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.
The temperature in the core of a star is determined by the balance between the force of gravity compressing the gas and the nuclear fusion reactions happening inside the core. The energy released from these fusion reactions generates heat and maintains a high core temperature.
The mass of the star.More massive the star more is the gravity and the particles at the core are compressed and heated up.
For stellar remnants - a neutron star.
For main sequence stars - a type O or blue star.
The coolest active stars are the red dwarfs, with surface temperatures that are lower than 4000 Kelvin.

What is the temperature of the core of a neutron star?
The temperature of the core of a neutron star can range from around 1 million to several billion degrees Kelvin, making it incredibly hot. This high temperature is a result of the extreme density and strong gravitational forces present in the core.
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.
What factor determines if a neutron star forms or a black hole forms after a supernova explosion?
The factor that determines whether a neutron star or a black hole forms after a supernova explosion is the mass of the collapsing core of the star. If the core's mass is between about 1.4 and 3 times the mass of the sun, a neutron star is formed. If the core's mass exceeds about 3 solar masses, a black hole is likely to form.
What causes the star temperature to increase?
The temperature of a star increases when nuclear fusion reactions in its core release energy. As more hydrogen is converted into helium through fusion, the core becomes hotter due to the increased energy released. This increase in temperature leads to the star shining brighter and hotter.
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 core of a star?
The temperature of the core of a star can reach millions of degrees Kelvin due to nuclear fusion reactions that generate immense heat and light. This intense heat and pressure in the core are what sustain a star's energy output.
What is the temperature of the core of a neutron star?
The temperature of the core of a neutron star can range from around 1 million to several billion degrees Kelvin, making it incredibly hot. This high temperature is a result of the extreme density and strong gravitational forces present in the core.
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.
If the core temp of a star decreases what happens to the radius?
If the core temperature of a star decreases, it will contract, causing the core to become denser. This contraction may lead to an increase in temperature in the outer layers, causing the star to expand its radius to re-establish equilibrium.
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 star with a surface temperature closest to the boundary between Earth's mantle and core would be the Sun, with a surface temperature of about 5,500 degrees Celsius. The temperature at the boundary between Earth's mantle and core is estimated to be around 3,000-4,000 degrees Celsius.
