Above 100 such objects were discovered by scientists for the last years. Their characteristics have many coincidences with those of Solar system giant planets but at the same time they have some differences. To fill up the theory of planetary systems formation including our own Solar system and to investigate the physical and optical properties of new planets there were carried out experimental and theoretical researches. There were obtained following results: 1 - Based on earlier obtaned high-resolution spectral data for solar system giant planets (Jupiter, Saturn) there were carried out researches of theirs atmospheric spectra for the purpose of numerical and qualitative estimation of raman scattering on the hydrogen and helium molecules. Also for these planets are calculated spactral brightness coefficients in visual range of wavelengths with sharply detailed specialities of raman light scattering. 2 - There are considered main principles of nonlinear effects formation in the planet atmosphere and obtained indications for existence such nonlinear optical effect as secondary harmonical frecuency for main moleculas absorbtion bands of methant and ammonia in spectral range 350-500 nm in the Jovian and Saturnian spaectra. 3 - There are obtained spectral data with help of the high-resolution coude echelle spectrometer fed by the 2-m telescope at the Terskol observatory (Nothern Caucasus) for series of solar type stars with planets; data are processed; there are carrying out researches of their spectra with aim to find Raman scattering and to more precise definition of chemical composition of extrasolar giant planet atmospheres. 4 - There are realizated theretical calculations for estimation of comtribution of scattering radiation by planet atmosphere to visual and close IR spectral ranges. 5 - There are prepared new redaction of data base of molecular lines HITRAN.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
