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.

WASP-19b 是一顆位於船帆座的太陽系外行星，它因為是目前已確認公轉週期最短的系外行星而聞名，週期只有0.7888399日或18.932小時。 WASP-19b的質量相當接近 木星 （1.15倍 木星質量），但其半徑卻比木星大許多（1.31倍木星半徑或0.13倍 太陽半徑）；這使得它的體積相當於低質量恆星 [1]。 它的母恆星是位於 船帆座 的 WASP-19。 目前WASP-19b是軌道周期很短的熱木星 …

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.

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

2009年12月9日 · We report on the discovery of a new extremely short period transiting extrasolar planet, WASP-19b. The planet has mass Mpl = 1.15 ± 0.08 MJ, radius Rpl = 1.31 ± 0.06 RJ, and orbital period P = 0.7888399 ± 0.0000008 days.

1997年10月1日 · Among the USP gas giant planets, WASP-19 b, with an orbital period of 0.78 days, has emerged as a prime target for the search for orbital decay using transit timings [22, 23, 24, 25]. Some studies predict a measurable effect on WASP-19 b’s transit times after 10 years.

We report an analysis of transit spectroscopy of the extrasolar planets WASP-12 b, WASP-17 b, and WASP-19 b using the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST). We analyze the data for a single transit for each planet using a strategy similar, in certain aspects, to the techniques used by Berta et al., but we

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 =...
