The discovery of OGLE 2005-BLG-390Lb, the first cool rocky/i cy exoplanet, impressively demonstrated the sensitivity of the microlensing technique to extra-solar planets below 10 M�. A planet of 1 Minstead of the expected 5 Mfor OGLE 2005-BLG-390Lb (with an uncertainty factor of two) in the same spot would have provided a detectable deviation with an amplitude of � 3 per cent and a duration of � 12 h. While a standard sampling interval of 1.5 to 2.5 hours for microlensing follow-up observations… Expand

Realisation of a fully-deterministic microlensing observing strategy for inferring planet populations
Within less than 15 years, the count of known planets orbiting stars other than the Sun has risen from none to more than 400 with detections arising from four successfully applied techniques:Expand
Extrasolar planet detections with gravitational microlensing
Abstract Microlensing light curves due to single stars are symmetric and typically last for a month. So far about 4000 microlensing events have been discovered in real-time, the vast majority towardExpand

OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
Discussing the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale t_E ∼ 300 d, we present a methodology for identifying the nature of localised deviations fromExpand
The first extrasolar planet detected via gravitational microlensing
Abstract In gravitational microlensing, distant planetary systems may be discovered by utilizing them as naturally occuring lenses. Efforts to find planets by this technique began in the 1990s. TheExpand
