. Oey's research group, Feedback Activity in Nearby Galaxies (FANG), focuses on massive star feedback to the interstellar and intergalactic medium, on a local, global and cosmic scale. These feedbacks include: * Radiative feedback: HII regions, Lyman continuum-emitting galaxies * Chemical feedback: Enrichment processes and galactic chemical evolution * Kinematic feedback: Supernova-driven superbubbles and galactic superwinds * Massive star and clusters Finding no star bigger than 200 solar masses, she and her colleagues at the University of Michigan at Ann Arbor have found evidence for a size limit in a survey of other clusters within our galaxy and in the nearby satellite galaxy, Magellanic clouds. "It is not clear whether the size is limited by the physics of star formation or by the size of the parent gas cloud. Larger stars, perhaps of up to 500 solar masses, may have existed in the early universe," Oey says.
