Karazin Kharkiv National University popup.description2  Research is devoted to study physical and dynamic properties of asteroids. The aim is to carry out spectrophotometric and polarimetric observations of selected asteroids, which can be iron-rich in their composition, thermal modelling and estimation of masses of M-type asteroids. Research methods include spectrophotometric and polarimetric telescopic observations, numerical modeling, analytical calculations, comparative analysis of the obtained data. We obtained new observational data on the phase dependences of brightness in the visible wavelengths for 5 M-type asteroids, new high-precision lightcurves for 9 asteroids, and new observational data on polarimetric properties for 7 M-type asteroids; we found two subgroups of asteroids with different polarimetric parameters among the main-belt M-type asteroids: obtained new estimates of masses and densities for 10 asteroids classified as M-type; determined the orbital parameters of the first iron meteorite with instrumentally documented fall; Found the correspondence of age estimates for families of M-type asteroids and some groups of iron meteorites. We improved an analytical model for asteroid mass estimated from the value of Yarkovskiy's effect. Product Description popup.authors Golubov Oleksiy A. Kyrylenko Ihor I Krugly Yuri M.
