abstract:

    line_1:        We propose to take advantage of the very high resolution, sensitivity and
    line_2:        attenuation capabilities of the FOC in its coronographic mode to search for
    line_3:        planets of other stars, in order to get direct proof of their existence and to
    line_4:        obtain data on the formation of planetary systems. Stars like Eps Eri and
    line_5:        Barnard's are prime candidates for this search, because they are close to the
    line_6:        Sun and their motion seems to be perturbed by unseen low-mass companions. The
    line_7:        FOC is very suited to carry out the search, thanks to the photon counting
    line_8:        capabilities, to the high attenuation of the coronograph, and to the small
    line_9:        pixel size resolving the structure of the PSF of the bright primary star. A
    line_10:       roll-blinking technique will be used to improve the detection capabilities.

  question:        3
    section:       1
    line_1:        This program is a very difficult one; being largely of exploratory nature it
    line_2:        requires a flexible schedule, with real time decisions. Because the objects we
    line_3:        are looking for are extremely faint, the finalisation of the observing strategy
    line_4:        depends on the actual performance of ST+FOC+HRA, namely on the results of
    line_5:        the SV phase. These considerations mean that the targets, exposure times and
    line_6:        priorities in the Exposure Logsheets are our present best guesses. The target
    line_7:        list comprises a few more objects than observable in the allocated time of 24h,
    line_8:        in order to incorporate in the final scheme information that might come in the
    line_9:        near future from ground observations. The total exposure time in the logsheet
    line_10:       (26.8h instead of 24h) is determined by the inclusion of Prior.3 targets that
    line_11:       may substitute for others not feasible in the GTO.
    line_12:       The observing procedure ROLL is described in detail in Sect.2.

  question:        4
    section:       1
    line_1:
    line_3:        ST is necessary to:
    line_4:        -provide the highest contrast star/companion,
    line_5:        -reach the 27th-28th V-mag
    line_6:        Diffraction-limited performances, absence of atmospheric turbulence and
    line_7:        diffuse luminosity, extremely accurate tracking all are requisite for a
    line_8:        successfull outcome of this program.

!

  question:        5
    section:       1
    line_1:        The program is largely of exploratory nature; it also requires a very precise
    line_2:        centering of the bright star under the coronographic finger. Real-time
    line_3:        examination and decisions during at least the first exposures (for each target)
    line_4:        are therefore required. Dark time is absolutely necessary. Flexible schedule
    line_5:        is desirable to accomodate unforeseen discoveries (such as a companion much
    line_6:        brighter than expected).

!

  question:        6
    section:       1
    line_1:        Dark time absolutely necessary in order to reach the faintest magnitudes and to
    line_2:        be able to properly cancel the wings of the bright star luminosity profile

!

  question:        7
    section:       1
    line_1:        Real-time analysis is particularly important to: properly center the star under
    line_2:        the finger; decide on any correction; quickly rotate and add and subtract
    line_3:        sub-exposures; evaluate the statistical significance of any clump of photons
    line_4:        indicating the presence of a faint companion; decide on the continuation or not
    line_5:        of an exposure; etc. Off-line analysis includes refined algorithms for best
    line_6:        geometrical and photometric operations; evaluation of celestial coordinates;
    line_7:        etc. This complex of operations should be carried out as quickly as possible
    line_8:        not only for a particular target, but also to optimize the following
    line_9:        observations.
    line_10:       Therefore it is likely that a lengthy stay at the StSci and an heavy use of its
    line_11:       image-processing facilities are required.

!

  question:        8
    section:       1
    line_1:        The program aims at the direct detection of sub-stellar companions of nearby
    line_2:        stars like EPS-ERI and Barnard's, by making use of the diffraction figure of ST
    line_3:        and of the high resolution, sensitivity and attenuation capability of the
    line_4:        FOC/288 HRA mode.
    line_5:        A ST roll-blinking technique can be used to improve the detection
    line_6:        capabilities.

!

  question:        10
    section:       1
    line_1:        VAXES and MIDAS, + STARLINK + ASTRONET, HP1000+ IHAP available to PI and
    line_2:        coworkers

!

  question:        13
    section:       1
    line_1:        We propose to search for planets around nearby stars with the FOC in its
    line_2:        coronographic configuration. A roll-blinking technique will be used to improve
    line_3:        the detection capabilities.
