作品简介:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. WASP-3 is a magnitude 10 yellow-white dwarf star located about 727 light-years away in the Lyra constellation. The extrasolar planet WASP-3b was detected by the SuperWASP project in 2007. The William Herschel Telescope had confirmed it was a planet by 2008. In 2010, the possible presence of a second planet orbiting WASP-3 was inferred from timing variations in the transits of WASP-3b. The discovers note that additional observations are required to confirm the presence of this planet candidate, designated WASP-3c. The best-fit parameters for WASP-3c which match the observe timing variations suggest it is close to the outer 2:1 resonance with WASP-3b, with an orbital period of 3.72–3.78 days and a mass 15 times that of the Earth (close to the mass of Uranus). Alternative sets of parameters are possible, though they give a poorer fit to the data: a 6–10 Earth mass planet in an orbit of 3.03–3.05 days (close to the 5:3 resonance), or a 10 Earth mass planet with a period of 3.58–3.64 days (close to the 2:1 resonance) also reproduce the observed timing variations.
