GIARPS (GIAno & haRPS) is a project devoted to have on the same focal station
of the Telescopio Nazionale Galileo (TNG) both the high resolution
spectrographs HARPS-N (VIS) and GIANO (NIR) working simultaneously. This could
be considered the first and unique worldwide instrument providing
cross-dispersed echelle spectroscopy at a high resolution (R=115,000 in the
visual and R=50,000 in the IR) and over in a wide spectral range (0.383 - 2.45
micron) in a single exposure. The science case is very broad, given the
versatility of such an instrument and the large wavelength range. A number of
outstanding science cases encompassing mainly extra-solar planet science
starting from rocky planet search and hot Jupiters, atmosphere characterization
can be considered. Furthermore both instrument can measure high precision
radial velocity by means the simultaneous thorium technique (HARPS - N) and
absorbing cell technique (GIANO) in a single exposure. Other science cases are
also possible. Young stars and proto-planetary disks, cool stars and stellar
populations, moving minor bodies in the solar system, bursting young stellar
objects, cataclysmic variables and X-ray binary transients in our Galaxy,
supernovae up to gamma-ray bursts in the very distant and young Universe, can
take advantage of the unicity of this facility both in terms of contemporaneous
wide wavelength range and high resolution spectroscopy.Comment: 8 pages, 5 figures, SPIE Conference Proceeding
