Вивчення фізичних властивостей, форми, розмірів та інш. астероїдів, що зближаються з Землею. Head Lupishko D., Registration Date 25-03-2002 Organization Kharkov National University named after V.N.Karazin popup.description2 Object of research - main belt asteroids; asteroids which approach with the Earth; comets. The purpose of work - definition of star sizes, parameters of color, parameters of polarization, the sizes, the form, parameters of the axial reference and optical characteristics of asteroids of the main belt and near to an orbit of the Earth; studying of optical properties of comets and a nature of dust particles of their atmospheres. Methods of research - photometric and polarimeter pervision and mathematical modelling. Photometric supervision of 21-st asteroid and polarimeter and photometric supervision of one comet are carried out. Star sizes, parameters of color, curve shine and amplitude of shine of asteroids are received. Cycle times of four asteroids for the first time are calculated. Phase dependence of polarization of comet C/2001 A2 (LINEAR) is received. Streams of molecular issues and a continuum and efficiency of gas and a dust, color and the attitude a gas / dust of a comet are designed. Resultsof researches represent significant interest from the point of view of fundamental science and problems " Asteroid danger ". The received curves of shine and parameters of polarization of asteroids will enter the International databases " Asteroid Photometric Catalogue " and " Planetary Data System ".
