The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. XIV. Classical and Type II Cepheids in the Galactic Bulge
I. Soszynski, A. Udalski, P. Pietrukowicz +7
The fourteenth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains Cepheid variables detected in the OGLE-II and OGLE-III fields toward the Galactic bulge. The catal…
First detection of period doubling in a BL Herculis type star. Observations and theoretical models
R. Smolec, I. Soszynski, P. Moskalik +9
We report on the discovery of the first BL Herculis star displaying period-doubling behaviour as predicted by the hydrodynamic models of Buchler & Moskalik. The star, with P=2.4d,…
Characterizing Lenses and Lensed Stars of High-Magnification Single-lens Gravitational Microlensing Events With Lenses Passing Over Source Stars
J. -Y. Choi, I. -G. Shin, S. -Y. Park +148
We present the analysis of the light curves of 9 high-magnification single-lens gravitational microlensing events with lenses passing over source stars, including OGLE-2004-BLG-254…
The Optical Gravitational Lensing Experiment. High Proper Motion Stars in the OGLE-III Data for Magellanic Clouds Fields
R. Poleski, I. Soszynski, A. Udalski +5
We present the results of a search for High Proper Motion (HPM) stars, i.e. the ones with μ> 100 mas/yr, in the direction to the Magellanic Clouds. This sky area was not examined i…
Discovery of period doubling in BL Herculis stars of the OGLE survey. Observations and theoretical models
R. Smolec, I. Soszynski, P. Moskalik +9
We report the discovery of a period doubling behaviour in a 2.4d BL Herculis-type variable of the Galactic bulge. Another bulge BL Her-type star (P=2.25d) is a strong period doubli…
The Araucaria Project. Accurate determination of the dynamical mass of the classical Cepheid in the eclipsing system OGLE-LMC-CEP-1812
G. Pietrzynski, I. Thompson, D. Graczyk. +8
We have analyzed the double-lined eclipsing binary system OGLE-LMC-CEP-1812 in the LMC and demonstrate that it contains a classical fundamental mode Cepheid pulsating with a period…
