The Radial and Rotational Velocity of Ophiuchi
T. Zehe, M. Mugrauer, R. Neuhäuser +5
We present the results of our spectroscopic monitoring campaign of Oph, carried out at the University observatory Jena with the spectrograph FLECHAS between July 2015 and Septe…
Radial velocity measurements and orbit determination of eight single-lined spectroscopic binary systems
R. Bischoff, M. Mugrauer, T. Zehe +7
Since early 2015 a new radial velocity monitoring campaign is going on at the University Observatory Jena. The aim of this project is to obtain current radial velocity measurements…
Long-Term Photometry of IC 348 with the YETI Network
D. J. Fritzewski, M. Kitze, M. Mugrauer +29
We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…
Search for transiting exoplanets and variable stars in the open cluster NGC 7243
Z. Garai, T. Pribulla, L. Hambálek +23
We report results of the first five observing campaigns for the open stellar cluster NGC 7243 in the frame of project Young Exoplanet Transit Initiative (YETI). The project focuses…
Ground-based transit observations of the HAT-P-18, HAT-P-19, HAT-P-27/WASP-40 and WASP-21 systems
M. Seeliger, M. Kitze, R. Errmann +46
As part of our ongoing effort to investigate transit timing variations (TTVs) of known exoplanets, we monitored transits of the four exoplanets HAT-P-18b, HAT-P-19b, HAT-P-27b/WASP…
No variations in transit times for Qatar-1 b
G. Maciejewski, M. Fernández, F. J. Aceituno +11
The transiting hot Jupiter planet Qatar-1 b was presented to exhibit variations in transit times that could be of perturbative nature. A hot Jupiter with a planetary companion on a…
