The study of exoplanets and protoplanetary discs in the Main astronomical observatory of NAS of Ukraine

Abstract

Long-term spectral and photometric observations of transit and nontransit exoplanet systems are carried out in MAO NAS of Ukraine. On the base of obtained data we study the influence of exoplanets on chromospherical activity of the host stars, model the light curves, calculate exoplanet system's parameters and search planets in eclipsing binary star's systems. In the field of protoplanetary disc researches it was developed a new algorithm for calculation of the energy distribution in spectra of systems containing a spherical central source and a surrounding protoplanetary disc.
