It's luminosity and it's temperature.
Main sequence stars are bigger.
A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime. Our Sun is a yellow dwarf in "main sequence".
A star's position on the main sequence indicates its mass, temperature, luminosity, and evolutionary stage. Stars fuse hydrogen into helium in their cores while on the main sequence. The more massive the star, the hotter, brighter, and shorter its lifespan.
As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
Any star that it fusing hydrogen into helium is classed as a main sequence star.
main sequence stars , our sun is also a main sequence star
After the main sequence, a star becomes a red giant.

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.
main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
Main sequence stars that are most massive are O-type stars, which can be more than 16 times the mass of the Sun. These stars are among the hottest and brightest in the main sequence and have relatively short lifespans compared to lower mass stars.
