As heavier elements are formed by fusion a massive star expands into?
Stellar evolution
How does a star change when it begins combining heavier elements?
Elements withing a burning star combine until the core becomes iron, which is too dense to combine into anything else. Depending on the size of the star, how many solar masses it is, it will either cool off or, if it's big enough then it turns into a black hole, due to the massive gravitational pull it has within its core.
As heavier elements are formed by fusion a massive star expands into a what?
A super giant
What causes a planet to become a star?
A planet cannot become a star. A star is an object that is massive enough to release energy via nuclear fusion. A planet is much less massive.
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
In Binary Stars the initially less massive Star can die first?
Yes they can
When heavier elements form by fussion a massive star expands into a what?
ether a pulsar or a black hole depending on the mass of the star
What factor determines how a star lives?
I assume you mean, "how long a star lives". That depends mainly on the star's mass, with more massive stars using up their fuel way faster than less massive ones.
Is the sun a massive star or a dwarf star?
its not a massive or a dwarf star
What is a massive collapsed star?
A massive collapsed star is a dead star.
How does a stars mass affect its life cycle?
The more massive a star is, the less its life time.
Can iron undergo fusion in any star?
No. Only the most massive stars can fuse iron.
