Exoplanetary Scratchpad |
One of three systems discovered by Super WASP containing a transiting very hot jupiter so close to its star that it is evaporating. Like the other two, WASP-4 and 5, it is incapable of radiating away heat from its star and instead swells up to significantly larger than Jupiter. This is a planet 81% more massive than Jupiter with 13% larger radius going around in just less day 2 days. Its transit time varies by up to 3 minutes, which indicates that a further planet may be in this system. This would be a further Neptunian planet and would be the first exoplanet detected by measuring eclipse timing deviations of an earlier discovered planet (Transit Timing Variation method). Further observations are needed to confirm the planet, but the best fit is that it is in 2:1 resonance with the larger planet. Planet b found to be in a low inclination prograde orbit with respect to its star's equator.
