Ondr}ejov echelle spectrograph, ground based support facility for exoplanet missions
Petr Kabath, Marek Skarka, Silvia Sabotta +18
Fulfilling the goals of space-based exoplanetary transit surveys, like Kepler and TESS, is impossible without ground-based spectroscopic follow-up. In particular, the first-step ve…
Lack of close-in, massive planets of main-sequence A-type stars from Kepler
Silvia Sabotta, Petr Kabath, Judith Korth +5
Some theories of planet formation and evolution predict that intermediate-mass stars host more hot Jupiters than Sun-like stars, others reach the conclusion that such objects are v…
X-ray emission in the enigmatic CVSO 30 system
S. Czesla, P. C. Schneider, M. Salz +3
CVSO 30 is a young, active, weak-line T Tauri star; it possibly hosts the only known planetary system with both a transiting hot-Jupiter and a cold-Jupiter candidate (CVSO 30 b and…
Time-resolved UVES observations of a stellar flare on the planet host HD 189733 during primary transit
T. Klocova, S. Czesla, S. Khalafinejad +2
HD 189733 is an exoplanetary system consisting of a transiting hot Jupiter and an active K2V-type main sequence star. We aim to use VLT/UVES high resolution echelle spectra to stud…
Exoplanetary atmospheric sodium revealed by the orbital motion. Narrow-band transmission spectroscopy of HD 189733b with UVES
S. Khalafinejad, C. von Essen, H. J. Hoeijmakers +8
During primary transits, the spectral signatures of an exoplanet atmosphere can be measured using transmission spectroscopy. The goal of this work is to accurately measure the atom…
YETI observations of the young transiting planet candidate CVSO 30 b
St. Raetz, T. O. B. Schmidt, S. Czesla +32
CVSO 30 is a unique young low-mass system, because, for the first time, a close-in transiting and a wide directly imaged planet candidates are found around a common host star. The…
