KMT-2024-BLG-0404L: A triple microlensing system consisting of a star, a brown dwarf, and a planet
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +29
We have investigated the lensing event KMT-2024-BLG-0404. The light curve of the event exhibited a complex structure with multiple distinct features, including two prominent causti…
The 2016 super-Eddington outburst of SMC X-3: X-ray and optical properties and system parameters
L. J. Townsend, J. A. Kennea, M. J. Coe +4
On 2016 July 30 (MJD 57599), observations of the Small Magellanic Cloud by Swift/XRT found an increase in X-ray counts coming from a position consistent with the Be/X-ray binary pu…
Analysis of photometric uncertainties in the OGLE-IV Galactic Bulge microlensing survey data
J. Skowron, A. Udalski, S. Kozłowski +8
We present a statistical assessment of both, observed and reported, photometric uncertainties in the OGLE-IV Galactic bulge microlensing survey data. This dataset is widely used fo…
Ultra-Short-Period Binary Systems in the OGLE Fields Toward the Galactic Bulge
I. Soszynski, K. Stepien, B. Pilecki +11
We present a sample of 242 ultra-short-period (P < 0.22 d) eclipsing and ellipsoidal binary stars identified in the OGLE fields toward the Galactic bulge. Based on the light curve…
Distance to the SMC from eclipsing binaries
Dariusz Graczyk, Grzegorz Pietrzynski, Bogumił Pilecki +5
The preliminary distance to a long period eclipsing binary in the Small Magellanic Cloud SMC108.1.14904 is presented. The binary system contains two non-active G-type bright giants…
Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs
J. -Y. Choi, C. Han, A. Udalski +121
Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…
