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.

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 property of a star would you use to determine what elements it can create?
The surface temperature of a star is a key property used to determine what elements it can create through nuclear fusion in its core. Different elements require different temperatures to undergo fusion, with heavier elements typically requiring higher temperatures. This temperature determines the rate of nuclear reactions and the types of elements produced in a star.
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?
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.
What determines a star's color in the Hertzsprung-Russell diagram?
A star's color in the Hertzsprung-Russell diagram is determined by its surface temperature. Hotter stars appear blue or white, while cooler stars appear red.
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.
What Inside a star the force of gravity is balanced by the?
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
