KELT-11b is an exoplanet orbiting around the yellow subgiant star KELT-11 (HD 93396) about 320 light-years away from Earth. It is an inflated planet, one of the "puffiest planets" (lowest-density) known, as a result of its close orbiting distance with its parent star. It has a radius 1.37 times that of Jupiter, but only 19% of its mass. It was ...

2024年10月24日 · KELT-11 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.171 Jupiters, it takes 4.7 days to complete one orbit of its star, and is 0.06229 AU from its star. Its discovery was announced in 2017.

kelt-11b是一顆環繞黃色次巨星kelt-11的太陽系外行星，距離地球約320光年。 該行星是其中一顆體積巨大的「蓬鬆行星」，其半徑為 木星 的1.37倍，但質量只有地球的19% 。

2017年4月18日 · KELT-11b is an extremely inflated planet (Figure 10), with a density of just g cm −3. This makes KELT-11b the third lowest-density planet ever discovered with a precisely measured mass and radius (those with parameter uncertainties <20%).

We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright (V = 8.0) subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star with T

2017年5月16日 · KELT-11b is an extreme version of a gas planet, like Solar System’s Jupiter or Saturn, but is orbiting very close to its host star in an orbit that lasts less than 5 days.

2016年7月6日 · We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright ($V=8.0$) subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star...

它拥有一个蓬松的气态行星KELT-11b，其大小比木星大30％，而其轨道比水星离太阳的距离要近得多。这颗恒星的光曲线显示出明显的倾角，这是由KELT-11b历时8小时进行的，这使科学家能够非常精确地确定行星的直径：181,600 km –不确定度不到4300 km。

2020年4月16日 · The light curve of this star shows a clear dip caused by the eight hour-long transit of KELT-11b, which enabled scientists to determine very precisely the diameter of the planet: 181 600 km – with an uncertainty just under 4300 km.

We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright (V = 8.0) subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star with T_(eff) = 5370±51 K, M∗ = 1.438^(+0.061)_(−0.052) M⊙, R∗ = 2.72^(+0.21)_(−0.17) R⊙, log g∗= 3.727^(+0.040)_(−0.046), and [Fe/H ...
