C.; Moutou, C.; Diaz, R. F.; Gieren, W.; Gillon, M.; Hoyer, S.; Mayor, M.; Mazeh, T.; Minniti, D.; Pietrzynski, G.; Queloz, D.; Ramirez, S.; Ruiz, M. T.; Shporer, A.; Tamuz, O.; Udry, S.; Zoccali, M.; Kubiak, M.; Szymanski, M. K.; Soszynski, I.; Szewczyk, O.; Ulaczyk, K.; Wyrzykowski, L.We present results of the photometric campaign for planetary and low-luminosity object transits conducted by the OGLE survey in the 2005 season (Campaign #5). About twenty of the most promising candidates discovered in these data were subsequently verified spectroscopically with the VLT/FLAMES spectrograph.
- ItemThe "666" collaboration on OGLE transits I.: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry(2007) Pont, F.; Moutou, C.; Gillon, M.; Udalski, A.; Bouchy, F.; Fernandes, J. M.; Gieren, W.; Mayor, M.; Mazeh, T.; Minniti, D.; Melo, C.; Naef, D.; Pietrzynski, G.; Queloz, D.; Ruiz, M. T.; Santos, N. C.; Udry, S.Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. Here we report new high-accuracy photometry of the transits of OGLE-TR-10 and OGLE-TR-56 with VLT/FORS1. One transit of each object was covered in Bessel V and R filters, and treated with the deconvolution-based photometry algorithm DECPHOT, to ensure accurate millimagnitude light curves. Together with earlier spectroscopic measurements, the data imply a radius of 1.22(-0.07)(+0.12) R-J for OGLE-TR-10b and 1.30 +/- 0.05 R-J for OGLE-TR-56b. A re-analysis of the original OGLE photometry resolves an earlier discrepancy about the radius of OGLE-TR-10. The transit of OGLE-TR-56 is almost grazing, so that small systematics in the photometry can cause large changes in the derived radius. Our study confirms both planets as inflated hot Jupiters, with large radii comparable to that of HD 209458b and at least two other recently discovered transiting gas giants.
