How is energy generated in the core of a star?
it was born with a name PRECIOUS
How do stars make radiant energy?
Thermonuclear fusion in the core of the star heats the material of the star. A series of complex energy transfer mechanisms transport the heat from the core to the photosphere of the star. The photosphere then emits electromagnetic radiation.
Suns core releases heat by what process?
Our sun release energy by a process called convection. Inside the star, energy is transported towards the surface through radiation, but about 1/3 of the outer layer of the star is markedly cooler than the core and the energy is transported by convection from the core to this layer.
The energy source of stars is primarily associated with?
hydrogen fusion in the core. eventually runs out of hydrogen in the core and hydrogen fusion moves to the shell whilst the core contracts (star expands into red giant)...star leaves the main sequence.
A star located off the main sequence indicates what?
That the star has stopped fusing hydrogen in its core as its energy source.
Why do stars cool when the fusion cycle gets to iron?
Unlike lighter elements, fusing iron consumes more energy than it produces. This does not, however, cause a star to cool. Once a star gets to the point of fusing iron, the core stops producing energy and without the pressure from the heat it produces, the core collapses while the rest of the star is blasted away in an explosion.
Why can't a lower-mass star generate energy through carbon flash?
A low-mass star never gets hot enough in the core to fuse helium into carbon.
Where the sun gets its energy?
nuclear reactions at its core
How is energy generated in the core of a star?

How does influenza get energy from food?
It gets its energy from phospholipids and polypeptides in the inner core of our tissues

What produces light in a star?
energy released during the process of nuclear fusion in the star's core
How is energy created in a stars core?
As with our Sun (a star) by nuclear fusion.
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).
Suns core releases heat by what process?
Our sun release energy by a process called convection. Inside the star, energy is transported towards the surface through radiation, but about 1/3 of the outer layer of the star is markedly cooler than the core and the energy is transported by convection from the core to this layer.
What occurs in a core of a star as the protons collide?
The atoms in the core of a star fuse together under the intense pressure, producing vast amounts of heat and energy.
How are black holes made and how big can they get?
Black holes are made just before a star dies. The stars core radiates outward pressure to balance out the gravity pushing down on it. When the cores energy runs out gravity gets the upper hand and compresses the star. As the star gets compressed the core heats up and implodes and swallows itself. The bigger the star the more gravity there is acting upon it meaning a bigger black hole. If the star is made of tougher stuff it becomes a white dwarf or a neutron star. Hope this helps!
