TraMoS IV: Discarding the Quick Orbital Decay Hypothesis for OGLE-TR-113b

Abstract

In the context of the TraMoS project we present nine new transit observations of the exoplanet OGLE-TR-113b observed with the Gemini South, Magellan Baade, Danish-1.54m and SOAR telescopes. We perform a homogeneous analysis of these new transits together with ten literature transits to probe into the potential detection of an orbital decay for this planet reported by \citet{adams2010}. Our new observations extend the transit monitoring baseline for this system by 6 years, to a total of more than 13 years. With our timing analysis we obtained a $\dot{P}=-1.0\pm 6.0$ ms~yr${}^{-1}$, which rejects previous hints of a larger orbital decay for OGLE-TR-113b. With our updated value of $\dot{P}$ we can discard tidal quality factors of $Q_{\star }<10^5$ for its host star. Additionally, we calculate a 1$\sigma$ dispersion of the Transit Timing Variations (TTVs) of 42 seconds over the 13 years baseline, which discards additional planets in the system more massive than $0.5-3.0M_{\oplus }$ in 1:2, 5:3, 2:1 and 3:1 Mean Motion Resonances with OGLE-TR-113b. Finally, with the joint analysis of the 19 light curves we update transit parameters, such as the relative semi-major axis $a/R_s=6.44_{-0.05}^{+0.04}$, the planet-to-star radius ratio $R_p/R_s=0.14436_{-0.00088}^{+0.00096}$, and constrains its orbital inclination to $i=89.27_{-0.68}^{+0.51}$~degrees.
