Polish-born astrophysicist Bohdan Paczyński
(b. 1940), at Princeton University
since 1982, is known for his theoretical work on gamma ray bursters---he was an early proponent of their being at cosmological distances---and for leading searches for gravitational lensing by low-mass stars and substellar objects

Gravitational microlensing
Gravitational microlensing is an astronomical phenomenon due to the gravitational lens effect. It can be used to detect objects ranging from the mass of a planet to the mass of a star, regardless of the light they emit. Typically, astronomers can only detect bright objects that emit lots of light ...
