Diversities and similarities exhibited by multi-planetary systems and their architectures: II. Radii of singles and multis
Alexandra Muresan, Carina M. Persson, Malcolm Fridlund
The discovered planets in apparent single-planet systems (singles) and those in systems with multiple detected planets (multis) exhibit a rich diversity of physical and orbital pro…

Diversities and similarities exhibited by multi-planetary systems and their architectures: I. Orbital spacings
Alexandra Muresan, Carina Persson, Malcolm Fridlund
The rich diversity of multi-planetary systems and their architectures is greatly contrasted by the uniformity exhibited within many of these systems. Previous studies have shown th…
