Karazin popup.description2 The object of study - the main belt of asteroids; Trojans asteroids, Kuiper belt bodies , comets . The goal of research - determination of absolute magnitudes, color indices, the size, shape parameters of axial rotation, optical and structural properties of the surfaces of asteroids and Kuiper belt bodies; identification and study of asteroids among multiple systems, optical and physical characteristics of the atmospheres of comets. Research methods - photometric and polarimetric observations , numerical modeling, data integration. During 258 nights the photometric observations of 74 main belt asteroids, 7-trans-Neptunian objects, two comets, one of the largest bodies of the Kuiper belt - Makemake and polarimetric observations at 8-m telescope of the ESO (Chile) of six Jupiter Trojans were carried out. On the base of obtained observational data the physical, geometrical and optical properties of these objects were determined. It identified seven multiple systems among small asteroids (D<15 km) of the main belt (among them there are two triple and five double systems) and indicated the most probable mechanism of their origin. At the 8-m ESO VLT telescope (Chile) the first polarimetric observations of the Jupiter Trojans were conducted. The obtained data suggest that these objects are likely relict bodies, not captured from the outer part of the protoplanetary disk at an early stage of the Solar system evolution. An international program of observations of Kuiper belt object 2005 FY9 (Makemake) with five observatories in the world was undertook and period of rotation and shape elongation of the body were determined. The monitoring activity of the comet C / 2006 S3 (LONEOS) in the frame of international observation program showed that this comet is one of the most active objects in the Solar system. It is shown that the slope of spectral dependence of asteroid polarization degree change its sign at the transition from negative to positive polarization of polarization-phase curve.
