The Optical Gravitational Lensing Experiment. Follow-Up Observations of the Macho Microlensing Event in the Galactic Bulge
M. Szymanski, A. Udalski, J. Kaluzny +3
We present follow-up observations of a gravitational microlensing candidate found by the MACHO collaboration in the Galactic bulge. The photometric data cover a period near the max…
The Optical Gravitational Lensing Experiment. Variable stars in the Sculptor dwarf speroidal galaxy
J. Kaluzny, M. Kubiak, M. Szymanski +3
The central area of the Sculptor dwarf galaxy was surveyed for variable stars as a side-program of the OGLE project. Light curves in the V band were obtained for 226 RR Lyr stars a…
Open clusters as tracers of the evolution of the Galaxy
Janusz Kaluzny, Wojtek Krzeminski, Beata Mazur
Deep color-magnitude diagrams are presented for poorly known open clusters Cr 261, Be 18, Be 54, Tr 5 and BH176. All clusters are old objects with age\geq 4 Gyr. BH176 is either ol…
Results from the Optical Gravitational Lensing Experiment (OGLE)
B. Paczynski, K. Z. Stanek, A. Udalski +6
The analysis of the first three years of the OGLE data revealed 12 microlensing events of the Galactic bulge stars, with the characteristic time scales in the range $ 8.6 < t_0 < 8…
Evidence for the Galactic Bar from the Two Color Photometry of the Bulge Red Clump Stars
K. Z. Stanek, M. Mateo, A. Udalski +4
The Optical Gravitational Lensing Experiment (OGLE, Udalski et al.~1994a; Paczyński et al.~1994b -- these proceedings; and references therein) is an extensive photometric search fo…
The Optical Gravitational Lensing Experiment. Deep Photometry of the Sagittarius Dwarf Spheroidal Galaxy
Mario Mateo, A. Udalski, M. Szymanski +3
We present deep CCD photometry of a field in the newly discovered dwarf spheroidal galaxy in Sagittarius (hereafter Sgr), and of a nearby control field. These data (totaling ~3.5 h…
