The Araucaria Project. The Distance to the Sculptor Group Galaxy NGC 55 from a Newly Discovered Abundant Cepheid Population
G. Pietrzynski, W. Gieren, I. Soszynski +10
We have detected, for the first time, Cepheid variables in the Sculptor Group SB(s)m galaxy NGC 55. From wide-field images obtained in the optical V and I bands during 77 nights in…
The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry
Frederic Pont, Claire Moutou, Michael Gillon +14
Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. He…
OGLE 2004-BLG-254: a K3 III Galactic Bulge Giant spatially resolved by a single microlens
A. Cassan, J. -P. Beaulieu, P. Fouque +37
We present an analysis of OGLE 2004-BLG-254, a high-magnification and relatively short duration microlensing event in which the source star, a Bulge K3-giant, has been spatially re…
The Optical Gravitational Lensing Experiment. Variable Baseline Microlensing Events in the Galactic Bulge
L. Wyrzykowski, A. Udalski, S. Mao +5
We present the first systematic search for microlensing events with variability in their baselines using data from the third phase of the Optical Gravitational Lensing Experiment (…
The Araucaria Project. An Accurate Distance to the Local Group Galaxy NGC 6822 from Near-Infrared Photometry of Cepheid Variables
W. Gieren, G. Pietrzynski, K. Nalewajko +5
We have measured near-infrared magnitudes in the J and K bands for 56 Cepheid variables in the Local Group galaxy NGC 6822 with well-determined periods and optical light curves in…
The Araucaria Project. A Wide-Field Photometric Survey for Cepheid Variables in NGC 3109
G. Pietrzynski, W. Gieren, A. Udalski +5
We have obtained mosaic images of NGC 3109 in the V and I bands on 74 nights, spanning approximately one year. From these data, we have conducted an extensive search for Cepheid va…
