HAT-P-7b: Extremely Hot Massive Planet - IOPscience
With orbital period of only 2.2 days, implying a semimajor axis of only 0.038 AU, HAT-P-7b is a “very hot Jupiter,” a name frequently given to giant planets with orbital period less than 3 days (see Bouchy et al. 2004).
Winds of rubies and sapphires strike the sky of giant planet
2016年12月12日 · Weather has been detected on HAT-P-7b – a planet 16x larger than Earth, over 1000 light-years away. Clouds on the planet could be made of corundum, the mineral which forms rubies and sapphires. The Kepler Space Telescope …
Title: HAT-P-7: A Retrograde or Polar Orbit, and a Third Body
2009年8月12日 · We show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86 degrees with respect to its parent star's equatorial plane, and a strong possibility of retrograde motion. We also report evidence for an …
Kepler’s Optical Phase Curve of the Exoplanet HAT-P-7b
2009年8月7日 · The data for HAT-P-7b show a smooth rise and fall of light from the planet as it orbits its star, punctuated by a drop of 130 ± 11 parts per million in flux when the planet passes behind its star. We interpret this as the phase variation of the dayside thermal emission plus reflected light from the planet as it orbits its star and is occulted.

HAT-P-7b - Astronomopedia
HAT-P-7b (or Kepler-2b) is an exotic exoplanet orbiting the star HAT-P-7, located in the zodiac constellation Cygnus. HATP-7b, discovered in 2008 by the HATNet Project telescope HAT-7, has a radius larger than Jupiter 's and an orbital plane that's tilted so much relative to its star (108°) that the planet is nearly in a polar orbit.
