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…
