چکیده
Context. The populations of small bodies the Solar System (asteroids, comets, Kuiper-Belt objects) are used to constrain origin and evolution System. Both their orbital distribution composition required track dynamical pathway from regions formation current locations. Aims. We aim at increasing sample objects that have multi-filter photometry compositional taxonomy. Methods. search for moving in archive Sloan Digital Sky Survey. attempt maximizing number detections by using loose constraints on extraction. then apply a suite filters remove false-positive (stars or galaxies) mark out spurious astrometry. Results. release catalog 1 542 522 entries, consisting 036 322 observations 379 714 known unique SSOs together with 506 200 sources not linked any SSOs. completeness is estimated be about 95% purity above

The Sloan Digital Sky Survey
The Sloan Digital Sky Survey (SDSS) will carry out a digital photometric and spectroscopic survey over π steradians in the northern Galactic cap. An array of CCD detectors used in drift-scan mode will image the sky in five passbands to a limiting magnitude of r′ ∼ 23. Selected from the imaging survey, 10 galaxies, 10 quasars and selected samples of stars will be observed spectroscopically. In a...
متن کاملThe Sloan Digital Sky Survey
The Sloan Digital Sky Survey is an ambitious, multi-institutional project to create a huge digital imaging and spectroscopic data bank of 25% of the celestial sphere, approximately 10,000 deg2 centred on the north galactic polar cap. The photometric atlas will be in 5 specially-chosen colours, covering the π ster of the Survey area to a limiting magnitude of r′∼23.1, on 0′′ . 4 pixels, resultin...
متن کاملChandra Observations of Red Sloan Digital Sky Survey Quasars
We present short Chandra observations of twelve bright (i<18) zem∼1.5 quasars from the Sloan Digital Sky Survey chosen to have significantly redder optical colors than most quasars at the same redshift. Of the five quasars with optical properties most consistent with dust reddening at the quasar redshift, four show indirect evidence of moderate X-ray absorption (inferred NH∼ 10 22 cm) with a du...
متن کاملEvidence for asteroid space weathering from the Sloan Digital Sky Survey
By studying color variations between young and old asteroid families we find evidence for processes that modify colors of asteroids over time. We show that colors of aging surfaces of S-type asteroids become increasingly ‘redder’ and measure the rate of these spectral changes. We estimate that the mean spectral slope between 0.35 and 0.9 μm increases with time t (given in My) as ≈ 0.01 μm−1 × l...
متن کاملThe shapes of galaxies in the Sloan Digital Sky Survey
We determine the underlying shapes of spiral and elliptical galaxies in the Sloan Digital Sky Survey Data Release 6 from the observed distribution of projected galaxy shapes, taking into account the effects of dust extinction and reddening. We assume that the underlying shapes of spirals and ellipticals are well approximated by triaxial ellipsoids. The elliptical galaxy data are consistent with...
