Abstract:
Over the last decade, we have seen an exponential growth of the exoplanet imaging field. I will first give a (strongly bias) overview of the first decade of direct imaging, where clever observing strategies and advance post-processing algorithms were in- vented, and how these were used to perform the first large scale near-infrared imaging campaigns, the GDPS, the Keck survey, and the IDPS campaigns. Together, more than 300 young nearby stars were surveyed using more than a thousand hours of 8 - 10m time. A statistical analysis of the data shows that giant planets are rare >20 au around stars, but they do exist, following the IDPS discovery, in 2008, of the HR 8799 four planet system.
Over the past few years, the first generation of facility-class extreme adaptive optics systems became operational, such as the Gemini Planet Imager, that are delivering a contrast 100x better than previous generation instruments. Now half way through its 600 stars campaign, I will briefly review some of the science highlights that have been accomplished so far. I will finally pre- sent what we can expect in the next decade, including what we can expect from 30m class telescopes.
