HAT - P - 9 b : A LOW DENSITY PLANET TRANSITING A MODERATELY FAINT F STAR 1
We report the discovery of a planet transiting a moderately faint (V = 12.3mag) late F star, with an orbital period of 3.92289 ± 0.00004days. From the transit light curve and radial velocity measurements we determine that the radius of the planet is Rp = 1.40 ± 0.06RJup and that the mass is Mp = 0.78 ± 0.09MJup. The density of the new planet, ρp = 0.35 ± 0.06 g cm , fits to the low-density tail...

We report the discovery of a planet transiting a moderately faint (V = 12.3 mag) late F star, with an orbital period of 3.92289 ± 0.00004 days. From the transit light curve and radial velocity measurements we determine that the radius of the planet is R p = 1.40 ± 0.06 R Jup and that the mass is M p = 0.78 ± 0.09 M Jup. The density of the new planet, ρ p = 0.35 ± 0.06 g cm −3 , fits to the low-...
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 کاملHAT-P-3b: A HEAVY-ELEMENT-RICH PLANET TRANSITING A K DWARF STAR
We report the discovery of a Jupiter-size planet transiting a relatively bright (V = 11.56) and metal-rich early K dwarf star with a period of ∼ 2.9 days. On the basis of follow-up photometry and spectroscopy we determine the mass and radius of the planet, HAT-P-3b, to be Mp = 0.599 ± 0.026 MJup and Rp = 0.890± 0.046 RJup. The relatively small size of the object for its mass implies the presenc...
متن کاملHAT-P-7b: AN EXTREMELY HOT MASSIVE PLANET TRANSITING A BRIGHT STAR IN THE KEPLER FIELD
We report on the latest discovery of the HATNet project; a very hot giant planet orbiting a bright (V = 10.5) star with a small semi-major axis of a = 0.0377± 0.0005AU. Ephemeris for the system is P = 2.2047299 ± 0.0000040 days, mid-transit time E = 2, 453, 790.2593 ± 0.0010 (BJD). Based on the available spectroscopic data on the host star and photometry of the system, the planet has a mass of ...
