Mass Segregation in Young LMC Clusters I. NGC 2157
Philippe Fischer, Carlton Pryor, Stephen Murray +2
We have carried out WFPC2 V- and I-band imaging of the young LMC cluster NGC 2157. Construction of a color-magnitude diagram and isochrone fitting yields an age of tau = 100 000 00…
Binaries in Globular Clusters
S. L. W. McMillan, C. Pryor, E. S. Phinney
Binary stars play a critical role in determining both the dynamical evolution and the observational appearance of globular star clusters. We present a summary of three talks presen…
The Optical Gravitational Lensing Experiment. The Catalog of Periodic Variable Stars in the Galactic Bulge. V. Periodic Variables in Fields: MM5-A, MM5-B, MM7-A and MM7-B
A. Udalski, A. Olech, M. Szymanski +5
We present the fifth part of the OGLE Catalog of Periodic Variable Stars in the Galactic bulge. 574 variable stars: 44 pulsating, 369 eclipsing and 161 miscellaneous type were dete…
The Kinematics of Dwarf Spheroidal Galaxies
Mario Mateo
I review observational data on the kinematic properties of dwarf spheroidal galaxies in the halo of the Milky Way and beyond. The present data confirm previous claims that these ga…
The Optical Gravitational Lensing Experiment. The General Catalog of Stars in the Galactic Bulge. I. The Stars in the Central Baade's Window OGLE Field BWC
M. Szymanski, A. Udalski, M. Kubiak +3
This paper presents the first part of the Optical Gravitational Lensing Experiment (OGLE) General Catalog of Stars in the Galactic bulge. The Catalog is based on observations colle…
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…
