Dynamics and habitability of the TESS circumbinary systems TOI-1338 and TIC-172900988
Nikolaos Georgakarakos
Two circumbinary planets have been recently discovered by TESS. The main aim of this work is to explore whether it is possible, besides the discovered circumbinary planet, to have…
Protoplanet Collisions: Statistical Properties of Ejecta
Samuele Crespi, Ian Dobbs-Dixon, Nikolaos Georgakarakos +4
The last phase of the formation of rocky planets is dominated by collisions among Moon- to Mars-sized planetary embryos. Simulations of this phase need to handle the difficulty of…
Long-term dynamical survival of deep Earth coorbitals
Apostolos A. Christou, Nikolaos Georgakarakos
We investigate the long-term dynamical survival of Earth co-orbital asteroids, focusing on near-circular, near-planar orbits which existing studies suggest are the most stable. Thr…
The entry geometry and velocity of planetary debris into the Roche sphere of a white dwarf
Dimitri Veras, Nikolaos Georgakarakos, Alexander J. Mustill +3
Our knowledge of white dwarf planetary systems predominately arises from the region within a few Solar radii of the white dwarfs, where minor planets break up, form rings and discs…
Circumbinary habitable zones in the presence of a giant planet
Nikolaos Georgakarakos, Siegfried Eggl, Dobbs-Dixon
Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions. The co…
