-
This so-called microlensing will occur either before or after the main lensing event, depending on whether the planet leads or trails its parent star.
-
The planet was detected using a technique called microlensing, in which one star passes in front of another as seen from Earth.
-
Well, I don't think it necessarily has to be "microlensing" but anything that modifies the light on its path.

The detection techniques such as transit and gravitational microlensing will provide the basic details of the alien planets.
orbitalcombustion commented on the word microlensing
Gravitational microlensing: when a blackhole moves in front of a celestial body thus disturbing its apparent magnitude from our frame of reference (e.g. (exempli gratia) if a Terr rotating blackhole moved in front of Sirius we would be able to detect it because its magnitude and position would be altered by the flux in space-time created about the event horizon). Can be detected easiest with x-ray telescopes since singularities theoretically crush matter and convert the energy source into x-rays which radiate towards Earth.
