Photometric study of the OB star clusters NGC 1502 and NGC 2169 and mass estimation of their members at the University Observatory Jena
M. M. Hohle, T. Eisenbeiss, M. Mugrauer +7
In this work we present detailed photometric results of the trapezium like galactic nearby OB clusters NGC 1502 and NGC 2169 carried out at the University Observatory Jena. We dete…
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…
Transit observations at the observatory in Grossschwabhausen: XO-1b and TrES-1
M. Vanko, St. Raetz, M. Mugrauer +9
We report on observations of transit events of the transiting planets XO-1b and TrES-1 with the AIU Jena telescope in Grossschwabhausen. Based on our IR photometry (in March 2007)…
