cds-question@unistra.frsolar-systemasteroidsinfrared-astronomyspectroscopyKnowledge of water in the solar system is important for the understanding of a wide range of evolutionary processes and the thermal history of the solar system. To explore the existence of water in the solar system, it is indispensable to investigate hydrated minerals and/or water ice on asteroids. These water-related materials show absorption features in the 3um band (wavelengths from 2.7 to 3.1um). We conducted a spectroscopic survey of asteroids in the 3um band using the Infrared Camera (IRC) on board the Japanese infrared satellite AKARI. In the warm mission period of AKARI, 147 pointed observations were performed for 66 asteroids in the grism mode for wavelengths from 2.5 to 5um. According to these observations, most C-complex asteroids have clear absorption features (>10% with respect to the continuum) related to hydrated minerals at a peak wavelength of approximately 2.75um, while S-complex asteroids have no significant features in this wavelength range. The present data are released to the public as the Asteroid Catalog using AKARI Spectroscopic Observations (AcuA-spec).2019PASJ...71....1Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/71/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/71/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/71/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/71/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/71/1https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/71/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/71/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/71/1/target (Target list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/71/1/target?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/71/1/target?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/71/1/target?GETtext/xml+votable180.050000true162.901517.38950.005555555555555556AKARI6/83 267 428 444-445 1056 1157 4277 4279 4407 4527 5135 6170 16689 17054 17263 17290 17343 17374 17383 17454 17609 17630 17916 18102 18150 18162 18220 18317 18385 18445 18702 18736 18818 18956 18969 19277 19761 19932 22640 22642 24235 25770 25819 25867 25924 26044 26274 26739 26930 27189 27387 27407 27725 28198 28300 30767 44164 44249 44490 44512 44527 44804 44982 48546 48556 48595 48610 48616 48849 48922https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/71/1?format=asciiInfrareddefaultJ/PASJ/71/1/targetTarget listrecnoRecord number assigned by the VizieR team.
