Incorporating physical source parameters into microlensing modeling

Mateusz J. Mróz, Radosław Poleski, Andrzej Udalski +14

Modeling of complex microlensing events suffers from many difficult-to-disentangle degeneracies. This is especially the case for orbital motion of the source in a binary system, th…

Thirty Circumbinary Disk Occultation Systems (KH 15D-like stars) from the OGLE Project

M. A. Urbanowicz, I. Soszyński, P. Pietrukowicz +14

We present a catalog of 30 stars that are candidates for KH 15D-like binary systems, in which the observed brightness variations are caused by a circumbinary dusty disk that period…

Searching for outbursts from Symbiotic Binaries in GOTO and ATLAS data

G. Ramsay, K. Ackley, S. Belkin +46

Symbiotic Binaries contain a white dwarf accreting material from a red giant star through a wind. We present the results of a search for outbursts from Symbiotic Binaries using pho…

Six binary brown dwarf candidates identified by microlensing

Cheongho Han, Chung-Uk Lee, Ian A. Bond +57

In this study, we analyze microlensing events from the 2023 and 2024 observing seasons to identify cases likely caused by binary systems composed of BDs. By applying criteria that…

Doubling the Number of Blue Large-Amplitude Pulsators: Final Results of Searches for BLAPs in the OGLE Inner Galactic Bulge Fields

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

Blue Large-Amplitude Pulsators (BLAPs) are rare short-period (80 min) pulsating variable stars exhibiting large-amplitude brightness variations (typically between 0.1 and…

Three binary-source binary-lens microlensing events from the 2024 microlensing campaign

Cheongho Han, Chung-Uk Lee, Andrzej Udalski +27

We investigated microlensing events detected by the OGLE and KMTNet surveys during the 2024 observing season, focusing on those that exhibit very complex anomaly features. Through…
