LH54-425 is a star system that was identified as a spectroscopic binary by astronomer Pablo G. Ostrov in 2002. It is located in the LH 54 OB association within the Large Magellanic Cloud[4] Both members are O-type stars and the pair is among the most massive known. They are emitting a stellar wind with a velocity of 2,800 km/s.[3] As the pair evolve, they may merge to form a single star with a mass 80 times that of the Sun. In time, they will explode as a core-collapse supernova.[5]
