cds-question@unistra.frasteroidsultraviolet-photometryWe present ultraviolet (UV) photometry (near-UV (NUV) band, 180-280nm) of 405 asteroids observed serendipitously by GALEX from 2003 to 2012. All asteroids in this sample were detected by GALEX at least twice. Unambiguous visible-color-based taxonomic labels (C type versus S type) exist for 315 of these asteroids; of these, thermal-infrared-based diameters are available for 245. We derive NUV-V color using two independent models to predict the visual magnitude V at each NUV-detection epoch. Both V models produce NUV-V distributions in which the S types are redder than C types with more than 8{sigma} confidence. This confirms that the S types' redder spectral slopes in the visible remain redder than the C types' into the NUV, this redness being consistent with absorption by silica-containing rocks. The GALEX asteroid data confirm earlier results from the International Ultraviolet Explorer, which two decades ago produced the only other sizeable set of UV asteroid photometry. The GALEX-derived NUV-V data also agree with previously published Hubble Space Telescope (HST) UV observations of asteroids 21 Lutetia and 1 Ceres. Both the HST and GALEX data indicate that NUV band is less useful than u band for distinguishing subgroups within the greater population of visible-color-defined C types (notably, M types and G types).2015ApJ...809...92Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/809/92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2014)II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)J/AJ/150/75 : Asteroid light curves from PTF survey (Waszczak+, 2015)J/ApJ/749/10 : SDSS observations of Kuiper belt objects (Ofek, 2012)J/ApJ/741/68 : Main Belt asteroids with WISE/NEOWISE.
