Millimagnitude photometry for transiting extrasolar planetary candidates. II. Transits of OGLE-TR-113-b in the optical and near-ir

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...

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 cm-3, 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. © 2007. The American Astronomical Society.
