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…
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…
Parallax of OGLE-2018-BLG-0596: A Low-mass-ratio Planet around an M-dwarf
Youn Kil Jung, Andrew Gould, Andrzej Udalski +63
We report the discovery of a microlensing planet OGLE-2018-BLG-0596Lb, with preferred planet-host mass ratio . The planetary signal, which is chara…
spotted stars toward the OGLE Galactic bulge fields
P. Iwanek, I. Soszyński, J. Skowron +12
We present the discovery and statistical analysis of spotted variable stars toward and inside the Galactic bulge from over two-decade-long Optical Gravitational Lensing E…
Discovery and Follow-up of the Unusual Nuclear Transient OGLE17aaj
M. Gromadzki, A. Hamanowicz, L. Wyrzykowski +31
We report on the discovery and follow-up of a peculiar transient, OGLE17aaj, which occurred in the nucleus of a weakly active galaxy. We investigate whether it can be interpreted a…
