Title: FIVE NEW TRANSIT EPOCHS OF THE EXOPLANET OGLE-TR-111b

Abstract

We report five new transit epochs of the extrasolar planet OGLE-TR-111b, observed in the v-HIGH and Bessell I bands with the FORS1 and FORS2 at the ESO Very Large Telescope between 2008 April and May. The new transits have been combined with all previously published transit data for this planet to provide a new transit timing variations (TTVs) analysis of its orbit. We find no TTVs with amplitudes larger than 1.5 minutes over a four-year observation time baseline, in agreement with the recent result by Adams et al. Dynamical simulations fully exclude the presence of additional planets in the system with masses greater than 1.3, 0.4, and 0.5 M{sub +} at the 3:2, 1:2, and 2:1 resonances, respectively. We also place an upper limit of about 30 M{sub +} on the mass of potential second planets in the region between the 3:2 and 1:2 mean-motion resonances.
