Towards the end of its life, a star with a size similar to ours will expand to a red giant star as the core contracts and heats up and the hydrogen fuel supply is consumed. It will eventually lose the outer layers and all that will be left is a core, a white dwarf reminant that will slowly cool over millions of years.

What is the life cycle or a sunlike star?
A sunlike star goes through the following stages in its life cycle: nebula, protostar, main sequence star, red giant, planetary nebula, and finally white dwarf. During the main sequence stage, the star fuses hydrogen into helium in its core, releasing energy. Once it exhausts its hydrogen fuel, it expands into a red giant before shedding its outer layers to form a planetary nebula. The remaining core becomes a white dwarf, cooling down over billions of years.
How long does the main sequence stage of a sunlike normally last?
The main sequence stage of a sunlike star typically lasts for about 10 billion years. It is during this stage that the star fuses hydrogen into helium in its core, maintaining a balance between the force of gravity pulling in and the energy produced by nuclear fusion pushing out.
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 does a sunlike star become in the final state of it's life cycle?
the answer is white dwarf
What will happen to sun when it runs out of fuel if it had 10 times as much mass?
If the sun had 10 times its current mass, it would burn through its fuel faster and evolve into a red supergiant star. When it runs out of fuel, it may go through a supernova explosion, leaving behind a dense core called a neutron star or potentially collapsing into a black hole.

What is in a star's core?
A star's core consists mostly of hydrogen. As the star ages, the amount of helium, carbon and other elements in the core increases as they are the result "ash" resulting from the consumption of the hydrogen fuel.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
When a main sequence star has the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
What triggers a super nova?
When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star
When a main-sequence star has exhausted the fuel in its core it becomes a .?
The next step in its life is to become a "red giant" star.
What is a star with an iron core?
A star with an iron core is typically a red supergiant star that has exhausted its nuclear fuel and is in the final stages of its life cycle. The iron core forms when the star's fusion processes can no longer generate enough energy to counteract gravitational collapse, leading to a supernova explosion.
When a stars core collapses does a giant explosion happen?
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
