First z-band albedo of an exoplanet

Using WiFSIP at STELLA-I, the first-ever measurement of the albedo of an exoplanet using z-band photometry was obtained: Combining 11 eclipse z-band light curves of the hot Jupiter HAT-P-32b, the photometric precision could be pushed to 0.1 milli-mag, allowing to put an upper constraint on the planetray geomtric albedo of A_g<0.2. This is the first albedo constraint for HAT-P-32b and the first albedo value for any exoplanet. Contact PI is Matthias Mallonn
