Through a process of nuclear fusion. Basically, atoms or molecules fuse together under extreme pressure and temperature, to create a different element, and release energy at the same time. Usually it is hydrogen molecules fusing to form helium atoms.

What is the temperature of the core of a neutron star?
Depends on the age of the neutron star. As a neutron star no longer has any method to produce heat, it will slowly cool over time. A young neutron star will have a core temperature of about 106 kelvin.
What determines a star's color in the Hertzsprung-Russell diagram?
Surface Temperature, and mass.
What temperature does a star start to fuse hydrogen?
The temperature at which hydrogen fuses is 10,000,000 degrees Kelvin. This is the minimum temperature the core of a proto star has to have to become a true star.
The critical temperature the core must reach for a star to shine by fusion is?
About 10,000,000K.
What determines all the star's properties such as its temperature size brightness or luminosity and life span?
It's Mass
What determines the temperature in the core of a star?
The star's mass determines the temperature in its core. A stars mass will also determined it size and the amount of gravitational pull it will have.
What determines color of the stars?
The temperature determines the color of the star!:)
What determines when a star is born?
A star becomes a star - "is born" - when the process of nuclear fusion begins in the core of the star.
What factor determines the color of a star?
Mainly its temperature.
At what temperature does a star's core reach Carbon detonation?
Temperatures in the star's core can reach 3x109 K.
What is the temperature of the core of a neutron star?
Depends on the age of the neutron star. As a neutron star no longer has any method to produce heat, it will slowly cool over time. A young neutron star will have a core temperature of about 106 kelvin.
Why the temperature of the stars vary from one another?
The temperature in the core of a star depends, to a great extent, on:* The star's mass. The general tendency is that high-mass stars are hotter. * Where the star is in its life cycle. The star's core temperature will vary over time. On the other hand, the star's surface temperature also depends on its size. Thus, it is possible that PRECISELY because a star is hotter in the core, it gets bigger, and the surface temperature DECREASES (though its total energy output increases).
Which part of a star can reach a temperature of a millions of degrees?
The core.
What determines a star's color in the Hertzsprung-Russell diagram?
Surface Temperature, and mass.
What temperature does a star start to fuse hydrogen?
The temperature at which hydrogen fuses is 10,000,000 degrees Kelvin. This is the minimum temperature the core of a proto star has to have to become a true star.
Which star's surface temperature is closest to the temperature at the boundary between earth's mantle and core?
The sun!
The critical temperature the core must reach for a star to shine by fusion is?
About 10,000,000K.
