New Insights into the Mysterious Gap in the Size Distribution of Super-Earths

Recent simulations have shed light on the deviation of some planets from their original birthplaces, providing insights into the relatively low number of exoplanets with sizes around two Earth radii, also known as the radius valley or gap. Remo Burn, an exoplanet researcher at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, and lead author of the article published in Nature Astronomy, highlighted the shortage of exoplanets with sizes around two Earth radii, a phenomenon discovered six years ago through a reanalysis of data from the Kepler space telescope. These findings open new avenues for understanding the dynamics of planetary systems and the factors influencing the size distribution of exoplanets.
