These observations will provide for the first time a complete line_9: study of the young massive stellar population and of the interstellar dust line_10: extinction outside our Galaxy. ! ! end of abstract general_form_proposers: lname: LEQUEUX fname: JAMES inst: MARSEILLE OBSERVATORY country: FRANCE esa: X ! lname: DEHARVENG fname: J. mi: M. inst: MARSEILLE OBSERVATORY country: FRANCE esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: 1) 6 positions in M33 and IC1613 line_2: f/96, ID-zoom, 1800s (F165W, F320W, F430W) line_3: Note: a) ID-zoom is to increase the FOV (F320W is not available at f/48) line_4: b) the first exposure is duplicated with neutral density filter for line_5: calibration purpose. line_7: 2) 1 position in outer part of NGC5457 (M101) line_8: f/48, 2900s (F195W), 2500s (F430W) line_10: 3) 6 positions in M33 and IC1613 line_11: f/96, objective prism in far UV, 1800s broad constraints on orientation to line_12: avoid crowding by bright stars. ! question: 4 section: 1 line_1: The study of young stellar populations in nearby galaxies (for instance M33, (m line_2: - M)_0 = 23.8) requires high angular resolution to resolve stars down to about line_3: M_V = -1 in crowded fields and UV response to select and classify the hot line_4: stars. These two characteristics are only provided by the FOC. ! question: 7 section: 1 line_1: To be done at LAS VAX. ! question: 10 section: 1 line_1: Data analysis capabilities (VAX) line_2: Research assistance ! question: 13 section: 1 line_1: It is proposed to observe star formation regions in several nearby spiral and line_2: irregular galaxies (present candidates being M33, IC1613 and M101). line_3: Observations with the FOC at f/96 through three filters, including a far UV line_4: filter, will overcome confusion problems and provide a statistics for hot stars line_5: yielding the luminosity function and the upper initial mass function. line_6: Observations with the far UV objective prism will allow to determine the far UV line_7: extinction law, and may be, the hydrogen column density and, hence, the gas to line_8: dust ratio.
