abstract:

    line_1:        The goals of this program are to determine the physical characteristics of the
    line_2:        winds/chromospheres around cool luminous stars.  GHRS observations of the
    line_3:        C II (UV 1) 1335 A and (UV 0.01) 2325 A multiplets will be used along with
    line_4:        observations of the C I lines near 1655 and 1994 A to constrain the temperatures
    line_5:        and densities in model chromospheres.  The C II (UV 0.01) lines will also be
    line_6:        used to estimate the turbulence in these chromospheres.   The (confusing) far UV
    line_7:        spectrum of the M supergiants will be explored with the GHRS.
    line_8:        GHRS observations of Fe II lines will be used to study the dependence of
    line_9:        the wind velocity on radial distance above the photosphere.
    line_10:       High quality Fe II and Mg II profiles will be
    line_11:       acquired to search for discrete velocity features and the presence of
    line_12:       circumstellar absorption within the profiles.
    line_13:       The photospheric absorption-line spectrum (2579-2675 A) of Arcturus will be
    line_14:       observed in the echelle mode.  Medium resolution observations of Fe II and
    line_15:       Mg II in the dusty, very luminous star Mu Cep will provide information on the
    line_16:       effect of dust and very low gravity on the wind velocity field.
    line_17:       *** this file contains the Cycle 1 observations only ***

  question:        4
    section:       1
    line_1:        The data required for this program consists of UV spectra not obtainable from
    line_2:        the ground. IUE has been used for a preliminary reconnaissance of all these
    line_3:        targets, except for AlphaSco A (which has a hot companion that cannot be
    line_4:        excluded from the larger IUE apertures). We now require the higher sensitivity,
    line_5:        wavelength resolution, and S/N attainable with the HRS and ST to improve and
    line_6:        extend our studies of the physical conditions characterising the outer
    line_7:        atmospheres of these cool luminous stars. Only HRS is capable of providing us
    line_8:        with the very high precision line profiles, fluxes, and absolute velocities
    line_9:        required for our program.

  question:        6
    section:       1
    line_1:        Wavelength calibration exposures for all the echelle observations are needed to
    line_2:        provide us with a velocity scale accurate to about 1 km/sec. This accuracy is
    line_3:        required to allow us to study the dependence of the wind flow velocities on
    line_4:        distance above the photosphere of each star.

!

  question:        7
    section:       1
    line_1:        The data will be reduced and analyzed primarily with in-house software
    line_2:        developed for analysis of IUE data and with new software to be developed
    line_3:        in-house. Software developed by the GHRS IDT and the proposers will be
    line_4:        used in the reduction and analysis of these observations.  The NLTE
    line_5:        MULTI code will be used to construct model chromospheres and spectra which
    line_6:        will be compared with the observations.
    line_7:        References documenting the methods of analysis to be used in this investigation
    line_8:        are given in the Scientific Justification section of this proposal.

    line_3:        1. Alpha Ori

    line_5:        3. Gamma Cru    (this is the only Cycle 1 target)

    line_7:        5. Alpha Boo
    line_8:        6. Lambda Vel
    line_9:        7. Mu Cep

  question:        13
    section:       1
    line_1:        We plan UV spectroscopic observations with GHRS of a sample of 7 cool luminous
    line_2:        stars. Our goals are to determine, from analysis of chromospheric emission
    line_3:        lines, the physical conditions in their wind regions/chromospheres and to study
    line_4:        the dependence of wind velocity on radial distance above the photosphere.  The
    line_5:        UV photospheric absorption line spectrum of Arcturus will also be studied at
    line_6:        very high resolution.
