The Optical Gravitational Lensing Experiment. Optical Monitoring of the Gravitationally Lensed Quasar HE1104-1805 in 1997-2002
L. Wyrzykowski, A. Udalski, P. L. Schechter +6
We present results of the long term monitoring of the gravitationally lensed quasar HE1104-1805. The photometric data were collected between August 1997 and January 2002 as a subpr…
Beta Cephei and SPB stars in the Large Magellanic Cloud
Z. Kolaczkowski, A. Pigulski, I. Soszynski +8
This is a progress report of the study of pulsating main-sequence stars in the LMC. Using the OGLE-II photometry supplemented by the MACHO photometry, we find 64 Beta Cephei stars…
OGLE-2003-BLG-262: Finite-Source Effects from a Point-Mass Lens
Jaiyul Yoo, D. L. DePoy, A. Gal-Yam +16
We analyze OGLE-2003-BLG-262, a relatively short, t_E=12.5+-0.1day, microlensing event generated by a point-mass lens transiting the face of a K giant source in the Galactic bulge.…
The Optical Gravitational Lensing Experiment. Catalog of RR Lyrae Stars in the Large Magellanic Cloud
I. Soszynski, A. Udalski, M. Szymanski +6
We present the catalog of RR Lyrae stars discovered in a 4.5 square degrees area in the central parts of the Large Magellanic Cloud (LMC). Presented sample contains 7612 objects, i…
The Optical Gravitational Lensing Experiment. Additional Planetary and Low-Luminosity Object Transits from the OGLE 2001 and 2002 Observational Campaigns
A. Udalski, G. Pietrzynski, M. Szymanski +5
The photometric data collected by OGLE-III during the 2001 and 2002 observational campaigns aiming at detection of planetary or low-luminosity object transits were corrected for sm…
The Optical Gravitational Lensing Experiment. Catalog of stellar proper motions in the OGLE-II Galactic bulge fields
T. Sumi, X. Wu, A. Udalski +8
We present a proper motion (μ) catalogue of 5,080,236 stars in 49 Optical Gravitational Lensing Experiment II (OGLE-II) Galactic bulge (GB) fields, covering a range of -11 deg. <l<…
The Optical Gravitational Lensing Experiment. Eclipsing Binary Stars in the Large Magellanic Cloud
L. Wyrzykowski, A. Udalski, M. Kubiak +6
We present the catalog of 2580 eclipsing binary stars detected in 4.6 square degree area of the central parts of the Large Magellanic Cloud. The photometric data were collected dur…
The Optical Gravitational Lensing Experiment. Planetary and Low-Luminosity Object Transits in the Carina Fields of the Galactic Disk
A. Udalski, O. Szewczyk, K. Zebrun +5
We present results of the second planetary and low-luminosity object transit campaign conducted by the OGLE-III survey. Three fields (35'x35' each) located in the Carina regions of…
The Optical Gravitational Lensing Experiment. Catalog of RR Lyrae Stars from the Small Magellanic Cloud
I. Soszynski, A. Udalski, M. Szymanski +6
We present the catalog of RR Lyrae stars from 2.4 square degrees of central parts of the Small Magellanic Cloud (SMC). The photometric data were collected during four years of the…
