We use simulated planetary systems to model the planet multiplicity of Kepler stars. Previous studies have underproduced single planet systems and invoked the so-called Kepler dichotomy, where the planet forming ability of a Kepler star is dichotomous, producing either few or many transiting planets. In this paper, we show that the Kepler dichotomy is only required when the inner part of planetary discs are just assumed to be flared. When the inner part of planetary discs are flat, we reproduce...[Show more]
