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?

As heavier elements are formed by fusion in the core, a massive star will eventually exhaust its nuclear fuel and trigger a supernova explosion. This explosion will generate immense energy, leading to the production and dispersal of even more heavy elements into space.


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.


When heavier elements form by fussion a massive star expands into a what?

When heavier elements form by fusion, a massive star expands into a red supergiant. This is a stage of stellar evolution where the star increases in size and becomes much more luminous.


In Binary Stars the initially less massive Star can die first?

Yes they can


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 elements are in Eta Carinae?

Eta Carinae is a massive binary star system located in the Carina constellation. It consists of two massive stars, with the primary star being a blue hypergiant and the companion likely a massive hot star. These stars are surrounded by a dense nebula of gas and dust.


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 are elements more massive than iron (Fe) created in the universe?

Elements more massive than iron are created through processes such as supernova explosions and neutron star mergers, where extreme conditions allow for the fusion of lighter elements into heavier ones.
