The OGLE Collection of Variable Stars. Eclipsing Binaries in the Magellanic System
M. Pawlak, I. Soszyński, A. Udalski +10
We present the collection of eclipsing binaries in the Large and Small Magellanic Clouds, based on the OGLE survey. It contains 48605 systems, 40204 belonging to the LMC and 8401 t…
Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
The awakening of a classical nova from hibernation
P. Mroz, A. Udalski, P. Pietrukowicz +9
Cataclysmic variable stars (CVs) are close binary systems consisting of a white dwarf (primary) that is accreting matter from a low-mass companion star (secondary). From time to ti…
OGLE16aaa - a Signature of a Hungry Super Massive Black Hole
Łukasz Wyrzykowski, M. Zieliński, Z. Kostrzewa-Rutkowska +22
We present the discovery and first three months of follow-up observations of a currently on-going unusual transient detected by the OGLE-IV survey, located in the centre of a galax…
Multi-Mode and Non-Standard Classical Cepheids in the Magellanic System
I. Soszynski, A. Udalski, M. K. Szymanski +10
We present a sample of the most interesting classical Cepheids selected from the OGLE collection of classical Cepheids in the Magellanic System. The main selection criterion for th…
