As heavier elements are formed by fusion a massive star expands into?
Stellar evolution
Why is the fusion of iron a problem for a star?
Unlike all lighter elements, fusing iron consumes more energy than it produces. Once a star's core starts iron fusion it stops producing energy and collapses. The collapse then blows away the outer layers of the star in a massive explosion called a supernova.
What is a massive collapsed star?
A massive collapsed star is a dead star.
Process is how the sun produces energy?
Nuclear fusion. Atoms are smashed together in the star's core, releasing massive amounts of energy.
Can iron undergo fusion in any star?
No. Only the most massive stars can fuse iron.
The last two elements that a massive star produces are hydrogen and helium why is this the last reaction?
The star can fuse up to iron, because iron is the most stable element.
As heavier elements are formed by fusion a massive star expands into?
Stellar evolution
What is the combining of less massive elements on a star?
Nuclear fusion.
As heavier elements are formed by fusion a massive star expands into a what?
A super giant
How long does the main phase last in a massive star?
The more massive the shorter - down to just millions of years.
What is the life span of a star?
It varies considerably. A star similar to our sun will last about 10 billion years. The least massive stars may last trillions of years wile the most massive may last only a few million.
What happens when heavier elements are formed by fusion then a massive star expands?
yes as heavy elements are used for fuel the star expands this is what will happen to the earth it will swell to a red giant engulfing the inner 3 planets as it slowly dies
What causes the sun to burn?
hydrogen is at the heart of a star, meaning that as it reacts it produces a massive amount of heat and light

Is the sun a massive star or a dwarf star?
its not a massive or a dwarf star
