Scientific paper

30 Doradus in the Large Magellanic Cloud is the nearest giant H II region. It provides a unique opportunity to study the interactions between a large number of massive stars and the interstellar medium. It contains large shell structures that emit bright diffuse X-rays and show shocked material at DeltaV up to 300 kms. HST WFPC2 images only exist for the central 2min point5 of 30 Dor, where the interstellar and stellar conditions are vastly different from those in the supershells in outlying regions. Therefore, we request WFPC2 images of three of these shells in the H Alpha S II and O III emission lines. With the high spatial resolution we can for the first time image SNR shocks in superbubbles, study the cloudy medium of a giant H II region, map cloud-cloud collisions, model a supershell around a cluster, and search for circumstellar shells around massive stars.
