abstract:

    line_1:        The goal of this WF/PC project is to extend our knowledge of young
    line_2:        stellar systems by looking more closely at the R136 cluster in the
    line_3:        30 Doradus Nebula of the Large Magellanic Cloud.  The resolution that
    line_4:        the HST provides will allow us to probe the central regions of the
    line_5:        cluster and thus more completely sample its color-magnitude diagram and
    line_6:        luminosity function.  We will use the augmentation time to improve
    line_7:        photometry of the brightest stars and extend the color and magnitude
    line_8:        limits 2-3 mag fainter, with the goal of reaching stars still
    line_9:        approaching the main sequence.  Information on the age and evolution
    line_10:       of this cluster may help us better understand the IMF in the LMC
    line_11:       and in such stellar systems.

  question:        3
    section:       1
    line_1:        A series of observations will be taken in four wide bandpass
    line_2:        filters to provide a large dynamic range in colors similar to
    line_3:        the broadband UBVR system. Thus, we will produce accurate
    line_4:        photometry of the brightest giants and will be able to probe
    line_5:        the fainter end of the color-magnitude diagram of the cluster.
    line_6:        Additional narrow-band images will reveal HII line emitters in
    line_7:        the cluster.

  question:        4
    section:       1
    line_1:        The highest possible visible resolution of HST is crucial to
    line_2:        separating the core stars of R136a over more than the 2-3
    line_3:        mags dynamic range available to speckle, while obtaining
    line_4:        accurate photometry and spectral identification as well.
    line_5:        Moreover, the fainter population within and around R136 requires
    line_6:        the sharp core PSF to detect, and HST exceeds by a factor of
    line_7:        three the resolution available on the ground.

  question:        7
    section:       1
    line_1:        Standard photometric reduction will be done using a version
    line_2:        of DAOPHOT residing in VISTA.
