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 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?
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.
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.
