Resumen
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 ¼ 0:0232 0:0038 AU, orbital period P ¼ 1:4324752 0:0000015 day, i ¼ 86:7Y90, and Rp ¼ 1:09 0:09 RJ. These values are in excellent agreement with previous works. Assuming a mass Mp ¼ 1:32 0:19 MJ for the planet, we obtain its mean density ¼ 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.
