What does a dead star look like?
A dull star
When a collapsed core becomes so dense only neutrons can exist there a what is formed?
A Neutron Star
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
What is a dead star with the density of an atomic nuclei called?
neutron star
What is the name of a star that is about to die?
A star is considered "dead" when nuclear fusion stops in its core. The name of the a star before this happens depends on its size. If its a star the size of our own, Sol, then it will be called a red giant. If it is considerably lager then it will be called either a giant, bright giant, super giant or hyper giant. This again depends on its size.
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 is is a cold dead star called?
white drawf
What does helium have to do with a star?
Helium is formed in the core of the star (like the sun) by the nuclear fusion of hydrogen isotopes.
What is the central portion of a star called that produces energy through nuclear reactions?
core
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.
In the Solar System if the Sun is a Star what is the Moon?
its a fragment of a dead star. or a dead satr like the earth is I couldn't understand you're answer can you be more clear like what is a satr?
What is old dead small star?
Technically a dead star is when a star no longer undergoes nuclear fusion. Depending on the mass of the original star this will either be a white dwarf, neutron star or black hole. These are called stellar remnants.
