What happens when the gravity of a massive star overcomes neutron degeneracy pressure?
When the gravity of a massive star overcomes neutron degeneracy pressure, the core collapses under its own gravity, leading to the formation of a black hole or a neutron star, depending on the initial mass of the star. This process releases a tremendous amount of energy in the form of a supernova explosion.
Is it true that fusion provides a force that balances the inward force of gravity in creating stars?
Sort of - there energy released by the fusion occurring in the core of the star balances the force of gravity trying to make the star collapse inwards.As a star evolves this balance changes and the size of the star will change over time. When the material available for fusion runs out in the core, gravity wins the fight.
Why doesn't a star expand or collapse during the main sequence?
A star maintains equilibrium during the main sequence because the inward force of gravity is balanced by the outward pressure from nuclear fusion in its core. This balance between gravity and radiation pressure prevents the star from collapsing or expanding significantly during this phase.
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.
What would happen if the sun had no core?
The core is necessary for a star's existence, it's the engine that keeps it from collapsing. When this engine runs out of fuel or its fuel vanishes, gravity overcomes and contracts the star until matter from the radiative zone is compressed enough to start fusing hydrogen again to counterbalance gravity.
What cause a neutron star to form?
The strong gravity of the core of a dead high-mass star causes a neutron star to form. When the high-mass star becomes a supernova and leaves a core behind, the core no longer undergo fusion. Without fusion, gravity starts to push the core inward until most protons and electrons are crushed into neutrons, a neutron star forms. If the core is too massive, the neutron star would collapse and become a black hole.
What makes a high-mass stars core collapse?
the high mass star's core collapse because its gravity
How does Gravity play a role in the Death of a Star?
Gravity plays a crucial role in the death of a star by causing the core to collapse after nuclear fusion ceases. This collapse can lead to either a supernova explosion or the formation of a black hole, depending on the mass of the star. Gravity compresses the star's core, triggering intense reactions and releasing enormous amounts of energy, ultimately leading to the star's demise.
What does the core so for the sun?
The core of the Sun is the only part of the Sun (and all stars) that is compressed by gravity enough to maintain runaway thermonuclear reactions to counterbalance the star's own gravity.

What Inside a star the force of gravity is balanced by the?
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
Why does the core collapse once fusion stops?
The energy released by fusion in the core of a star produces an outward pressured force that counteracts gravity. When fusion stops, that force goes away and gravity takes hold, causing the core to collapse.
What prevent the enormous amount of energy released from the fusion reactions at star's core from blowing the star apart?
Gravity. However, sometimes the star IS blown apart.
When a star has exhausted its supply of hydrogen?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
What force acts between a planet and a star to cause variation in the motion of the star?
The effect on the star is usually quite small, but the force is "gravity".
How does gravity and nuclear fusion affect a stars size?
Gravity will cause a star to become smaller, because it pulls matter towards the star's core and causes it to contract. On the other hand, nuclear fusion will cause a star to become larger, because it produces an outward pressure, pushing the star's matter outwards and causing it to expand.
