" 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.
