Abstract While our specific understanding of the proto-planetary disks in Orion is increasing, our general knowledge of what promotes and hinders their birth and longevity is hampered by having good observations in only this one region. Observations of proplyds in other regions with different conditions of ultraviolet irradiation and age can provide more stringent tests of our present models. We have therefore designed an ACS/WFC and parallel WFC2 survey of open clusters embedded in H II regions that, with a small number of orbits, maximizes the probability of succesfully finding proplyds there. Our observing strategy will additionally afford a quantitative study of the detected proplyds, as well as the derivation of a correlation between those characteristics and the clusters' stellar population. ACS gives us an unprecedented opportunity to kick start the mass discovery of proplyds in many environments, an obvious way in which progress can be made in this field. This small tailored survey, gives us an excellent chance to obtain a huge return at low cost. ------------------------------------------------------------------------------------ 9857( 3) - 05/07/03 10:57 - [ 2] Observations Description ------------------------ ACS/WFC images will be taken of 6 locations in 5 OB open clusters. In parallel, WFPC2/WF will be obtained. OREINT angle ranges are specified to maximize the science.
