Abstract
The new 6-8 m class ground based telescopes equiped with very high-resolution adaptive optics have the potential to detect Jupiter-like planets around nearby stars. Direct detection will allow discoveries of planets, beyond the angular radius where Doppler spectroscopy achieves maximum sensitivity. In addition, direct imaging (and spectroscopy) will allow confirmation for those indirect detections which lie within 0.3–2 arcseconds in orbital radius. However, the technical requirements for direct imaging using high order adaptive optics are at the theoretical limits of performance and hence very challenging. Here we review the limiting performance of such systems. We give the exposure time required to detect such companions, and we point out the improvements required in order to accomplish exo-planets detection.
