What will happen to the core of the sun when the hydrogen supply runs out?
It will shrink and its temperature will increase
What is the next phase of the sun after the core has mostly helium with a thin layer of hydrogen outside?
Red Giant star
What happens to the sun's temperature when the core shrinks due to the falling reaction rate?
It increases
What temperature is needed for helium to 'burn' and produce carbon?
$600$ million K
What happens to low mass stars when they cannot reach the temperature needed for carbon fusion?
They expand to become supergiants
What is the eventual fate of the earth as the sun becomes a Red Giant star?
It will be engulfed by the expanded sun
What does the reaction rate falling cause in the core of low mass stars?
Shrinkage and heating up of the core
What happens when helium is depleted in the sun's core and its reaction rate falls?
Shrinkage and heating up of the core
Learn about the eventual fate of the sun as its hydrogen supply runs out, leading to the production of helium and a shift in its core composition. Understand the timeline and processes involved in this natural astronomical phenomenon.
