What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
Why must a star convert helium after it has converted all of its hydrogen to helium?
Helium is the star's source of energy and if it has no energy the star would die.
Does a white dwarf star use hydrogen for energy?
No. A white dwarf is the remnant of a star in which fusion has stopped. There is no hydrogen left. All the energy left in a white dwarf is residual heat.
Why is the sun or the star eventually die?
A star eventually uses up all of it's hydrogen in nuclear fusion. They fusion of hydrogen into helium is what makes the star glow bright and hot. When all the helium is fused, the star collapses inward on itself, and becomes a small "white dwarf" star, essentially a pile of "stellar embers". That's the end of a star's life.
What is a medium size yellow star composed mostly of hydrogen and helium?
All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.

What happens with all your membership items when you lost your membership on star wars clone wars adventures?
That's a question that you should ask yourself
What happens when all 3 isotopes of hydrogen react with chlorine in sunlight?
It forms hydrogen chloride
When a low mass star first runs short of hydrogen in its core it becomes brighter because?
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
What type of star used up all of its hydrogen and its leftover center of an older star?
this is called a white dwarf

When does fusion of hydrogen atoms happens?
under extreme heat and pressure - it happens on the sun all the time!
