Tidal Evolution of the Planetary System around HD 83443
Two planets with an orbital period ratio of approximately 10 : 1 have been discovered around the star HD 83443. The inner and more massive planet, HD 83443b, has the smallest semimajor axis among all currently known exoplanets. Unlike other short-period exoplanets, it maintains a substantial orbital eccentricity, e1 = …
