The refined physical properties of the transiting exoplanetary system WASP-41

We present the first follow-up study of the transiting system WASP-41 after its discovery in 2011. The main goal of this paper is to refine the physical parameters of the system and search for possible signs of transit timing variations. The observations used for analysis were taken from the public archive of the Exoplanet Transit Database (ETD). Assuming three different limb darkening laws, we found the best-fitting model and redetermined parameters of the system. Although system parameters obtained in this study were found to be in good agreement with the discovery study, the planetary radius determined here is notably smaller, namely 1.12(+0.06) (-0.07) R-Jup. The Safronov number = 0.071 +/- 0.002 and equilibrium temperature T-eq = 1271 +/- 50 K were also determined. Both values indicate that the planet WASP-41b belongs to Class I of transiting planets. No significant transit timing variations were detected. ((c) 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
