" Directly Imaging and Characterizing Young Planetary Systems with the Subaru Telescope "

Thayne Currie (NAOJ/Subaru)

In this talk, I will discuss recent results from collaborators and I using the Subaru Telescope to directly image and characterize young extrasolar planets and planet-forming disks, primarily with the Subaru Coronagraphic Extreme Adaptive Optics project. I will summarize the architecture of SCExAO (wavefront control, coronagraphy) and science instruments currently in use and planned for use in the near future. SCExAO's first science results reveal high contrast imaging capabilities roughly comparable to that from the Gemini Planet Imager at first light, newly resolved debris disks, simultaneous JHK spectra of benchmark planetary companions, and new candidate companions. Additionally, I will discuss detailed atmospheric characterization of moderate-contrast, wide-separation exoplanets with AO188, a forerunner of the science we plan to do with SCExAO in the near future. I will close by discussing the instrumentation and scientific trajectory of SCExAO, how it will mature technologies necessary to imaging planets in reflected light, including with the Thirty Meter Telescope, and plans to conduct an Intensive Proposal focused on exoplanet discovery and characterization that exceeds current rival programs using GPI and SPHERE.

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