cds-question@unistra.frsolar-systemasteroidsspectroscopyThe search for asteroidal parent bodies of chondrites through various techniques is an ongoing endeavor. A link between ordinary chondrites (OCs) and S-type asteroids has previously been established by the sample return of the Hayabusa space mission. OCs are the class with the most abundant samples in our meteorite collection. We present an in-depth study of the reflectance spectra of 39 equilibrated and 41 unequilibrated ordinary chondrites (EOCs and UOCs). We demonstrate that consistent measuring conditions are vital for the direct comparison of spectral features between chondrites, otherwise hampering any conclusions. We include a comparison with a total of 466 S-type asteroid reflectance spectra from various databases. We analyze (i) if a difference between EOCs and UOCs as well as between H, L and LL can be seen, (ii) if it is possible to identify unequilibrated and equilibrated S-type asteroid surfaces and (iii) if we can further constrain the match between OCs and S-type asteroids all based on reflectance spectra2022Icar..38115012Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Icar/381.K5012CatalogResearchIsServedByTAP VizieR generic 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/other/Icar/381.K5012https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Icar/381.K5012http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Icar/381.K5012https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Icar/381.K5012https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Icar/381.K5012http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Icar/381.K5012GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/other/Icar/381.K5012/tableSpectral parameters measured on the reflectance spectra of S-types asteroidsrecnoRecord number assigned by the VizieR team.
