High resolution spectroscopy of exoplanets - tool for characterization
Dupkala, Daniel ; Kabáth, Petr (advisor) ; Mikšovský, Jiří (referee)
We observed 211 spectra of transiting exoplanet MASCARA-2b (also known as KELT-20b) with OES echelle spectrograph installed at Perek telescope at Astronomical Institute of Czech Academy of Sciences. All data were acquired in 2018. From the total number of observed frames 100 were acquired during transit phase. Spectroscopic time series taken during transit can reveal characteristics of the exoplanet itself. In this work we will present data reduction of the echelle spectroscopy along with analysis of the reduced data. We discuss suitability of the data from Perek telescope for further characterization of exoplanetary systems. We will present the detection limits in this work. Expected aim is to understand the systematic errors and the data sets from Perek telescope in general and their suitability for spectroscopic follow-up in the era of bright TESS exoplanet host stars. 1
Automation of processing and photometric data analysis for transiting exoplanets observed with ESO NIR instrument HAWK-I
Blažek, M. ; Kabáth, Petr ; Klocová, Tereza ; Skarka, Marek
Nowadays, when amount of data still increases, it is necessary to automatise their processing. State-of-the-art instruments are capable to produce even tens of thousands of images during a single night. One of them is HAWK-I that is a part of Very Large Telescope of European Southern Observatory. This instrument works in near-infrared band. In my Master thesis, I dealt with developing a pipeline to process data obtained by the instrument. It is written in Python programming language using commands of IRAF astronomical software and it is developed directly for “Fast Photometry Mode” of HAWK-I. In this mode, a large number of data has been obtained during secondary eclipses of exoplanets by their host star. The pipeline was tested by a data set from sorting of the images to making a light curve. The data of WASP-18 system contained almost 40 000 images observed by using a filter centered at 2.09 μm wavelength and there is a plan to process other data sets. A goal of processing of WASP-18 and the other data sets is consecutive analysis of exoplanetary atmospheres of the observed systems.
