HD 80606 b , a planet on an extremely elongated orbit ⋆
We report the detection of a planetary companion orbiting the solar-type star HD80606, the brighter component of a wide binary with a projected separation of about 2000 AU. Using high-signal spectroscopic observations of the two components of the visual binary, we show that they are nearly identical. The planet has an orbital period of 111.8 days and a minimum mass of 3.9 MJup. With e =0.927, t...
متن کاملHAT-P-2b: A SUPER-MASSIVE PLANET IN AN ECCENTRIC ORBIT TRANSITING A BRIGHT STAR
We report the discovery of HAT-P-2b, a massive (Mp = 8.17 ± 0.72 MJup) planet transiting the bright (V = 8.7) F8 star HD 147506, with an orbital period of 5.63 days and an eccentricity of e = 0.5. From the transit light curve we determine that the radius of the planet is Rp = 1.18 ± 0.16 RJup. HAT-P-2b has a mass about 9 times the average mass of previously-known transiting exoplanets, and a de...
متن کاملHD 147506b: A SUPER-MASSIVE PLANET IN AN ECCENTRIC ORBIT TRANSITING A BRIGHT STAR
We report the discovery of a massive (Mp = 9.04±0.50MJup) planet transiting the bright (V = 8.7) F8 star HD 147506, with an orbital period of 5.63341±0.00013 days and an eccentricity of e = 0.520± 0.010. From the transit light curve we determine that the radius of the planet is Rp = 0.982± 0.105RJup. HD 147506b (also coined HAT-P-2b) has a mass about 9 times the average mass of previously-known...
متن کاملLong term behavior of a hypothetical planet in a highly eccentric orbit
For a hypothetical planet on a highly eccentric orbit, we have calculated the osculating orbital parameters and its closest approaches to Earth and Moon over a period of 750 kyr. The approaches which are close enough to influence the climate of the Earth form a pattern comparable to that of the past climatic changes, as recorded in deep sea sediments and polar ice cores.
متن کامل3.6 AND 4.5 μm PHASE CURVES OF THE HIGHLY IRRADIATED ECCENTRIC HOT JUPITER WASP-14b
We present full-orbit phase curve observations of the eccentric (e ∼ 0.08) transiting hot Jupiter WASP-14b obtained in the 3.6 and 4.5 μm bands using the Spitzer Space Telescope. We use two different methods for removing the intrapixel sensitivity effect and compare their efficacy in decoupling the instrumental noise. Our measured secondary eclipse depths of 0.1882% ± 0.0048% and 0.2247% ± 0.00...
