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,…
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 Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. XIII. Long-Period Variables in the Small Magellanic Cloud
I. Soszynski, A. Udalski, M. K. Szymanski +7
The thirteenth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains 19384 long-period variables (LPVs) detected in the Small Magellanic Cloud. The sample is composed…
Microlensing Binaries Discovered through High-Magnification Channel
I. -G. Shin, J. -Y. Choi, S. -Y. Park +148
Microlensing can provide a useful tool to probe binary distributions down to low-mass limits of binary companions. In this paper, we analyze the light curves of 8 binary lensing ev…
