What happens to the temperature of the core of a high mass star when fusion ceases?

When fusion ceases in the core of a high mass star, the temperature of the core:



A. Increases

B. Decreases

C. Stays the same

D. Fluctuates wildly



I feel that it is B, but I'm not sureWhat happens to the temperature of the core of a high mass star when fusion ceases?The answers is A.

When fusion ceases the core will collapse and this increases the temperature, more than compensating for the loss of fusion radiation. What exactly happens depends on the age and mass of the star.



If the mass is high enough and the core is not already totally fused into iron, then the next element will ignite. After Helium fusion, Carbon, Oxygen, Neon, Silicium will fuse.



At the end of its life the star will have an iron core and the collapse will trigger a Supernova explosion.What happens to the temperature of the core of a high mass star when fusion ceases?
Well, the fusion causes the heat and if it stops fusing then the heat will decrease.What happens to the temperature of the core of a high mass star when fusion ceases?Well as the star is dying, i would say B.

A star get cooler as it dies.. I think.What happens to the temperature of the core of a high mass star when fusion ceases?
I'd say the answer is A, depending on how massive the star is. If it is over a certain level, the core will collapse under its own gravity and trigger a supernova explosion. The temperatures will then briefly skyrocket to unimaginable levels.What happens to the temperature of the core of a high mass star when fusion ceases?if it inrceases it gets hotter, if itdecreasess the star collapses and dies or expands to a red giant in which case the surface gets hotter and the core cools slightly. stays the same temp is normal.fluctuatess then the temp fluctuates
