KMTNet

The Korea Microlensing Telescope Network is an ongoing wide-field photometric system that aims to discover extrasolar planets using gravitational microlensing. The system leverages three identical 1.6 m wide-field optical telescopes located at the Cerro Tololo [Inter-American Observatory|Cerro-Tololo Inter-American Observatory] in Chile, the South [African Astronomical Observatory] in South Africa, and the Siding Spring Observatory in Australia. All three telescopes share a latitude of −30 degrees enabling continuous monitoring of the galactic bulge during 8 months of each year and other targets in the south hemisphere during non-bulge season such as near-earth asteroids and supernovae. Currently, 232 microlensing planets have been described by KMTNet. The KMNet survey was recently used to show that super-earths are common in Jupiter-like orbits.
