Abstract (from CDS):

We present precise V- and Ks-band transit photometry for the planetary host star OGLE-TR-113. Using the Ks-band photometry, we confirm the dwarf nature of OGLE-TR-113 and obtain new estimates for its effective temperature, distance, and reddening. We employ the V-band photometry to obtain planetary and orbit parameters from the transit fit, a=0.0232±0.0038 AU, orbital period P=1.4324752±0.0000015 day, i=86.7-90, and Rp=1.09±0.09 RJ. These values are in excellent agreement with previous works. Assuming a mass Mp=1.32±0.19 MJ for the planet, we obtain its mean density ρ=1.26±0.50 g/cm3, also in agreement with previous works. The transit observed in the Ks band has a larger scatter, and we find its amplitude to be consistent with that in the V band. In this way, we find an independent confirmation of the planetary nature of OGLE-TR-113b.
