Uncovering galactic and extragalactic planets by gravitational microlensing
M. Dominik
With its planet detection efficiency reaching a maximum for orbital radii between 1 and 10 AU, microlensing provides a unique sensitivity to planetary systems similar to our own ar…

Determining the abundance of extragalactic planets
M. Dominik
Gravitational microlensing provides a unique technique to reveal information about extragalactic planets. A network of at least four 2m-class telescopes distributed around the nort…
