An object that collapses under its own gravity to form a star is a star itself. Now a star is formed when hot gases of hydrogen coalesce together due to their gravitational pull. When this hydrogen is all consumed, the star is nothing but a waste. There is no energy to keep it from expanding. During this process the star can go to a supernova state thus forming new stars or a possible black hole.
Answer:
A NEBULA of gas and dust.
The gravitational collapse heats up the material and eventually nuclear fusion can start and a star has formed.

As a galaxy rotates, different gravitational effects can begin the process of gascloud contraction whereby a star (or stars) can form out of it. Another instigator of star formation is the presence of a shockwave from a supernova.
Whatever the cause, the end result is a process of positive feedback. The material in the gas cloud, previously too rarefied to 'do anything' can now start to mass together; and since gravity depends upon mass, this increased gravitational pull thus attracts more material, which increases the gravitational attraction...
Often, especially if the cloud is large, not one, but many stars will form. In that case you will eventually get an open cluster. Over many millions of years, galactic rotation will usually distort the shape of these clusters and all sense of visual clustering will be lost, although we can still identify the members due to their similar spatial motions. Thus, many of the stars of Ursa Major, Leo Minor and Lynx are actually related, since they are at similar distances from us and have similar proper motions.

When is a star formed?
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
Does a supernova implode or explode to form a black hole?
It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.
What is the maximum mass of a star?
The maximum mass of a star is the mass at which it would collapse to form a black hole, irregardless of the stage in its life cycle. It is thought that the centers of the galaxies did this.
How are solar systems made?
The favoured hypotheses today are variants on the Kant Nebular Hypothesis, which have solar systems form from concentrations in the interstellar medium of dust and gas. Such a concentration may collapse inward under its own weight. At the center of collapse, matter may become concentrated enough to undergo nuclear fusion, at which time a star is born. Additional concentrations of matter in the region surrounding a newborn star may fail to reach that density, and eventually become planets.
What two types of stars that can form from nebula?
Any star can form from a nebula. all it needs is some force to make it collapse, like a nearby supernova or gravitational pull.
Is it possible for a black hole to form without the collapse of a star?
A higher-mass star will turn into a supergiant, then a supernova. Then, it will collapse and shed it's outer layer and leave behind a white dwarf. However, the star may collapse even further and become a black hole.
What are the manner in which a society may collapse as a result of corruption?
Financial collapse is the primary form of collapse due to corruption.
When is a star formed?
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
What are some astronomical terms and their meanings?
A black hole is a collapsed star that does not let light escape. A nebula is a mass of gas and dust that may collapse to form a star. A red giant is a star that has expanded and cooled. A white dwarf is an old, dense, cool star.
What causes the collapse of a star?
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.
What conditions of a Supernova cause elements that are heavier that iron to form?
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
What element does a star form once it loses fuel?
The answer will depend on what happens towards the end of its life. A supernova, for example, will form all sorts of elements - including all naturally occurring ones - up to uranium. At the other end a low mass star may collapse into an iron core.

It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.
What makes a high mass star's core collapse?
the high mass star's core collapse because its gravity
What is the maximum mass of a star?
The maximum mass of a star is the mass at which it would collapse to form a black hole, irregardless of the stage in its life cycle. It is thought that the centers of the galaxies did this.
When a black hole collaspes does its mass decrease?
As far as we know, black holes cannot collapse any further. However, if a star were to collapse and form a black hole, its mass would be the same.
Which stars are composed of matter in which electrons have combined with protons?
Stars may collapse to such a degree, perhaps after a supernova, that, in the core, electrons are squashed into the nucleus, reacting with protons to form neutrons. A star of this collapsed state is called neutron stars.
