7. Abstract
Models of the diffuse interstellar medium still lack definite observational proofs,
in particular on small scale lengths (<10pc).  They predict interfaces between cold
dense clouds and a hot "coronal" very tenuous widely spread phase.  These interfaces
need to be directly obseved and studied because they offer a unique chance to
understand the role of shocks, the nature of the evaporation zones, the grain
destruction, the extent of the warm gas phase.  All these problems can only tackled
in details in the very local interstellar medium where the low column-densities of
individual absorption regions are not hidden and can be well enough located. From
ground-based studies, we have pointed out a new image of the nearby instellar
medium.  At least four velocity components are present within 20 pc. For two of
them, we were able to delineate approximate frontiers toward which it is very
promissing to search for interfaces.  Furthermore, we found some evidence for a
temperature structure within one of these components, providing therefore a prime
target. Since visual observations do not offer adequate diagnostic lines and
available UV data do not have the needed spectral resolution, we propose to perform
with HRS a much more complete physical study of the cold and warm local gas.  The
selected diagnostic lines are those of AlII, FeII, MnII, MgI, and CIV, to be
observed toward nearby stars in directions where confusion betwee

  3. Description of proposed observations.
  The target stars were carefully selected,owing to ground based studies. Through
 exposures with ECH-B at 2346A (Fe II), 2596A (Fe II, Mn II), 2852A (Mg I), 1859A
 (Al III) and with G160M at 1671A (Al II), and using the profile fitting method,
 we will find the detailed velocity structure of the line of sight, the neutrals
 behaviour and will have access to temperature, electron density, ionization state
 and depletion informations. The 1550A line (C IV) will reveal the hotter phases
 of the local ISM; being wider, the G160M resolution is still adequate. G160M
 spectra will be also completed to evaluate more precisely the scattered light
 levels. All the observations are made in the accumulation mode through the 0.25
 arc sec science aperture, still usable for our very bright targets, to keep the
 resolution, with a S/N ratio of at least 100. No unusually stringent requirements
 are foreseen, although we need accurate heliocentric velocity scales; for this,
 we add wave lamp calibrations at each wavelength and at each about 20 min during
 long exposures.
------------------------------------------------------------------------------------
  4. Justification of need for HST observations.
  The proposed programme can only be achieved by observing resonance lines of
 different elements in various stages of ionization, which are only available in
 the UV. High spectral resolution is mandatory in order to resolve the velocity
 structure of the lines of sight, to measure b-values of 0.5 km/s (1/10 of the
 spectral resolution corresponding to 500K in the case of Mg), i.e. to study
 individual absorbing regions. Copernicus studies were limited to O and B stars at
 more than 50pc. IUE does not provide the spectral resolution needed. Ground based
 telescopes provide the spectral resolu- tion but not adequate diagnostic lines.
 Nevertheless our extensive optical studies have revealed the compexity of the
 local ISM and the most suitable regions where to search for interfaces of diffuse
 interstellar clouds, and regions where the overlaps in the velocity space will be
 minimized.
------------------------------------------------------------------------------------
  5. Description of special scheduling requirements.
  This study requires a survey type program. In order to minimize the number of
 exposures we selected only 6 ECH grating positions, distributed among the target
 stars according to their brightness. All fluxes are estimated from published
 direct UV observations or from similar scaled stars. Account has been taken for
 the scattered light, for the ripple function and for the decreased stellar flux
 in the wings of broad stellar lines when appropriate. As an example, consider the
 Al III line toward Beta Car. The flux at 1859A is 86E-11 erg/cm2/s/A. The new OTA
 + 2.0" aperture + GHRS ECH-B system sensitivity is 1.6E+11, the scattered light
 is 0.15 and the ripple is 0.84. This leads to a 408s exposure to reach a S/N of
 100.
                                                                  Page   3
------------------------------------------------------------------------------------
  6. Description of special calibration exposures.
  Because we need the best possible accuracy in velocities, we will complete a
 spectral calibration at each setting of the HRS instrument and every about 20 min
 during long exposures. To reach a better evaluation of the scattered light in the
 echelle modes, we plan lower resolution spectra with an holographic grating. Two
 exposures for determining the instrumental profile are also performed. Standard
 procedures are used to resolve the photocathode granularity problem along with
 sub-stepping to improve the spectral resolution, and take care of the geomagnetic
 drift. Images of the aperture are also required in order to improve the
 wavelength scale. Because this is time consuming, we assumed that no changes
 should appear over successive orbits. We thus required NO GAP between
 observations completed on a given star. Also some observations are required to be
 sche- duled within 30min to link them as tightly as possible.
------------------------------------------------------------------------------------
  7. Data reduction and analysis plans.
  We will make use of the Routine Science Data Processing and of the Calibration
 Data Base Software. We will make additional use of the Science Data Analysis
 System (SDAS) at the Institute, or of the MIDAS system available at our
 Institute. We have ready access to good computational facilities at our home
 institution for any further analysis. This includes, in particular, the profile
 fitting program initially built for analysing Copernicus data.
------------------------------------------------------------------------------------
 10. Resources to be supplied by investigator's institution(s).
  As indicated in item 7, extensive data analysis capabilities exist at our home
 institutions. All proposers are appointed by CNRS or CEA in France.
