What happens to a star's nuclear energy generation change if the core decreases in temperature?
The prime force at work in all stars is gravity. And gravity is directly related to the amount of mass present. When stars start their nuclear reactions, they do not...

In a main sequence star the gravity of the core is balanced by the outward pressure of the heat created by fusion of hydrogen atoms, maing it stable. So when the hydrogen is used up, does the star expand to form a red giant because the outward pressure?
When a star's core fuses all of its hydrogen into helium, the core contracts. The temperature and intense pressure caused by the contractions causes helium to begin fusion in the...

So when the hydrogen is used up, does the star expeand to form a red giant because the outward pressure?
When a star less than 8 solar masses runs out of Hydrogen in its core, the balance between outward pressure and gravity is lost. The core then starts to collapse....

How long does it take for energy produced in the core of the Sun to reach the earth?
But the Gama rays produced in the core travels through the gases of Sun and takes million years to reach its surface as they collided with atoms...During the travel it...

How do the fusion reactions in the sun compare to the fusion occurring in larger stars and supernovas?
In a smaller star such as the main process of fusion from Hydrogen to Helium is the proton-proton chain reaction. This is where two protons combine under the strong nuclear...

What are the similarities and differences between the earth's core and the sun's core?
Both of these are similar as they are hot. However as is obvious, one is a planetary core and the other a stellar core, 's core is made up of...

How does the Earth's core affect Earth's atmosphere?
The degree of tilt and the frequency of a "wobble" in the earth's orientation towards have a significant effect on the amount of solar radiation reaching the planet. Solar radiation...

How does the earth's core differ from other planets in the solar system?
These metals are found under 's crust in a liquid form and are also found on the core in the form of solid. Its almost very dense as compared...

Why do P-waves travel faster through the inner core than the outer core?
The enormous pressure in the inner core means bonds between the (mainly) iron and nickel atoms are ‘squashed’. This raises their energy and consequently their stiffness. The speed of any...

What separates the inner core from the outer core?
Enveloped by mantle-core boundary, the outer core might not be spherical. Propagation of seismic waves, partly with reflection, marks the separation between mantle and outer core. Only primary waves enter....
