OGLE-2018-BLG-0799Lb: a Planet with Spitzer Parallax
Weicheng Zang, Yossi Shvartzvald, Andrzej Udalski +73
We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based telescopes, and the planet-…
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…
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…
