| Abstract: |
Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 ìm. Best results have been obtained on OGLE-TR-113b using the SOFI near-infrared camera on ESO’s New Technology Telescope. Its K-band transit shows a remarkably flat bottom indicating low stellar limb darkening. Secondary eclipse photometry has resulted in a formal 3μ detection, but residual systematic effects make this detection rather uncertain. |
