Hubble transit spectrum of the habitable-zone super-Earth LHS 1140 b

In Edwards et al. (2020) we present the analysis of Hubble WFC3 observations of a temperate super-Earth. With a radius of 1.7 R⊕ and a density of 7.5 g/cm−3, LHS 1140 b is likely to be a rocky world and, with an equilibrium temperature of ∼235 …

K2-18 b is so far the smallest habitable-zone world with a confirmed water vapour detection (Tsiaras et al. 2019).

This detection has sparked intense debate regarding the nature of this world: water world or sub-Neptune? Seemingly sitting in the sub-Neptune region of the radius valley, the internal structure of K2-18b …
