abstract:

    line_1:        We propose to make a direct imaging of the disk observed around the
    line_2:        star 68 Oph at the Pic du Midi Observatory. The high quality data
    line_3:        produced by the high resolution of the anti-blooming WFPC2
    line_4:        will permit to reach 3 goals: i) as 68 Oph is the component of a binary
    line_5:        system, with the WFPC2 it will be possible to measure the
    line_6:        characteristics of the binary (separation and position angle) as well
    line_7:        as to make an accurate photometry of the two components; ii) the inner
    line_8:        boundary of the disk will be directly observed with short exposure
    line_9:        times; iii) long exposure times will probe its outer
    line_10:       extension. The same observations will be done on the reference star
    line_11:       4 Aql which pictures will be used for the data reduction.
    line_12:       Besides, we propose to detect the
    line_13:       possible gaseous disk around Oph 68 through very sensitive UV spectral
    line_14:       signatures with the unprecedented resolution and sensitivity of the
    line_15:       GHRS. This is absolutely needed to provide disk hydrodynamical models
    line_16:       and disk interacting with binaries models with new sets of data and to
    line_17:       study the only one complementary example of proto-planetary disk to
    line_18:       the BETA-Pictoris one.

  question:        3
    section:       1
    line_1:        We propose to observe 68 Oph with a NaI filter in order to
    line_2:        reduce contrast between star and disk and also to reduce the
    line_3:        blooming of WFPC2 in the central part of the star. We propose to use
    line_4:        WFPC2 with the anti-blooming mode. The width of the filter is chosen
    line_5:        to have 1 000000 e- (maximum of e- per pixel) per second in the
    line_6:        central part of the star. The exposure time is computed to reach m=7
    line_7:        arcsec-2 at the maximum of dynamic. The number of exposures is chosen
    line_8:        to reach m=16 arcsec-2 (estimated brightness of the disk at 2 arcsec
    line_9:        from the star) with S/N=10. We can expand the magnitude of detection
    line_10:       by binning pixels to reach a value of m=20 arcsec-2 (estimation of
    line_11:       the brightness at 10 arcsec of the star). As the central part of the
    line_12:       image is strongly over exposed an important amount of light will be
    line_13:       present over all the CCD. Thus a very good knowledge of the PSF is
    line_14:       needed. To detect a possible dust signature,
    line_15:       we propose to use a filter centered
    line_16:       close to 2000A. We can also study the dust albedo by using narrow
    line_17:       filters centred on U,B,V,R, and I. Anti-blooming observations of Beta
    line_18:       Pictoris showed changes of albedo between different filters,
    line_19:       particularly closer to the star (Vidal-Madjar et al., 1992). From the
    line_20:       results in these different filters it may be possible to compare the
    line_21:       dust albedo to the one of different asteroidal or meteoritic materials
    line_22:       (Gaffey M.J., Mc Cord T.B., 1979, in: Asteroids, 688, eds T.Gehrels).

  question:        3
    section:       2
    line_1:        In order to have an estimation of the physical circumstellar matter
    line_2:        we will observe the FeII, MgII and MnII lines. The MgII and FeII lines
    line_3:        will be done for the two stars of the binary. If the furthest one is
    line_4:        behind the disk we will then have a direct access to the circumstellar
    line_5:        material by comparing the two results. Otherwise, we will obtain a
    line_6:        measure of ISM.

!

  question:        4
    section:       1
    line_1:        Our extensive ground based survey with a similar technique as the one we
    line_2:        proposed to use with the WFPC2 (anti-blooming mode) showed that it was
    line_3:        difficult to get closer than 1.5 arcsec to the star. The corrected ST
    line_4:        PSF allows now to get much closer to the central star in a way clearly
    line_5:        impossible from the ground. Also the furthest extend of the disk can
    line_6:        only be observed from space where the contrast with the sky background
    line_7:        is more favorable.
    line_8:        The observations of the disk close to the star are only possible with
    line_9:        the HST WFPC2. The possible hole in the dust disk can only be imaged
    line_10:       with our technique (WFPC2 with anti-blooming mode).
    line_11:       As far as spectrophotometry is concerned, although a lot could be done
    line_12:       from the ground, as we have demonstrated for BETA-Pictoris, it is clear
    line_13:       that having access to essentially only the CaII H and K lines is a
    line_14:       strong limitation. Besides, IUE presents too severe limitations in both
    line_15:       resolution and S/N to allow a very good data acquisition, especially in
    line_16:       the case of the fainter companion of 68 Oph. The FeII line should
    line_17:       permit to have access to characteristics of the disk by comparing the
    line_18:       results for 68 Oph and for its companion. The MgII and MnI lines will
    line_19:       give us information about the density, temperature, composition and
    line_20:       distribution of the circumstellar material. It is clear that any
    line_21:       ground-based or IUE observing plan could never give such informations
    line_22:       and our recent observations of BETA-Pictoris proved to be
    line_23:       very efficient.

    line_19:       of falling and evaporating bodies on to the star and revealed clearly
