我们报告了低密度凌日行星WASP-31 b的发现。它的质量是0.48木星质量，半径是1.55木星半径。它在一个3.4天的轨道上围绕着一颗贫金属的晚F型，V = 11.7的矮星星星，这是一个共同的自行对的成员。就其低密度而言，WASP-31 b仅次于WASP-17 b，后者是一颗质量相似的辐射更高的行星。
We report the discovery of the low-density, transiting gian t planet WASP-31b. The planet is 0.48 Jupiter masses and 1.55 Jupiter radii. It is in a 3.4-day orbit around a metal-poor, late-F-type, V = 11.7 dwarf star, which is a member of a common proper motion pair. In terms of its low density, WASP-31b is second only to WASP-17b, which is a more highly irradiated planet of similar mass.
