Category:Main sequence stars
Main sequence stars, also called dwarf stars, are stars that fuse hydrogen in their cores. These are dwarfs in that they are smaller than giant stars, but are not necessarily small. For example, a blue type O dwarf star is brighter than most red giants.
There are also other objects called dwarfs like white dwarfs and black dwarfs. They are not main sequence stars but stellar remnants instead. Unlike true stars, brown dwarfs have too little mass to sustain nuclear fusion so they do not belong to this category either. The border between the lowest-mass main sequence stars and brown dwarfs is somewhat ambiguous.
