Abstract

The Subaru Pathfinder Instrument for Detecting Exoplanets and Recovering Spectra (SPIDERS) has been built from the ground-up to demonstrate the fast-atmospheric self-coherent camera technique on-sky for the first time. This technique uses a common-path interferometer to measure and suppress speckles in real-time to build a dark hole, and to enable hyperspectral coherent differential imaging post-processing. These promise more than a hundred times improvement in sensitivity to young giant planets and debris disks around bright stars compared with previous, speckle-limited instruments. We will present SPIDERS, its laboratory performance on post-AO residuals, and an update on SPIDERS’ commissioning at Subaru.
