Spins, shapes, and orbits for near-Earth objects by Nordic NEON

摘要: The Nordic Near-Earth-Object Network (NEON) observing program accrues knowledge about the physical and dynamical properties of near-Earth objects (NEOs) using state-ofthe-art inverse methods. Photometric astrometric observations are being carried out at Optical Telescope. Here, NEON from June 2004 - September 2006 reviewed. Statistical orbital inversion is illustrated by application so-called Volume-of-Variation method to observations. Spins shapes characterized shape models that allow analytical computation disk-integrated brightnesses in arbitrary illumination observation geometries for Lommel-Seeliger Lambert scattering laws. treatment allows error analyses spins large numbers discrete sample solutions statistical problem. Currently, spin have been derived 2002 FF12, 2003 MS2, RX7, HW as well (1685) Toro (1981) Midas. For (1862) Apollo, an unambiguous solution has obtained convex method.
