Well, my friend, during the collapse of a star, some of the material gets pushed inward to the center of the star. This is where all the magic happens, and eventually, that material can come together and create something new and beautiful in the universe. Just like when we make happy little trees in our paintings, the cycle of creation and change in the cosmos is happening all around us.
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
The main source of energy during this stage is gravitational potential energy, as gas in the interstellar cloud collapses under gravity to form a protostar. The energy released from this gravitational collapse heats up the material and initiates the process of star formation.
A nebula can collapse into a dense mass when its gravitational attraction overcomes the outward pressure of gas and dust within it. This collapse can be triggered by external forces, such as a nearby supernova explosion or a shock wave from a passing star, causing the nebula to start contracting due to gravity. As the material compacts, its density increases, eventually leading to the formation of a protostar or a star.
Some complications that interfere with star formation include external pressure from nearby stars or galaxies, the presence of magnetic fields that can inhibit the collapse of gas clouds, and the effects of radiation from massive stars that can heat and disperse gas clouds before they can collapse to form a star.
a strong gravitational force which means that the star will collapse in on itself
After a star with four solar masses dies, it can collapse and form either a neutron star or a black hole, depending on how much material is left behind after the explosion during its death throes.
Supernovae are caused by the gravitational collapse of massive stars. When the material in the core of the star reaches the density of an atomic nucleus, nuclear forces (actually "neutron degeneracy pressure," but that's a whole new topic) balance gravity and the collapse is suddenly halted. This creates a shock front between the material that has stopped and the material that is still falling inward. The shock front moves moves outwards (only direction it can go, think about it) through the star and explodes as a supernova. So, to answer your actual question, that small dense remnant is called a neutron star. If the neutron star can steal some material from somewhere (either another star or perhaps the remains of its parent star), it might become so big that gravity becomes dominant again, and will collapse, this time into a black hole.
The collapse of a star is based on its age. When it runs out of "Fuel" its inside contracts as the outside expands. it can then super nova or collapse into a tiny star.
For a star to form, a cloud of gas and dust in space must collapse under its own gravity, causing the material to heat up and ignite nuclear fusion, creating a star.
A black hole or a neutron star, depending on the mass of the remaining core. Also a lot of material is ejected into space.

Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
A star is often referred to as a "protostar" during its early formation stage. This occurs when gas and dust in a molecular cloud collapse under gravity, leading to the accumulation of material that heats up and begins to form a new star. As the protostar continues to gather mass and temperature rises, it eventually reaches the point of nuclear fusion, at which point it becomes a main-sequence star.
One of the events that did not occur during the collapse of the solar nebula was the formation of the first stars in the universe. Instead, the collapse of the solar nebula led to the formation of our solar system.
The main source of energy during this stage is gravitational potential energy, as gas in the interstellar cloud collapses under gravity to form a protostar. The energy released from this gravitational collapse heats up the material and initiates the process of star formation.
After a high mass star explodes, the leftover material forms a remnant called a neutron star or a black hole. If the core of the star is less than about 3 times the mass of the Sun, it collapses to form a neutron star. If the core is more massive, it collapses further, causing the gravitational collapse to form a black hole.
