The Subaru Seminar is
usually held in Room 104 of the Hilo Base Facility, adjacent
to the main lobby. Everyone is welcome to attend. If you are

" New optical tricks to find and study habitable Exoplanets "
Astronomers now understand that exoplanets are abundant, and most
stars may have planets. The most interesting exoplanets - the ones
that are potentially habitable - are unfortunately very challenging to
observe, and require optical systems that are radically different from
conventional imaging telescopes. Over the last decade, I have been
working with astronomers and optical physicists to develop and test
such systems for both ground-based and space-based telescopes. I will
describe how such systems work, and highlight a few major recent
advances I have been involved in. I will illustrate the strong synergy
between efforts in laboratories (mostly in support of future space
telescopes) and the Subaru Coronagraphic Extreme Adaptive Optics
(SCExAO) project on the Subaru telescope.
I will show that much progress has been accomplished in the last few
years, and that we can now foresee two short term strategies to image
and study other habitable worlds: (1) a medium-size (~2 to 4-m
diameter) space telescope equipped with a high performance coronagraph
can image Earth-like planets around nearby Sun-like stars; (2) an
extremely large telescope (ELT) can image habitable planets around
nearby low luminosity (M-type) stars.
Seminars are also held at JAC,
