GENERAL FORM Proposal 1213c PI: Sara R. Heap Proposal Title: THE NUCLEUS OF M83: CYCLE-1 EARLY ACQUISISTION IMAGES ------------------------------------------------------------------------------------ 1.

Rubin CARNEGIE INSTITUTE OF WASHINGTON USA Eliot Malumuth COMPUTER SCIENCES CORP. USA William Waller NASA, GODDARD SPACE FLIGHT USA CENTER ------------------------------------------------------------------------------------ 3. Description of proposed observations. During Cycle 1, we will obtain U, R, H-alpha, and I-band pictures of the nucleus of M83. We will use these pictures choose the starburst areas for observing in Cycle 2 (GTO augmentation time). We will identify "blue" (starburst) regions by their colors, while H-alpha will reveal H II regions near the nucleus. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The HST is necessary for access to the ultraviolet (where the stellar wind features are found) at high angular resolution. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. The PC pictures will be used to construct a photometric and astrometric map of the nuclear regions of M83. Subsequent FOS spectra of selected nuclear starburst regions will be analyzed in order to deduce the stellar content. ------------------------------------------------------------------------------------ 13. We propose to use the HST/PC and FOS to investigate the nucleus of M83, a barred spiral galaxy whose nucleus has both normal and starburst characteristics. ------------------------------------------------------------------------------------ 11.
