Confirming transiting exoplanets with the Fraunhofer Telescope Wendelstein

In the Bavarian Alps, an optimal exoplanet follow-up device is located. Besides a 43cm telescope for long term photometric observations, the observatory operates the 2.1m Fraunhofer Telescope Wendelstein, which is equipped with the highly temperature- and pressure-stabilized, frequency comb calibrated Echelle spectrograph MaHPS (R ∼ 65000) to conduct radial velocity measurements. Further, the 3KK instrument is able to conduct multiband photometry with its two Apogee-ALTA F3041 cameras for optical and its H2RG CMOS for NIR light, discerning different transit scenarios, since the characteristics of limb darkening cause differing eclipse depths and shapes, depending on the nature of the system. The combination of the photometric and spectroscopic observations allow for confident confirmation or discarding of exoplanetary candidates.
