Blue Large-Amplitude Pulsators and Other Short-Period Variable Stars in OGLE-IV Fields of the Outer Galactic Bulge

J. Borowicz, P. Pietrukowicz, J. Skowron +13

In this work, we search the OGLE-IV outer Galactic bulge fields for short-period variable objects. The investigation focuses on unexplored timescales roughly below one hour in an a…

KMT-2023-BLG-1866Lb: Microlensing super-Earth around an M dwarf host

Cheongho Han, Ian A. Bond, Andrzej Udalski +64

We investigate the nature of the short-term anomaly that appears in the lensing light curve of KMT-2023-BLG-1866. The anomaly was only partly covered due to its short duration, les…

OGLE-2018-BLG-0971, MOA-2023-BLG-065, and OGLE-2023-BLG-0136: Microlensing events with prominent orbital effects

Cheongho Han, Andrzej Udalski, Ian A. Bond +60

We undertake a project to reexamine microlensing data gathered from high-cadence surveys. The aim of the project is to reinvestigate lensing events with light curves exhibiting int…

Discovery of the Longest-Period Classical Cepheid in the Milky Way

I. Soszyński, D. M. Skowron, A. Udalski +12

We report the discovery of the classical Cepheid OGLE-GD-CEP-1884 (= GDS_J1535467-555656) with the longest pulsation period known in our Galaxy. The period of 78.14 d is nearly 10…

Virial Black Hole Masses for AGNs behind the Magellanic Clouds

Swayamtrupta Panda, Szymon Kozłowski, Mariusz Gromadzki +13

We use the spectroscopic data collected by the Magellanic Quasars Survey (MQS) as well as the photometric V- and I-band data from the Optical Gravitational Lensing Experiment (OGLE…

KMT-2023-BLG-0416, KMT-2023-BLG-1454, KMT-2023-BLG-1642: Microlensing planets identified from partially covered signals

Cheongho Han, Andrzej Udalski, Chung-Uk Lee +32

We investigate the 2023 season data from high-cadence microlensing surveys with the aim of detecting partially covered short-term signals and revealing their underlying astrophysic…

Candidates for Transiting Planets in OGLE-IV Galactic Bulge Fields

M. J. Mróz, P. Pietrukowicz, R. Poleski +13

We present results of a search for transiting exoplanets in 10-yr long photometry with thousands of epochs taken in the direction of the Galactic bulge. This photometry was collect…

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…
