OGLE-GAL-ACEP-091 -- The First Known Multi-Mode Anomalous Cepheid
I. Soszyński, R. Smolec, A. Udalski +12
Anomalous Cepheids (ACs) are metal-deficient, core-helium-burning pulsating stars with masses in the range 1.2-2.2 M_S. Until recently, all known ACs were pure single-mode pulsator…
Additional Galactic Cepheids from the OGLE Survey
I. Soszyński, A. Udalski, M. K. Szymański +11
We report on the results of a comprehensive search for Cepheid variable stars in the fields photometricallymonitored by the OGLE Galaxy Variability Survey. We identify 742 Cepheids…
Properties of the Milky Way's Old Populations Based on Photometric Metallicities of the OGLE RR Lyrae Stars
P. Pietrukowicz, A. Udalski, I. Soszynski +11
We have used photometric data on almost 91 000 fundamental-mode RR Lyrae stars (type RRab) detected by the OGLE survey to investigate properties of old populations in the Milky Way…
OGLE-ing the Magellanic System: Optical Reddening Maps of the Large and Small Magellanic Cloud from Red Clump Stars
D. M. Skowron, J. Skowron, A. Udalski +12
We present the most extensive and detailed reddening maps of the Magellanic Clouds (MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on the dee…
Over 78 000 RR Lyrae Stars in the Galactic Bulge and Disk from the OGLE Survey
I. Soszyński, A. Udalski, M. Wrona +11
We present an upgrade of the OGLE Collection of RR Lyrae stars in the Galactic bulge and disk. The size of our sample has been doubled and reached 78 350 RR Lyr variables, of which…
Mapping the Northern Galactic Disk Warp with Classical Cepheids
D. M. Skowron, J. Skowron, P. Mróz +11
We present an updated three dimensional map of the Milky Way based on a sample of 2431 classical Cepheid variable stars, supplemented with about 200 newly detected classical Cephei…
