The research of this group led by Petr Kabath is dedicated to detection of exoplanets via spectroscopy and to detection and characterization of exoplanetary atmospheres. The group use spectroscopic method of measurement of radial velocities to detect and characterize exoplanetary systems. The group also use large telescope facilities such as ESO or IAC (Spain) but also Ondřejov Perek 2-m telescope equipped with a Echelle spectrograph.
The main targets of the group are planetary candidates detected by Kepler/K2 and later TESS space missions. Currently, the members ogf the group are working on the project of refurbishment and installation of a new spectrograph (PLATOSpec) at 1.52-m telescope at ESO La Silla Observatory. This project should serve as a ground absed support for future space mission PLATO. In addition, the group is also detecting and characterizing exoplanetary atmospheres by using large telescopes mainly at ESO observatories. The group is coordinating an ERASMUS+ grant for which a public lecture series is planned.
