Near-Earth asteroids in Main Belt-crossing orbits
P. S. Zain, R. P. Di Sisto, R. Gil-Hutton
We study the dynamical and collisional evolution of Near-Earth asteroids (NEAs) in Main Belt-crossing orbits (NEACs). We select NEACs with H < 18 and integrate their orbits for 1e7…
Collisional study of Hilda and quasi-Hilda asteroids
P. S. Zain, R. P. Di Sisto, R. Gil-Hutton
The Hilda asteroids are located in the outer main belt in a stable 3:2 mean-motion resonance with Jupiter, while the quasi-Hildas (qH) have similar orbits but are not directly unde…
Impacts on Ceres and Vesta: Source regions, cratering, and fragmentation
Patricio Zain, Romina Di Sisto, Gonzalo de Elia
We perform a study on the impacts on Ceres and Vesta. We aim to determine the size-frequency distribution (SFD) of impactors and to identify and quantify the contribution of each s…
New multi-part collisional model of the main belt: The contribution to near-Earth asteroids
P. S. Zain, G. C. de Elía, R. P. Di Sisto
Aims. We developed a six-part collisional evolution model of the main asteroid belt (MB) and used it to study the contribution of the different regions of the MB to the near-earth…
Planetary formation and water delivery in the habitable zone around solar-type stars in different dynamical environments
Patricio Salvador Zain, Gonzalo Carlos de Elía, María Paula Ronco +1
Aims. We study the formation and water delivery of planets in the habitable zone (HZ) around solar-type stars. In particular, we study different dynamical environments that are def…
