What gases make the main sequence star?
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]
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 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.
What is the nearest star in the main sequence is?
Most stars are on the main sequence; that includes red dwarves. Specifically, in this case, the closest known star - Proxima Centauri - is also the closest main-sequence star.
The star Algol is estimated to have approximately the same luminosity as the star Aldebaran and approximately the same surface temperature as the star Rigel Algol is best classified as a?
Algol is a blue main-sequence star in the constellation Perseus
What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
