Over 24 000 Delta Scuti Stars in the Galactic Bulge and Disk from the OGLE Survey
I. Soszyński, P. Pietrukowicz, J. Skowron +11
We present the largest collection of delta Scuti-type stars in the Milky Way. Together with the recently published OGLE collection of delta Sct variables in the inner Galactic bulg…
Single-lens mass measurement in the high-magnification microlensing event Gaia19bld located in the Galactic disc
K. A. Rybicki, Ł. Wyrzykowski, E. Bachelet +66
We present the photometric analysis of Gaia19bld, a high-magnification () microlensing event located in the southern Galactic plane, which exhibited finite source and m…
Lens parameters for Gaia18cbf -- a long gravitational microlensing event in the Galactic plane
Katarzyna Kruszyńska, Ł. Wyrzykowski, K. A. Rybicki +29
Context: The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive lenses, including black h…
The 2019 outburst of the 2005 classical nova V1047 Cen: a record breaking dwarf nova outburst or a new phenomenon?
E. Aydi, K. V. Sokolovsky, J. S. Bright +28
We present a detailed study of the 2019 outburst of the cataclysmic variable V1047~Cen, which hosted a classical nova eruption in 2005. The peculiar outburst occurred 14 years afte…
Wide-orbit exoplanets are common. Analysis of nearly 20 years of OGLE microlensing survey data
R. Poleski, J. Skowron, P. Mróz +8
We use nearly 20 years of photometry obtained by the OGLE survey to measure the occurrence rate of wide-orbit (or ice giant) microlensing planets, i.e., with separations from ~5 AU…
Time-series and Phasecurve Photometry of Episodically-Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200 and ZTF
Josiah N. Purdum, Zhong-Yi Lin, Bryce T. Bolin +49
We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outburs…
