abstract:

    line_1:        The extended chromosphere and circumstellar shell of the M supergiant
    line_2:        Betelgeuse will be studied through HRS spectroscopy of the Mg II resonance
    line_3:        lines, FOS spectra, and WF/PC images of the shell. The results will provide
    line_4:        new insights into mass loss by the star.

  question:        3
    section:       1
    line_1:        These exposures on Betelgeuse are coupled to others in proposals by K.
    line_2:        Carpenter (HRS team) and by O. Engvold, K. Moe, G. Weigelt and D.L. Lambert
    line_3:        (FOC proposal).
    line_5:        The HRS echelle exposure of the Mg II h and k lines should be made at the same
    line_6:        time as Carpenter's series of exposures.
    line_8:        The FOS spectra should follow observation and preliminary analysis of the FOC
    line_9:        images to be obtained by Engvold et el.
    line_11:       The PC images may be also obtained following the FOC images. However, it is
    line_12:       not absolutely essential that they be so phased.
    line_14:       Any Cycles
    line_16:       comment continued from TF target number 2: , Weigelt and Lambert as authors.
    line_18:       comment continued from EL Page 9, Line 4.000: the images will be apportioned.
    line_20:       comment continued from EL Page 10, Line 13.000: or just off the CCD. The longer
    line_21:       exposures should permit the shell to be detectable to 20" from the star.

  question:        4
    section:       1
    line_1:        HST provides the necessary spatial resolution, access to the ultraviolet and
    line_2:        key spectral lines, and a low background for the detection of the faint shell.

!

  question:        7
    section:       1
    line_1:        Observations as provided by standard STScI software will be analyzed at the
    line_2:        University of Texas. HRS/FOS spectra of the chromosphere will be analyzed in
    line_3:        collaboration with J. Linsky and K. Carpenter (JILA).
    line_5:        FOS spectra and WF/PC images will be discussed in collaboration with O.
    line_6:        Engvold, K. Moe and G. Weigelt.

  question:        13
    section:       1
    line_1:        HRS and FOS spectra including the Mg II h and k lines will be obtained of
    line_2:        Betelgeuse's extended chromosphere. WF/PC images of the large circumstellar
    line_3:        shell will be obtained. The goal is to study mass loss from this supergiant.
