runaway star
subject			fact

runaway star	has spectral type O star, B star
	has definition Early type star (O and early B) outside the Galactic plane, which reached large distances (from the Galactic plane) because of their high velocities.
	has definition Star of spectral type O or early B with unusually high space velocities. Runaway stars are thought to be produced when there is a supernova explosion in a close binary system.
