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…
Large dust gaps in the transitional disks of HD 100453 and HD 34282
S. Khalafinejad, K. M. Maaskant, N. Marinas +1
The formation of dust gaps in protoplanetary disks is one of the most important signposts of disk evolution and possibly the formation of planets. We aim to characterize the 'flari…
The center-to-limb variation across the Fraunhofer lines of HD 189733; Sampling the stellar spectrum using a transiting planet
S. Czesla, T. Klocová, S. Khalafinejad +2
The center-to-limb variation (CLV) describes the brightness of the stellar disk as a function of the limb angle. Across strong absorption lines, the CLV can vary quite significantl…
