ExoplANETS-A is an EU Horizon-2020 project with the primary objective of establishing new knowledge on exoplanet atmospheres. Intimately related to this topic is the study of the host-stars radiative properties […]
![[L] The planet radius histogram showing the radius gap at ∼1.8 Earth radii. The blue and red lines are kernel density estimations of the smoothed underlying distribution and identify the location of the radius separating the two planet populations (∼ 1.8), and the peaks of the two planet populations at 1.5 and 2.4 Earth radii. -- astro-ph.SR [R] The XUV flux received by planets compared to their gravitational potential in order to determine the possible atmospheric escape process following the method in Salz et al. (2016). The rapid hydrodynamical escape process applies to the left of the red dashed line. Slower, Jeans escape applies to the right of the blue solid line. Markers are crosses for planets above the radius gap and circles for planets below the radius gap. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/05/ExoplANETS-A.png?resize=1200%2C712&ssl=1)
