Currently known planetary and brown dwarf companions to low-mass (0.07−0.3 M_⊙) stars; data from http://exoplanet.eu/ on 2018 Jun 20. Symbol colour shows the discovery method: black for imaging, red for transit, blue for radial velocity, and green for microlensing. The symbol size increases for lower V-band magnitudes; open symbols lack a V-band magnitude. The grey wedges show the region planets close to the Einstein radius causing resonant microlensing distortions (see Eq. (10)). The transparency of the wedges increases as the closest approach increases.
