Photometric analysis of the eclipsing binary 2MASS 19090585+4911585
St. Raetz, M. Vanko, M. Mugrauer +11
We report on observations of the eclipsing binary 2MASS 19090585+4911585 with the 25 cm auxiliary telescope of the University Observatory Jena. We show that a nearby brighter star…
Planetary transit observations at the University Observatory Jena: TrES-2
St. Raetz, M. Mugrauer, T. O. B. Schmidt +14
We report on observations of several transit events of the transiting planet TrES-2 obtained with the Cassegrain-Teleskop-Kamera at the University Observatory Jena. Between March 2…
Variability of young stars: Determination of rotational periods of weak-line T Tauri stars in the Cepheus-Cassiopeia star-forming region
A. Koeltzsch, M. Mugrauer, St. Raetz +11
We report on observation and determination of rotational periods of ten weak-line T Tauri stars in the Cepheus-Cassiopeia star-forming region. Observations were carried out with th…
Planetary transit observations at the University Observatory Jena: XO-1b and TrES-1
St. Raetz, M. Mugrauer, T. O. B. Schmidt +9
We report on observations of transit events of the transiting planets XO-1b and TrES-1 with a 25 cm telescope of the University Observatory Jena. With the transit timings for XO-1b…
Photometric monitoring of the young star Par 1724 in Orion
R. Neuhaeuser, A. Koeltzsch, St. Raetz +12
We report new photometric observations of the 200000 year old naked weak-line run-away T Tauri star Par 1724, located north of the Trapezium cluster in Orion. We observed in the br…
New brown dwarf candidates in the Pleiades
T. Eisenbeiss, M. Moualla, M. Mugrauer +11
We have performed deep, wide-field imaging on a ~0.4 deg^2 field in the Pleiades (Melotte 22). The selected field was not yet target of a deep search for low mass stars and brown d…
