Tohoku-Hiroshima-Nagoya planetary spectra library: a method for characterizing planets in the visible to near infrared
Context: A comprehensive framework for comparing spectral data fromdifferent planets has yet to be established. This framework is neededfor the study of extrasolar planets and objects within the solarsystem. Aims: We completed observations to compile a libraryof planet spectra for all planets, some moons, and some dwarf planets inthe solar system to study their general spectroscopic and photometricnatures. Methods: During May and November of 2008, weacquired spectra for the planets using TRISPEC, which is capable ofsimultaneous three-band spectroscopy across a wide wavelength range of0.45-2.5 ?m with low resolving power (?/?? ~140-360). Results: Patterns emerge when comparing thespectra. By analyzing their general spectroscopic and photometricnatures, we show that it is possible to distinguish between gas planets,soil planets, and ice planets. These methods can be applied toextrasolar observations acquired using low resolution spectrography orbroad-band filters. Conclusions: The present planet spectrallibrary is the first library to contain observational spectra for all ofthe solar system planets, based on simultaneous observations at visibleand near infrared wavelengths. This library will be a useful referencefor analyzing extrasolar planet spectra and calibrating planetary datasets.THN Planet spectra library is only available in electronic form at theCDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/507/1649
