Igor Soszyński,Radosław Smolec,Andrzej Udalski,Michał K. Szymański,Paweł Pietrukowicz,D. M. Skowron,Jan Skowron,Przemek Mróz,Radosław Poleski,S. Kozłowski,Patryk Iwanek,Marcin Wrona,Mariusz Gromadzki,Krzysztof Ulaczyk,Krzysztof A. Rybicki +14 more
TL;DR: The first candidate for an anomalous Cepheid pulsating in more than one radial mode - OGLE-GAL-ACEP-091 - was recently identified in the Milky Way based on the photometric database of the Optical Gravitational Lensing Experiment (OGLE) survey as mentioned in this paper.
Journal ArticleDOI
Infrared Spectroscopy of the Recent Outburst in V1047 Cen (Nova Centauri 2005)
T. R. Geballe,Dipankar P. K. Banerjee,A. Evans,Robert D. Gehrz,Charles E. Woodward,Przemek Mróz,Andrzej Udalski,Ulisse Munari,Sumner Starrfield,K. L. Page,Kirill Sokolovsky,Kirill Sokolovsky,Franz-Josef Hambsch,Gordon Myers,Elias Aydi,David A. H. Buckley,F. M. Walter,R. M. Wagner +17 more
TL;DR: In this article, the authors present near-infrared spectroscopy to show that the present outburst is most likely a dwarf nova (DN) eruption, and discuss the possible reasons for its early occurrence.

TL;DR: In this article, the authors conducted a project of reinvestigating the 2017-2019 microlensing data collected by the high-cadence surveys with the aim of finding planets that were missed due to the deviations of planetary signals from the typical form of short-term anomalies.

TL;DR: In this article, a microlensing event with an obvious but incompletely resolved brief anomaly feature around the peak of the light curve is analyzed, where the origin of the anomaly is identified to be a companion to the lens with a low mass ratio.
Journal ArticleDOI
New Self-lensing Models of the Small Magellanic Cloud: Can Gravitational Microlensing Detect Extragalactic Exoplanets?
Przemek Mróz,Radosław Poleski +1 more
TL;DR: In this article, the authors used three-dimensional distributions of classical Cepheids and RR~Lyrae stars in the Small Magellanic Cloud (SMC) to model the stellar density distribution of a young and old stellar population in that galaxy.
