Why a World State is Unavoidable in Planetary Defense: On Loopholes in the Vision of a Cosmopolitan Governance [PDF]
, 2019 The main claim of this chapter is that planetary defense against asteroids cannot be implemented under a decentralized model of democratic global governance, as espoused elsewhere in this book.

Development of virtual morphometric globes using Blender
, 2015 Virtual globes - programs implementing interactive three-dimensional (3D) models of planets - are increasingly used in geosciences. Global morphometric models can be useful for tectonic and planetary studies.

On the Dynamics of Comets in Extrasolar Planetary Systems
, 2019 Since very recently, we acquired knowledge on the existence of comets in extrasolar planetary systems. The formation of comets together with planets around host stars now seems evident.

Excitation and Propagation of Eccentricity Disturbances in Planetary Systems
, 2004 The high eccentricities of the known extrasolar planets remain largely unexplained. We explore the possibility that eccentricities are excited in the outer parts of an extended planetary disk by encounters with stars passing at a few hundreds of AU ...

Formation of terrestrial planets in close binary systems: the case of Alpha Centauri A
, 2002 At present the possible existence of planets around the stars of a close binary system is still matter of debate. Can planetary bodies form in spite of the strong gravitational perturbations of the companion star?
