Two new ” very hot Jupiters ” among the OGLE transiting candidates
As a result of a radial velocity follow-up of OGLE planetary transit candidates in Carina, we report the discovery of two new transiting planets with very short orbital periods: OGLE-TR-113 with m=1.35 ±0.22M Jup , r=1.08 −0.13 R Jup , P=1.69 day. These detections bring to three the number of known " very hot Jupiters " (Jovian exoplanets like OGLE-TR-56 with periods much smaller than 3 days), ...
متن کاملElodie metallicity - biased search for transiting Hot Jupiters ⋆
We report the discovery of a new planet candidate orbiting the subgiant star HD 118203 with a period of P = 6.1335 days. The best Keplerian solution yields an eccentricity e = 0.31 and a minimum mass m 2 sin i = 2.1 M Jup for the planet. This star has been observed with the ELODIE fiber-fed spectrograph as one of the targets in our planet-search programme biased toward high-metallicity stars, o...
متن کاملELODIE metallicity - biased search for transiting Hot Jupiters ⋆ II . A very hot Jupiter transiting the bright K star HD 189733
Among the 160 known exoplanets, mainly detected in large radial-velocity surveys, only 8 have a characterization of their actual mass and radius thanks to the two complementary methods of detection: radial velocities and photometric transit. We started in March 2004 an exoplanet-search programme biased toward high-metallicity stars which are more frequently host extra-solar planets. This survey...
متن کاملHAT-P-44b, HAT-P-45b, AND HAT-P-46b: THREE TRANSITING HOT JUPITERS IN POSSIBLE MULTI- PLANET SYSTEMS
We report the discovery by the HATNet survey of three new transiting extrasolar planets orbiting moderately bright (V=13.2, 12.8 and 11.9) stars. The planets have orbital periods of 4.3012, 3.1290, and 4.4631 days, masses of 0.39, 0.89, and 0.49MJ, and radii of 1.28, 1.43, and 1.28RJ. The stellar hosts have masses of 0.94, 1.26, and 1.28M⊙. Each system shows significant systematic variations in...
متن کاملThermal Emission from Transiting Very-Hot Jupiters: Prospects for Ground-based Detection at Optical Wavelengths
Very hot Jupiters (VHJs) are defined as Jupiter-mass extrasolar planets with orbital periods shorter than three days. For low albedos the effective temperatures of irradiated VHJs can reach 2500–3000 K. Thermal emission from VHJs is therefore potentially strong at optical wavelengths. We explore the prospects of detecting optical-wavelength thermal emission during secondary eclipse with existin...
