TL;DR: In this article, the authors present new calculations of transit spectra of super-Earths that allow for atmospheres with arbitrary proportions of common molecular species and haze, and test this method with generic spectra, reproducing the expected systematics and absorption features, then apply it to the nearby super-Earth GJ 1214b.

TL;DR: In this article, a decomposition of a super-Earth/sub-Neptune regime for which both radius and mass are measured is presented, where each is partitioned into a solid core and gaseous envelope, associating a specific core mass and envelope mass with a given exoplanet.

TL;DR: In this article, a super-Earth HD 97658 b is confirmed to have transited its host star, based on Spitzer transit observations, and a Bayesian global analysis of Keck-High Resolution Echelle Spectrometer (Keck-HIRES) radial velocities and Microvariability and Oscillations of STars (MOST) and Spitzer photometry is carried out.

TL;DR: In this paper, the structural evolution of super-Earth and mini-Neptune-type exoplanets with H2-He envelopes was studied, incorporating radiative cooling and XUV-driven mass loss.
