abstract:

    line_1:        It is proposed to study the origin of the UV flux in elliptical-type
    line_2:        population and to determine the respective contribution from young
    line_3:        stars and from hot evolved stars. Two SO galaxies NGC 5102 and NGC
    line_4:        3115, at reasonable distance and with very different gas contents,
    line_5:        have been selected. Observations through several filters
    line_6:        (especially a far UV filter) will allow to resolve and study the
    line_7:        massive stars, if they exist. The UV surface brightness of the
    line_8:        unresolved background will be measured and will set constraints on
    line_9:        the characteristics of hot evolved stars.

  question:        3
    section:       1
    line_1:        It is proposed to observe the two galaxies with the UV filter
    line_2:        F175W in order to reveal the massive and young stars if any;
    line_3:        a complementary observation of NGC 5102 is made with the filter
    line_4:        F320W and F320W+F4ND+F1ND (at f/96). A dwarf elliptical is observed
    line_5:        for comparison with the F175W filter.
    line_6:        NOTE: Due to problems with image shift and elongated PSF in F320W
    line_7:        we have requested to change to F342W and we have been granted permission
    line_8:        to make this change by STScI ( Nolan Walborn ) on 20 Sept., 1994. We
    line_9:        have just made a straight substitution of F342W for F320W. No other
    line_10:       changes are required.

  question:        4
    section:       1
    line_1:        The high spatial resolution of the FOC will provide the possibility to resolve
    line_2:        the young and massive stars, if they exist, in two examples of relatively
    line_3:        nearby elliptical-type population. This capability is further improved by the
    line_4:        good response of the FOC in the ultra-violet. At these wavelengths, the
    line_5:        contrast of young and hot stars would be enhanced against the contribution of
    line_6:        the main-sequence and giant-branch components of the old stellar population.
