Millimagnitude photometry for transiting extrasolar planetary candidates. III. Accurate radius and period for OGLE-TR-111-b1
We present accurate V-band photometry for a planetary transit of OGLE-TR-111 acquired with VIMOS at the ESO Very Large Telescope. The measurement of this transit allows us to refine the planetary radius, obtaining R p = 1.01 ± 0.06 RJ. Given the mass of Mp = 0.53 MJ previously measured from radial v...
