| Abstract: |
We present results of an exploratory study to use near-infrared integral field spectroscopy
to observe extrasolar planets. Our concept was tested with a K-Band
time series observations of HD209458b and HD189733b obtained with
SINFONI at the VLT and OSIRIS at Keck during secondary transits at a
spectral resolution of R=3000. In this article we focus on the
specific problems of ground-based, high signal-to-noise observations
and demonstrate possible solutions for spetral timeseries. An
advanced reduction method using elements of a spectral-differential
decorrelation is discussed. |
