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…

Four Microlensing Planets with Faint-source Stars Identified in the 2016 and 2017 Season Data

Cheongho Han, Andrzej Udalski, Doeon Kim +32

Microlensing planets occurring on faint source stars can escape detection due to their weak signals. Occasionally, detections of such planets are not reported due to the difficulty…

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…

The Cluster Ages Experiment (CASE). VIII. Age and Distance of the Globular Cluster 47 Tuc from the Analysis of Two Detached Eclipsing Binaries

I. B. Thompson, A. Udalski, A. Dotter +20

We use photometric and spectroscopic observations of the eclipsing binary E32 in the globular cluster 47 Tuc to derive the masses, radii, and luminosities of the component stars. T…
