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.
What else can I help you with?
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 remains after supernova?
A neutron star or a pulsar, or a black hole.
Why do Interstellar gas cloudss may collapse to form stars if they?
Interstellar gas clouds may collapse to form stars primarily due to gravitational instability. When regions within the cloud become dense enough, their gravitational pull can overcome thermal pressure and other forces opposing collapse. As the material falls inward, it heats up, leading to the formation of a protostar. If the conditions are right, this process can continue until nuclear fusion ignites in the star's core, officially marking its birth.
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.
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.
What has to occur for a star to form?
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.
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.
Why does star formation require a triggering event?
Star formation requires a triggering event because the gas and dust in space need a disturbance, such as a shockwave or gravitational collapse, to overcome their natural tendency to remain diffuse and form into dense clumps that can eventually collapse and form stars.
What are the two things a supergiant star may become when it dies?
When a supergiant star exhausts its nuclear fuel and dies, it may explode in a supernova event. Depending on its mass, the remnants can either collapse into a neutron star or form a black hole. The outcome is determined by the star's initial mass and the processes occurring during the supernova explosion.
What remains after supernova?
A neutron star or a pulsar, or a black hole.
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.
How does the Jeans mass determine the formation of a star when a sound wave travels through a gas cloud?
The Jeans mass is the minimum amount of mass needed for a gas cloud to collapse and form a star. When a sound wave travels through a gas cloud, it can cause the cloud to become unstable and collapse if its mass exceeds the Jeans mass. This collapse leads to the formation of a star.
