Class O type stars are the most luminous and massive main sequence stars in the galaxy. They range in mass from 15 to 90 solar masses and burn very brightly indeed, with a surface temperature reaching 52,000 K so appear very blue. They are very short lived with lifetimes of 1 - 10 million years, ending in supernova.
The term dwarf star refers to a variety of distinct classes of stars. The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars - classified as K and M in the Harvard scheme - could be divided into two distinct groups. They are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them "giant" and "dwarf" stars, the dwarf stars being fainter and the giants being brighter than the sun.
