The LAOG-Planet Imaging Surveys

Abstract

With the development of high‐contrast imaging techniques and infrared detectors, vast efforts have been devoted during the past decade to detect and characterize lighter, cooler and closer companions to nearby stars, and ultimately image new planetary systems. Complementary to other observing techniques (radial velocity (RV), transit, micro‐lensing, pulsar‐timing), this approach has opened a new astrophysical window to study the physical properties and the formation mechanisms of brown dwarfs and planets. Here, I will briefly present the observing challenges, the different observing techniques, strategies and samples of current exoplanet imaging searches that have been selected in the context of the LAOG‐Planet Imaging Surveys. Finally, I will describe the most recent results that led to the discovery of giant planets that probably formed like those in our solar system, offering exciting and attractive perspectives for the future generation of deep imaging instruments.
