Abstract
The detection of exoplanets via gravitational microlensing is closely related to the transit detection method in that both approaches require regular, very precise photometry of many stars over periods of years. Microlensing though, produces a brief apparent one-off increase in the star’s brightness and the physical mechanism involved is quite different from that for a transit.
