Just as a low-mass main sequence star runs out of fuel in its core it actually becomes brighter How is this possible?
The core contracts, raising the temperature and increasing the size of the region of hydrogen shell-burning.
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 is the parts of the star?
It depends on how massive the star is and what part of its life its at. Most of the time the core is the hottest, but after a star runs out of its current fuel it will start fusing elements in a shell around its core out to the surface or photosphere. While these shells are burning they are the temporary hotspots of the star, while the core gets hotter and hotter.
When does a star form a nebula?
A star forms a nebula when it runs out of fuel. The star either becomes a red giant or a supergiant, then the star would be blown off into space either by expansion or explosion. The outer layers, which was released into space, would become a nebula, or sometimes a part of a larger nebula.

What is formed when a red supergiant runs out of fuel at its core?
black hole
Which progression do astronomers expect our sun to follow as it runs out of fuel?
When the sun runs out of fuel it is expected to turn into a red supergiant engulfing earth. Then it is supposed to shrink into a white dwarf.
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 red supergiant runs out of fuel at its core?
A stars usual and preferred fuel is hydrogen. For most of it's life it will be fusing hydrogen and releasing energy in the process and making larger nuclei. Once it has used up the hydrogen, it will then burn more of the heavier elements such as the helium that it had produced during it's main sequence. Depending on the stars mass, it will go through various phases of fusing heavier nuclei, with burn phases becoming progressively shorter. The dynamics involved mean that the star may expand to a red giant or red supergiant during these phases, if it's mass is sufficient.
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
Just as a low-mass main sequence star runs out of fuel in its core it actually becomes brighter How is this possible?
The core contracts, raising the temperature and increasing the size of the region of hydrogen shell-burning.
How is neutron degenerate matter created?
Neutron stars are created when a massive star runs out of hydrogen to burn and become a supergiant. The supergiant will then explode and only leaves a core and a nebula. The dense core will then become a neutron star or a black hole.
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.
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.
Where do neutron stars form?
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
