The Araucaria Project: A study of the classical Cepheid in the eclipsing binary system OGLE LMC562.05.9009 in the Large Magellanic Cloud
Wolfgang Gieren, Bogumil Pilecki, Grzegorz Pietrzynski +26
We present a detailed study of the classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009. The Cepheid is a fundamental mode pulsator w…
The Araucaria Project. Precise physical parameters of the eclipsing binary IO Aqr
D. Graczyk, P. F. L. Maxted, G. Pietrzynski +11
Our aim is to precisely measure the physical parameters of the eclipsing binary IO Aqr and derive a distance to this system by applying a surface brightness - colour relation. Our…
The Araucaria Project: The distance to the Carina Dwarf Galaxy from infrared photometry of RR Lyrae stars
P. Karczmarek, G. Pietrzyński, W. Gieren +6
We obtained single-phase near-infrared (NIR) magnitudes in the - and -band for a sample of 33 RR Lyrae stars in the Carina dSph galaxy. Applying different theoretical and emp…
The Araucaria Project. Accurate stellar parameters and distance to evolved eclipsing binary ASAS J180057-2333.8 in Sagittarius Arm
K. Suchomska, D. Graczyk, R. Smolec +11
We have analyzed the double-lined eclipsing binary system ASAS J180057-2333.8 from the All Sky Automated Survey (ASAS) catalogue . We measure absolute physical and orbital paramete…
The Araucaria Project: The First-Overtone Classical Cepheid in the Eclipsing System OGLE-LMC-CEP-2532
B. Pilecki, D. Graczyk, W. Gieren +10
We present here the first spectroscopic and photometric analysis of the double-lined eclipsing binary containing the classical, first-overtone Cepheid OGLE-LMC-CEP-2532 (MACHO 81.8…
