The 43 pages that link to Main sequence, each with the reason it gives.
Stellar massRelated: Mass largely determines a main-sequence star’s luminosity and lifetime.
CNO cycleRelated: CNO fusion supplies core energy in sufficiently hot main-sequence stars.
Stellar ageRelated: A star’s position and evolution along this phase constrain its age.
StarRelated: Most stars spend the majority of their lifetimes in this phase.
O-type starRelated: Most O-type stars spend their brief, luminous lives on the main sequence.
Omega CentauriRelated: Its turnoff in the cluster’s color-magnitude diagram constrains stellar ages.
Blue supergiantRelated: Massive stars can evolve from the main sequence into blue-supergiant states.
Red-giant branchRelated: Stars enter the red-giant branch after core hydrogen fusion ends.
FomalhautRelated: Fomalhaut is a young A-type star still burning hydrogen on the main sequence.
Yellow supergiantRelated: Yellow supergiants have evolved beyond this hydrogen-burning phase.
