Historic microlensing events in the euclid Galactic Bulge Survey
V. Bozza, L. Salmeri, P. Rota +47
Microlensing campaigns have a long history of observations covering the Galactic bulge, where thousands of detections have been obtained, including many exoplanetary systems. The E…
OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host
M. J. Mróz, R. Poleski, A. Udalski +70
We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…
Dark lens candidates from Gaia Data Release 3
K. Kruszyńska, Ł. Wyrzykowski, K. A. Rybicki +48
Gravitational microlensing is a phenomenon that allows us to observe dark remnants of stellar evolution even if they no longer emit electromagnetic radiation. In particular, it can…
OGLE-2019-BLG-0362Lb: A super-Jovian-mass planet around a low-mass star
Sun-Ju Chung, Jennifer C. Yee, Andrej Udalski +28
We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a short-duration anomaly near the peak of the light curve, which is caused…
Frequency analysis of Delta Scuti stars towards the Galactic bulge
H. Netzel, P. Pietrukowicz, I. Soszyński +1
We have performed a frequency analysis of 10,092 Delta Scuti-type stars detected in the fourth phase of the Optical Gravitational Lensing Experiment (OGLE) towards the Galactic bul…
OGLE-2017-BLG-1434Lb: Eighth q < 1 * 10^-4 Mass-Ratio Microlens Planet Confirms Turnover in Planet Mass-Ratio Function
A. Udalski, Y. -H. Ryu, S. Sajadian +55
We report the discovery of a cold Super-Earth planet (m_p=4.4 +/- 0.5 M_Earth) orbiting a low-mass (M=0.23 +/- 0.03 M_Sun) M dwarf at projected separation a_perp = 1.18 +/- 0.10 AU…
OGLE Collection of Star Clusters. New Objects in the Magellanic Bridge and the Outskirts of the Small Magellanic Cloud
M. Sitek, M. K. Szymański, A. Udalski +13
The Magellanic System (MS) encompasses the nearest neighbors of the Milky Way, the Large (LMC) and Small (SMC) Magellanic Clouds, and the Magellanic Bridge (MBR). This system conta…
VISTA Variables in the Vía Láctea (VVV): Halfway Status and Results
Maren Hempel, Dante Minniti, István Dékány +89
The VISTA Variables in the Vía Láctea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has a…
Large Magellanic Cloud Cepheids in the ASAS data
P. Karczmarek, W. A. Dziembowski, P. Lenz +2
A catalog of Cepheids in the Large Magellanic Cloud (LMC) from the ASAS project is presented. It contains data on 65 fundamental mode pulsators with periods longer than about 8 day…
Dwarf Nova V1040 Centauri and Variable Stars in its Vicinity
A. Rutkowski, P. Pietrukowicz, A. Olech +5
We present the results of a photometric campaign of the dwarf nova V1040 Cen. The light curve shows two normal outbursts with recurrence time ~ 40 days and amplitude ~ 2.5 mag. Qui…
