Space.com: There is a type of star that continues to accrete gas even as it shines. Such stars are 10 times as massive as the Sun and most active in the UV spectrum. The common models for star formation show that the radiation those stars emit should push the protostellar gas away from the star. But with young massive stars, that is not what has been observed. Now Mac Low of the American Museum of Natural History and his colleagues have created a model in which the gas around the star has denser pockets and filaments that absorb most of the radiation, which shields the gas farther from the star.
