Abstract

Abstract We present a near-infrared transmission spectrum of the long-period ( P = 542 days), temperate ( T eq = 294 K) giant planet HIP 41378 f obtained with the Wide-Field Camera 3 instrument aboard the Hubble Space Telescope (HST). With a measured mass of 12 ± 3 M ⊕ and a radius of 9.2 ± 0.1 R ⊕ ...
