Research subject for a potential FP6 project

CCD photometry and astrometry of asteroids and comets using 0.61-m telescope at the Skalnate Pleso Observatory. Theoretical investigation of transfer orbits among different populations of small bodies in the Solar System regarding near-Earth objects. Investigation of activity of selected cometary nuclei and its influence on physical and dynamical evolution of these bodies, possible candidates on near-Earth objects.
Analysis of the structure and dynamics of meteoroid streams and their association with other minor bodies of the Solar System. Investigation of the meteoroid population in the vicinity of the Earth\'s orbit, including the mass distribution of particles in meteor streams and sporadic background, the determination of the internal structure of streams, their aging and decay.Identification of the filamentary structure of selected meteor showers and study of the meteor sporadic background activity by the forward scatter radio system operating over the triangle Lecce-Bologna-Modra.
Analysis of the cosmic dust particles provided by the NASA to determine their composition and physical properties. Results can be used for the study of their behaviour in planetary atmospheres and interplanetary space, especially their dynamics and reflection conditions and a better understanding of the desintegration processes.
