The ” missing link ” : a 4 - day period transiting exoplanet around OGLE - TR - 111 ⋆
We report the discovery of a transiting hot Jupiter around OGLE-TR-111, from our radial velocity follow-up of OGLE transiting candidates in Carina. The planet has a mass of 0.53 ± 0.11 M J and a radius of 1.0 +0.13 −0.06 R J. Three transiting exoplanets have already been found among OGLE candidates, all with periods near 1.5 days. The planet presented here, with P = 4.0 days, is the first exopl...
متن کاملtransiting extrasolar giant planet around the star OGLE - TR - 10
We report a transiting extrasolar giant planet around the star OGLE-TR-10 (orbital period = 3.1 days), which was uncovered as a candidate by the OGLE team in their photometric survey towards the Galactic center (Udalski et al. 2002a). We observed OGLE-TR-10 spectroscopically over a period of two years (2002–2004) using the HIRES instrument with an iodine cell on the Keck I telescope, and measur...
متن کاملSearch for Double Transit Extrasolar Planetary Systems: Another Transiting Planet Around OGLE-TR-111 or a False Positive Detection?
The search for double transit planetary systems opens new possibilities for the transit searches and for studies of orbital stability, stellar irradiation, and migration scenarios, among others. We explore the OGLE lightcurves of stars with confirmed planetary companions (OGLE-TR-10, OGLE-TR-56, OGLE-TR-111, OGLE-TR-113, and OGLE-TR-132), searching for additional transits. The most promising ca...

متن کاملOGLE-TR-3: A Possible New Transiting Planet
Recently, 59 low-luminosity object transits were reported from the Optical Gravitational Lensing Experiment (OGLE). Our follow-up low-resolution spectroscopy of 16 candidates provided two objects, OGLE-TR-3 and OGLE-TR-10, which have companions with radii compatible with those of gas-giant planets. Further high-resolution spectroscopy revealed a very low velocity variation (< 500 m s) of the ho...
