From a magnitude-limited infrared survey of the 30 Doradus complex four candidate protostars are identified. These are associated with dense knots in the nebular arcs, and have luminosities of 10,000-50,000 solar luminosities and masses of solar masses. The results indicate that both the knots and the associated star formation are likely to be caused by the compression of interacting arcs of mass-loss winds from hot massive stars in the central cluster, and other nearby clusters. This mode of star formation differs from the classical star formation scenario within dense molecular clouds, and appears to be highly efficient. The present new data confirm the spatial separation of the young blue and older red stars, and provide further evidence for a multiple-starburst origin for the 30 Doradus region. The qualitative similarity of the structure of the central cluster to the structure of the LMC blue globulars has been noted previously. The brightness distribution and number counts are used to investigate the structure quantitatively.
