A Giant Impact as the Likely Origin of Different Twins in the Kepler-107 Exoplanet System [PDF]

open access: yes, 2019
Measures of exoplanet bulk densities indicate that small exoplanets with radius less than 3 Earth radii (R(sub )) range from low-density sub-Neptunes containing volatile elements to higher-density rocky planets with Earth-like or iron-rich (Mercury-like)
