The results of processing and analysis of spectral observations of exoplanet system HD189733 are presented in the paper. The system consists of spectral type K1-K2 star and one extrasolar planet transiting across the star disk. Four object spectra were obtained with spectral resolution R = 45 000. High resolution coude-echelle spectrograph locating on the 2-meter mirror telescope Zeiss-2000 at the peak Terskol Observatory was used. It was detected increasing of depth and equivalent width of absorbing lines Hα, Hβ, Hγ, Hδ, H & K CaII, Na I D2 & D1 in spectra obtaining during transit and directly after that as compared with spectra obtaining during 30 minutes immediately before transit. Central emissions in H & K CaII lines were detected in all obtaining spectra.

Главная астрономическая обсерватория НАН Украины Проведен анализ кривых блеска затменной двойной системы HS 2231+2441, полученных при помощи 36-см телескопа. Методом тайминга затмений получено свидетельство в пользу существования в системе третьего тела.
