What is the name for the portion of a stars life cycle when it is using hydrogen for fuel?
white dwarf
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
Main Sequence.
What is the name for the portion of a star's life cycle when it is using hydrogen for fuel?
main sequence
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
What gas makes up the majority of an old star?
Even in an old star just before it explodes, the majority of the star in hydrogen gas. But as the hydrogen is fused, the helium residue begins to interfere with the hydrogen fusion, like ashes in the bottom of a fireplace.
What is major gas in a star?
Stars are made mostly of hydrogen though there are many other elements that help to build one. And toward the end of its life cycle a star will actually be made of a large portion of helium as well which it will begin to fuse, along with hydrogen or instead of hydrogen, in its core.
What is the main fuel of stars?
The main fuel of stars is the most fundamental element in the universe -- hydrogen. Most stars spend most of their lives fusing hydrogen into helium. Only later in life do they fuse helium into heavier elements, and continue to fuse lighter nuclei into the elements up through iron. (According to many scientists, nickel really does not "count" in this chain for reasons that require an understanding of nuclear physics.)
A hypergiant star will most likely follow which series of stages during its' life?
All stars spend the majority of their lives on the main sequence. Once high mass stars have exhausted the hydrogen fuel in their cores they expand into much larger red or blue supergiant stars.
Nearly 90 percent of all-stars are at what point in their life cycles?
90% of all stars are at mid-life where their cores are fusing hydrogen into helium.
What is in the first stage in a stars life cycle?
A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
What stars have the longer life span?
The smaller stars generally live longer due to less mass & less hydrogen is burned.
What Fuel does a Star burn to create its own energy?
A star will use fusion to combine lighter atoms into heavier atoms. A main-sequence star (that's the majority of stars) will convert hydrogen-1 into helium-4, so in this case, hydrogen-1 is the fuel. Once it starts running out of hydrogen-1, it will start fusing the helium into heavier elements - in which case the main fuel will be the helium-4. Later in the life cycle of a star, the fuel can be even heavier elements.
