No Evidence for Classical Cepheids and a New Dwarf Galaxy Behind the Galactic Disk
P. Pietrukowicz, A. Udalski, M. K. Szymanski +9
Based on data from the ongoing OGLE Galaxy Variability Survey (OGLE GVS) we have verified observed properties of stars detected by the near-infrared VVV survey in a direction near…
The OGLE Collection of Variable Stars. Anomalous Cepheids in the Magellanic Clouds
I. Soszynski, A. Udalski, M. K. Szymanski +10
We present a collection of 250 anomalous Cepheids (ACs) discovered in the OGLE-IV fields toward the Large (LMC) and Small Magellanic Cloud (SMC). The LMC sample is an extension of…
Planet Sensitivity from Combined Ground- and Space-based Microlensing Observations
Wei Zhu, Andrew Gould, Charles Beichman +45
To move one step forward toward a Galactic distribution of planets, we present the first planet sensitivity analysis for microlensing events with simultaneous observations from spa…
A high-velocity bulge RR Lyrae variable on a halo-like orbit
Andrea Kunder, R. Michael Rich, Keith Hawkins +21
We report on the RR Lyrae variable star, MACHO 176.18833.411, located toward the Galactic bulge and observed within the data from the ongoing Bulge RR Lyrae Radial Velocity Assay (…
OGLE Atlas of Classical Novae I. Galactic Bulge Objects
P. Mroz, A. Udalski, R. Poleski +8
Eruptions of classical novae are possible sources of lithium formation and gamma-ray emission. Nova remnants can also become Type Ia supernovae (SNe Ia). The contribution of novae…
Ultra-Short-Period Binary Systems in the OGLE Fields Toward the Galactic Bulge
I. Soszynski, K. Stepien, B. Pilecki +11
We present a sample of 242 ultra-short-period (P < 0.22 d) eclipsing and ellipsoidal binary stars identified in the OGLE fields toward the Galactic bulge. Based on the light curve…
