cds-question@unistra.frsolar-systemasteroidsCeres is the largest and most massive body in the asteroid main belt. Observational data from the Dawn spacecraft reveal the presence of at least two impact craters about 280km in diameter on the Ceres surface, that could have expelled a significant number of fragments. Yet, standard techniques for identifying dynamical asteroid families have not detected any Ceres family. In this work, we argue that linear secular resonances with Ceres deplete the population of objects near Ceres. Also, because of the high escape velocity from Ceres, family members are expected to be very dispersed, with a considerable fraction of km-sized fragments that should be able to reach the pristine region of the main belt, the area between the 5J:-2A and 7J:-3A mean-motion resonances, where the observed number of asteroids is low. Rather than looking for possible Ceres family members near Ceres, here we propose to search in the pristine region.2016MNRAS.458.1117Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/1117CatalogResearchIsServedByTAP 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/MNRAS/458/1117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/1117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/1117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/1117https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/1117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/1117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/458/1117/table1Photometric and albedo Ceres family candidates in the pristine region with D<20kmEccEccentricitysrc.orbital.eccentricitydoublesiniSine of inclination, sin(i)src.orbital.inclinationdoubleHAbsolute H magnitudemagphys.magAbsfloatDiamEstimated diameter (km)kmphys.angSizefloatTypePhotometric (SDSS) or albedo (WISE) C-type candidatemeta.codecharrecnoRecord number assigned by the VizieR team.
