The OGLE Collection of Variable Stars. Over 15 000 Delta Scuti Stars in the Large Magellanic Cloud
I. Soszyński, P. Pietrukowicz, A. Udalski +12
We present the OGLE collection of delta Scuti stars in the Large Magellanic Cloud and in its foreground. Our dataset encompasses a total of 15 256 objects, constituting the largest…
Blue Large-Amplitude Pulsators and Other Short-Period Variable Stars in the OGLE-IV Galactic Disk Fields
J. Borowicz, P. Pietrukowicz, P. Mróz +12
Blue Large-Amplitude Pulsators (BLAPs) form a mysterious class of variable stars with typical periods of tens of minutes and amplitudes above 0.1 mag. In this work, we present resu…
Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020
Tianshu Wang, Wei Zhu, Shude Mao +83
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
Blazhko-type modulation in the double-mode RR Lyrae stars of the OGLE Galactic bulge collection
R. Smolec, I. Soszyński, A. Udalski +10
We present the analysis of Blazhko-type modulation in double-mode RR Lyrae (RRd) stars found in the OGLE photometry of the Galactic bulge. Modulation is detected in 15 stars. Most…
OGLE-BLG182.1.162852: An Eclipsing Binary with a Circumstellar Disk
N. J. Rattenbury, Ł. Wyrzykowski, Z. Kostrzewa-Rutkowska +11
We present the discovery of a plausible disk-eclipse system OGLE-BLG182.1.162852. The OGLE light curve for OGLE-BLG182.1.162852 shows three episodes of dimming by …
