The phase cycle brightness method for detecting exoplanets involves observing the changes in brightness of a star as an orbiting planet reflects more or less light at different points in its orbit, similar to how the brightness of the Moon changes during its lunar cycle due to the varying amounts of sunlight it reflects as seen from Earth.
