" High Contrast Imaging with Adaptive Optics and Integral Field Spectroscopy "

Michael McElwain (Princeton University)

While more than 200 extrasolar planets have been discovered using indirect techniques, the direct detection of this class of object has remained at the sensitivity limits of ground based observatories. The development of improved adaptive optics systems and high contrast instruments has increased the sensitivity to extrasolar planets, and over the next 5 years, instruments will be capable of detecting Jupiter-mass planets around nearby stars. I will present the recent results from the high contrast observations using the Keck II AO system and OSIRIS integral field spectrograph (IFS). The OSIRIS integral field data is used to simultaneously monitor the PSF over a broad band (20% filter), and post-processing of this data product can be used to suppress the optical speckles that currently limit the sensitivity to faint companions. Finally, I will discuss the design of an IFS to observe in parallel with the Subaru SEEDS survey.

Seminars are also held at JAC, CFHT, and IfA.
