Student se seznámí s dostupnou literaturou. Následně zpracuje spektroskopická data z OES spektrografu a vypracuje analýzu dat. Zejména nás zajíma Rossiter-McLaughlin efekt, radiální rychlosti, zjištění hvězdných parametrů ze spekter a odhad detekčních limitů pro případnou detekci exo-atmosfér.
We observed about 300 spectra of transiting planets MASCARA-2b, MASCARA-1b and KELT-9b and with OES echelle spectrograph installed at Perek telescope. The data were acquired during 2017-2018 period. For all planets we obtained several nights of spectroscopic data also during the transit. Spectroscopic time series taken during transit can reveal characteristics of the exoplanet itself. In this work, we will present the data reduction of the echelle spectroscopy along with the analysis of the reduced data in order to detect exoplanetary signature. Main focus is the factors which influence detection of exo-atmospheres rather than detection itself. We will present the detailed telluric lines analysis and detection limits in this work. Expected aim is to understand the systematic errors and in general the data sets from Perek telescope and their suitability for spectroscopic follow-up in the era of bright TESS exoplanet host stars.
