WebThe mass is in solar masses, the radius in kilometers. With the lighter color is the result from general relativity. With the darker color is the result from minimal dilatonic gravity for the star ... Our analysis suggests that the transition between large and small planets occurs at a mass (radius) of 124 ± 7 M⊕ (12.1 ± 0.5 R⊕). As expected, we established two mass-radius relations for exoplanets. For low-mass planets, the radius increases with increasing mass, and the M-R relation we derive is R ∝ M0.55 ± … Ver más Exoplanet studies have now reached the level at which planet characterization is possible. There are hundreds of planets with measured masses and radii. Knowledge of these … Ver más The data we use include only planets with masses and radii that are based directly on observations, as opposed to being inferred from planetary … Ver más Using the approach we outlined in the previous section, we obtained estimates for the two slopes, and the breakpoint. We found the breakpoint … Ver más The model we assume is that of two mass regimes that differ by the M-R power law.
