O-type star

An O-type star is a classification of star.

In 2256, the USS Discovery jumped into the vicinity of an O-type star using the spore drive, instead of the intended destination Corvan II. 

The Idran system was a trinary star system consisting of a central supergiant star (FGC-1215) and twin O-type companions. 

In 2375, the corona of an O-type star in the Delta Quadrant served to contain the explosion of a Malon export vessel, that otherwise would have destroyed everything within three light years. The USS Voyager directed the vessel into the star with a series of tractor pulses, once it seemed that its away team would not be able to avert the explosion.
