Intense ultraviolet radiation is not commonly associated with the star formation process. It is more commonly associated with the later stages of a star's life when it has reached the main sequence and is fusing hydrogen into helium in its core. During the star formation process, a protostar is still accumulating mass and has not yet achieved nuclear fusion in its core, so it does not emit significant amounts of UV radiation.
