WASP-19b, formally named Banksia, [2] is an exoplanet, notable for possessing one of the shortest orbital periods of any known planetary body: 0.79 days or approximately 18.932 hours. It has a mass close to that of Jupiter (1.15 Jupiter masses ), but by comparison has a much larger radius (1.31 times that of Jupiter, or 0.13 Solar radii ...

2024年10月24日 · WASP-19 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.154 Jupiters, it takes 0.8 days to complete one orbit of its star, and is 0.01652 AU from its star. Its discovery was announced in 2009.

In December 2009, the SuperWASP project announced that a hot Jupiter type exoplanet, WASP-19b, was orbiting very close to this star and with the shortest orbital period of any transiting exoplanet known at the time.

Investigating giant planet migration history via improved eccentricity and mass determination for 231 transiting planets. New and updated stellar parameters for 90 transit hosts. The effect of the surface gravity.

WASP-19 b is an exoplanet orbiting the star WASP-19, located about 869.4 light-years (266.6 pc) away from Solar System. Its discovery was publicly announced on 2009. The host star WASP-19 has apparent magnitude of 12.3, with absolute magnitude of 5.2.

The plot for WASP-19b shows a loop with a marked excursion to the right, suggesting a cloudy night side to the planet. For WASP-18b, however, the loop follows a trajectory nearer the blue “no cloud” track, suggesting a clearer atmosphere.

Currently, WASP-4 and WASP-12 stand out as the most promising candidates exhibiting TTVs. We have presented here the transit timing variation analysis of the exoplanet WASP-19 b, one of the first detected ultra-short-period gas-giant planets.

2024年10月10日 · WASP-19 b is a Confirmed extrasolar planet (exoplanet) that orbits the star WASP-19 in the constellation of Vela

WASP-19b is an extrasolar planet. It has one of the shortest orbital periods of any known planet. Its orbital period is approximately 18.932 hours. It is much 1.31 times larger than Jupiter. It orbits the star WASP-19 in the Vela constellation. [1] .

2010年1月3日 · We report on the discovery of a new extremely short period transiting extrasolar planet, WASP-19b. The planet has mass Mpl = 1.15 \pm 0.08 MJ, radius Rpl = 1.31 \pm 0.06 RJ, and orbital period P =...
