Information × Registration Number 0211U000452, 0109U007536 , R & D reports Title Spctrophotometric research of stellar systems with transiting extrasolar planets. popup.stage_title Head Kuznetsova Yuliana, Registration Date 07-02-2011 Organization Main Astronomical Observatory popup.description2 Photometric observed data for 11 stars having extrasolar transit planets (TrES-1, TrES-2, TrES-3, WASP-10, HAT-P-19, CoRoT-2, GJ1214, WASP-2, WASP-3, HAT-P-10, HD 189733), obtaining in Crimea astrophysical observatory (CrAO) with help of 38-cm telescope by Cassegrain system, in Terskol observatory (Russia) - with help of ZEISS-600, MEADE and Celestron-11 telescopes, in the Astronomical Institute of Slovak Academy of Sciences (Tatranska Lomnica) - with help of 50-cm telescope by Newton system. Spectroscopic observed data with high resolution for transit system HD189733 obtaining in Terskol observatory (Russia) with help of ZEISS-2000 and coude echelle spectrometer with high resolution (R = 45000) and in Crimea astrophysical observatory (CrAO) with help of 2.6-m G.A.Shajn telescope. Numerous light curves for each object as graphic dependence of brightness variability of system "star+extrasolar planet" on time during transit evidence were done using photometric observations. Graphic dependences of radiation intensity from wavelength and their time variations were done using spectroscopic observations. Some radiation variations in continuum and in several powerful spectral lines (Н-alpha, Н and К Са, double Na) were fixed. Profile variations of noted lines and their equivalent widths were found.
