What two gases are a main sequence star made of?
Hydrogen and helium
When does a protostar becomes a main sequence star?
As the gases in a protostar begin to collapse, the central core begins to heat up due to pressure. As more gases are absorbed, the greater the pressure. Once the temperature of the core reaches 10 million degrees K, hydrogen fusion begins, and the star begins it's life on the main sequence. The star will stay on the main sequence whilst it still has hydrogen to fuse. Once all the hydrogen has been used, the star will drop out of the main sequence. Protostar stage in the stellar evolution. [See related question]
What is the main predictor of where a star will spend most of the time on the main sequence and why?
The star's mass. More mass will make the star hotter, and will increase the pressure in the center; this will make the star burn its fuel faster.When a star is on the "main sequence", it burns hydrogen-1, converting it into helium-4.
Is a main sequence star part of the sun?
Yes, the sun is a main sequence star. Main sequence stars are those, like the sun, that are fusing hydrogen into helium in their cores. This is the main stage of a star's life cycle when it is in a stable state.
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
Main sequence star distance from earth?
The sun is a main sequence star, so 1 AU.
What is a stabilized star?
Main-Sequence star
What gases make up the star denebola?
Wikipedia lists it as a main sequence star. That means that it still has significant amounts of hydrogen. Main sequence stars also typically have a smaller amount of helium (remember, the hydrogen gradually converts to helium), and even smaller amounts of the so-called "metals" (i.e., all other elements).
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
Why is Sirius not a main sequence star?
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
What is the main characteristic of a sequence star?
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
