernova explosion.
After a supernova the stellar core may remain as a?
After a supernova, the stellar core may remain as a neutron star or, for more massive stars, collapse into a black hole. Neutron stars are extremely dense, composed almost entirely of neutrons, while black holes have such strong gravity that not even light can escape from them.
