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-2018-BLG-1269Lb: A Jovian Planet With A Bright, Host
Youn Kil Jung, Andrew Gould, Andrzej Udalski +54
We report the discovery of a planet in the microlensing event OGLE-2018-BLG-1269, with planet-host mass ratio , i.e., times smaller than the Jupiter/Su…
Microlensing optical depth and event rate in the OGLE-IV Galactic plane fields
Przemek Mroz, Andrzej Udalski, Michal K. Szymanski +10
Searches for gravitational microlensing events are traditionally concentrated on the central regions of the Galactic bulge but many microlensing events are expected to occur in the…
Ogle-2018-blg-0677lb: A super earth near the galactic bulge
Antonio Herrera-Martín, M. D. Albrow, A. Udalski +30
We report the analysis of the microlensing event OGLE-2018-BLG-0677. A small feature in the light curve of the event leads to the discovery that the lens is a star-planet system. A…
