Two new free-floating or wide-orbit planets from microlensing
P. Mroz, A. Udalski, D. P. Bennett +57
Planet formation theories predict the existence of free-floating planets that have been ejected from their parent systems. Although they emit little or no light, they can be detect…
OGLE Collection of Galactic Cepheids
A. Udalski, I. Soszyński, P. Pietrukowicz +10
We present here a new major part of the OGLE Collection of Variable Stars - OGLE Collection of Galactic Cepheids. The new dataset was extracted from the Galaxy Variability Survey i…
OGLE-2017-BLG-0039: Microlensing Event with Light from the Lens Identified from Mass Measurement
C. Han, Y. K. Jung, A. Udalski +58
We present the analysis of the caustic-crossing binary microlensing event OGLE-2017-BLG-0039. Thanks to the very long duration of the event, with an event time scale $t_{\rm E}\sim…
OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
M. Dominik, E. Bachelet, V. Bozza +40
(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…
Rotational variation of the linear polarisation of the asteroid (3200) Phaethon as evidence for inhomogeneity in its surface properties
G. Borisov, M. Devogèle, A. Cellino +23
Asteroid (3200) Phaethon is a Near-Earth Apollo asteroid with an unusual orbit that brings it closer to the Sun than any other known asteroid. Its last close approach to the Earth…
A telescope control and scheduling system for the Gravitational-wave Optical Transient Observer (GOTO)
Martin Dyer, Vik Dhillon, Stuart Littlefair +5
The Gravitational-wave Optical Transient Observer (GOTO) is a wide-field telescope project aimed at detecting optical counterparts to gravitational wave sources. The prototype inst…
