cds-question@unistra.frasteroidsinfrared-photometryvisible-astronomybroad-band-photometryWe present visible (BVRI) photometric measurements of 27 Trans-Neptunian objects, obtained with the FORS2 instrument on the ESO/8m Very Large Telescope (Unit 2) from runs during September and November 2000. The objects display a broad and continuous range of colors from neutral-bluish to very red. Most of the objects also have a linear reflectivity spectrum over the VRI range. There is no evidence of a bimodal color distribution as has been previously reported by other groups. Several objects (1994 TB, 1995 SM_55_, 1998 UR_43_, 1999CF_119_ and 2000 OK_67_) show evidence of changing color, and should be investigated further. The object 1995 SM_55_ deserves a more complete study since its neutral-blue colors suggest it could be a good candidate for hosting cometary activity.2001A&A...380..347Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/380/347CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/113/115 : Photometry and analysis of 27 asteroids (Lagerkvist+, 1995)J/A+A/375/275 : Asteroidal I, J, K in the DENIS Survey (Baudrand+ 2001)VII/108 : Asteroid II data base, Version March 1988 (Lagerkvist+, 1987)B/astorb : Orbits of Minor Planets (Bowell 2001)VII/91 : IRAS Asteroid and Comet Survey (Veeder+ 1986)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/380/347https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/380/347http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/380/347https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/380/347https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/380/347http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/380/347GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/380/347/table2Magnitudes obtained for Run 1 and 2 using a fixed aperture diametere_Vmag? rms uncertainty on Vmagmagstat.errorfloatnullablerecnoRecord number assigned by the VizieR team.
