Journal ArticleDOI
No large population of unbound or wide-orbit Jupiter-mass planets
Przemek Mróz,Andrzej Udalski,Jan Skowron,Radosław Poleski,Radosław Poleski,Szymon Kozłowski,Michał K. Szymański,Igor Soszyński,Łukasz Wyrzykowski,Paweł Pietrukowicz,Krzysztof Ulaczyk,Krzysztof Ulaczyk,D. M. Skowron,Michał Pawlak +13 more
TL;DR: A sample of microlensing events six times larger than that of ref. 11 is analysed, finding no excess of events with timescales in this range, with a 95 per cent upper limit on the frequency of Jupiter-mass free-floating or wide-orbit planets of 0.25 planets per main-sequence star.
Journal ArticleDOI
A three-dimensional map of the Milky Way using classical Cepheid variable stars
D. M. Skowron,Jan Skowron,Przemek Mróz,Andrzej Udalski,Paweł Pietrukowicz,Igor Soszyński,Michał K. Szymański,Radosław Poleski,Radosław Poleski,Szymon Kozłowski,Krzysztof Ulaczyk,Krzysztof Ulaczyk,Krzysztof A. Rybicki,Patryk Iwanek +13 more
TL;DR: In this paper, the authors constructed a 3D map of the Milky Way in three dimensions, based on the positions and distances of thousands of classical Cepheids variable stars.
Journal ArticleDOI

TL;DR: In this paper, the first space-based microlens parallax measurement of an isolated star is presented, based on the striking differences in the lightcurve as seen from Earth and from Spitzer (~ 1 AU to the west).
Journal ArticleDOI
