cds-question@unistra.frvisible-astronomysloan-photometryasteroidsColors of trans-Neptunian objects (TNOs) are used to study the evolutionary processes of bodies in the outskirts of the solar system and to test theories regarding their origin. Here I describe a search for serendipitous Sloan Digital Sky Survey (SDSS) observations of known TNOs and Centaurs. I present a catalog of SDSS photometry, colors, and astrometry of 388 measurements of 42 outer solar system objects. I find weak evidence, at the {approx} 2{sigma} level (per trial), for a correlation between the g - r color and inclination of scattered disk objects and hot classical Kuiper Belt objects. I find a correlation between the g - r color and the angular momentum in the z direction of all the objects in this sample. These findings should be verified using larger samples of TNOs. Light curves as a function of phase angle are constructed for 13 objects. The steepness of the slopes of these light curves suggests that the coherent backscatter mechanism plays a major role in the reflectivity of outer solar system small objects at small phase angles. I find weak evidence for an anticorrelation, significant at the 2{sigma} confidence level (per trial), between the g-band phase-angle slope parameter and the semimajor axis, as well as the aphelion distance, of these objects (i.e., they show a more prominent "opposition effect" at smaller distances from the Sun). However, this plausible correlation should be verified using a larger sample. I discuss the origin of this possible correlation and argue that if this correlation is real it probably indicates that "Sedna"-like objects have a different origin than other classes of TNOs. Finally, I identify several objects with large variability amplitudes.2012ApJ...749...10Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/749/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2013)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/A+A/522/A93 : Short-term variability of 29 minor planets (Thirouin+, 2010)J/ApJS/189/336 : HST astrometry of TNOs (Benecchi+, 2010)J/A+A/508/451 : Light curves of 5 Trans-Neptunian Objects (Perna+, 2009)J/AJ/133/26 : Solar phase curves of distant icy bodies (Rabinowitz+, 2007)J/A+A/468/L13 : Photometry of the trans-Neptunian object 2005FY9 (Ortiz+, 2007)http://www.sdss.org/ : SDSS home pagehttp://www.minorplanetcenter.net/ : Minor Planet Center home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/749/10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/749/10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/749/10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/749/10https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/749/10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/749/10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/749/10/SDSS-obs (Astrometric and photometric measurements of the solar system objects identified in SDSS images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/749/10/SDSS-obs?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/749/10/SDSS-obs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/749/10/SDSS-obs?GETtext/xml+votable180.050000true24.9094511114.267753890.0055555555555555565/5798 6/0 4319 4394 4396 4481 4663 4710 4714 4753 4800 4921 17748 17749 17753 17756 17777 17806 17815 17857 17920 17981 18007 18009 18017 18018 18019 18022 18023 18024 18025 18034 18062 18063 18075 18081 18083 18084 18086 18176 18177 18178 18235 18393 18767 18774 18775 18776 18777 18794 18834 18835 18849 18851 18852 18853 18854 18859 18862 18864 19007 19025 19031 19035 19036 19037 19038 19050 19058 19085 19086 19090 19091 19092 19093 19096 19107 19108 19200 19201 19456 19457 19458 23181 23196 23197 23198 23202 23203 23208 23209 26202 26337 26957 26959 26999 27296 27422 27444 27596 30034 30035 30043 30065 30101 30102 36731 36811 368612.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/749/10?format=asciiOpticaldefaultJ/ApJ/749/10/SDSS-obsAstrometric and photometric measurements of the solar system objects identified in SDSS imagesrecnoRecord number assigned by the VizieR team.
