Abstract

Theory of planet formation and comparison with observation

Highlights

  • IntroductionCombined with radial velocity measurements which yield the mass of the planet, one gets the planetary mass-radius diagram, which is an observational result of similar importance as the semimajor axis-mass diagram

  • The number of known transiting extrasolar planets is increasing rapidly

  • We have presented an updated planet formation code which allows to calculate in a self-consistent way planetary radii and luminosities during the entire formation and evolution phase

Summary

Introduction

Combined with radial velocity measurements which yield the mass of the planet, one gets the planetary mass-radius diagram, which is an observational result of similar importance as the semimajor axis-mass diagram. The reason for this is that one can derive the mean density of the planet, which constrains, at least to some extent, the internal structure which is of central importance to understand the nature (Leconte et al 2009) and, as we shall see, the formation of the planet.
