Principal Investigator Institution Country Telephone Prof. C. R. O'dell RICE UNIVERSITY USA 713-527-8101X3 ------------------------------------------------------------------------------------ 7. Abstract Under the assumption that the Oort Cloud of comets is a common feature of stars with planetary systems. We will look for cometary objects in NGC 7293, the closest planetary nebula. This is approved proposal Z112. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 5311 PI: Prof. C. R. O'dell Proposal Title: OORT CLOUD IN PLANETARY NEBULAE ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Pi C. R. O'Dell 3240 USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. Images with emission line filters will be made with WFPC2 of a region in NGC 7293 known to be rich in cometary forms. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. Only the HST allows the high angular resolution needed for this program. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. These observations should be scheduled close in time with similar observations made under GTO program 5086. ------------------------------------------------------------------------------------ 9. Description of previous HST work. We have reduced and analyzed two sets of multifilter observations of the Orion nebula. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). The principal resources at Rice University are the Image Lab and availability of graduate students. ------------------------------------------------------------------------------------ 11.
