Based on astronomical records, the reasons why there is main sequence are:

There is a relationship between the luminosity and temperature of hydrogen-burning stars.
Hydrogen-burning stars reach an equilibrium between the inward gravitational pull on their atoms and the outward pressure of their hot gases, which are heated by energy produced in nuclear reactions.
There is a relationship between the luminosity and mass of hydrogen-burning stars.

What is a star?

A star can be defined as a giant astronomical or celestial object that comprises a luminous sphere of plasma and it is bounded together by its own gravitational force.

Generally, a star is typically made up of two (2) main hot gases and these include the following:

Hydrogen (H)

Helium (He)

What is a main sequence?

A main sequence refers to a type of star that fuses hydrogen in its core and it has a stable balance of outward pressure as a result of core nuclear fusion and gravitational forces that are pushing inward.
