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…

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…

A Southern Sky and Galactic Plane Survey for Bright Kuiper Belt Objects

Scott Sheppard, Andrzej Udalski, Chad Trujillo +6

About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the firs…

Unbound or Distant Planetary Mass Population Detected by Gravitational Microlensing

T. Sumi, K. Kamiya, A. Udalski +36

Since 1995, more than 500 exoplanets have been detected using different techniques, of which 11 were detected with gravitational microlensing. Most of these are gravitationally bou…
