Description
Since the onset of exoplanet research, the field has been largely
dominated by the radial velocity and eclipse methods. However, thanks to a
steady progress in adaptive optics instruments and high-contrast imaging
methods, it is now starting to become possible to spatially resolve giant
planets from their parent stars, and thus study them with imaging and
spectroscopy. In this talk, I will present some recent results in this
field, including the coldest imaged companion to a Sun-like star, and
spatially resolved spectroscopy in the L'-band of an extrasolar planet.
The latter result implies non-equilibrium chemistry in the atmosphere of
the planet, and may hold clues to its history.
