Exoplanet Orbital Distribution Around FGK Sun-like Host Stars II: A Valley In The Orbital Semi-major Axis Distribution Of Sub-Neptunes
More than one hundred years ago, physics has been revolutionized when people realized that electronic orbitals, or electromagnetic interactions in general, are quantized. Now, in this study, we are presenting […]
