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 .
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 - 3.0 ~ { } M _ { \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 ^ { +0.04 } _ { -0.05 } , the planet-to-star radius ratio R _ { p } / R _ { s } = 0.14436 ^ { +0.00096 } _ { -0.00088 } , and constrains its orbital inclination to i = 89.27 ^ { +0.51 } _ { -0.68 } degrees .
