Diagram of 1/10th of the escape velocity versus the equilibrium temperature Tp of the exoplanets and solar system planets/moons. The lines represent the thermal velocity of atmospheric species. The complete distribution in the graph shows a wide variety of exoplanets from cold giants at the left to the hot Jupiters to the right, small size exoplanets at the bottom and exoplanets of greater size at the top with the increasing height from the x-axis. The solar system objects are also shown.
H/He dominant atmosphere
One-tenth (1/10th) of the escape velocity-equilibrium temperature, Tp, diagram of exoplanets capable of H/He abundant atmospheres and the giant planets of the solar system. M is the mass of exoplanet and Me is the mass of Earth. The exoplanet classification we adopted shows the position of exoplanets in the graph w.r.t. their mass indicating the type of exoplanets expected of having H or He in their atmospheres.
CO2/ H2O / N2 dominant atmospheres
One-tenth (1/10th) of the escape velocity-equilibrium temperature, Tp, diagram of exoplanets capable of H2O/N2/CO2 atmosphere and the terrestrial planets of the solar system. M is the mass of exoplanet and Me is the mass of Earth. This classification shows exoplanets of different masses and categories capable of holding carbon, nitrogen or water-rich atmospheres as indicated in correlation with terrestrial planets of the solar system.
Potentially habitable exoplanets
One-tenth (1/10th) of the escape velocity-equilibrium temperature, Tp, diagram of the exoplanets of interest for habitability studies. The figure shows a conservative list of exoplanets which could be potentially habitable from the estimations of our model. The names of the exoplanets which are already considered potentially habitable are highlighted in blue.
