Astronomers crack mystery of the "monster stars"
Theory suggests that stars can't form that are more massive than 150
solar masses. However, stars as massive as 300 solar masses have been found in some star forming regions of the Large Magellanic Cloud. Was star forming theory wrong, or is there another explanation for why these stars are so much more massive?

Yup, it's not just their gravity you have to take into account, you also have to factor in their repulsive forces from stellar winds, and light pressure prior to collision. Then once they have made initial contact, you would need to factor in the repulsion from their convective zones against each other, and then their radiative zones, and finally their cores would not be joining together without a big spiralling fight either.
