         "The size-frequency distribution of primordial asteroids"

          utorak, 10. maj 2016. godine, u 18 sati, u ucionici 809.

Abstract:
One of the reasons for which asteroids are subject of many studies is
that they represent what is left over of the original population of
planetesimals in the inner Solar System. Among the many properties of
asteroids, their size-frequency distribution (SFD) may be diagnostic of
the process by which planetesimals formed. Taking advantage of the
existence of the so-called "Pristine zone", a low density part of the
main asteroid belt, remove asteroid family members to obtain the SFD of
the background asteroid population. We then compare the SFD of the
neighboring regions to that of the pristine zone, in order to understand
the collisional history of the main-belt. Finally, using the
size-dependent collisional probabilities of asteroids throughout the age
of the solar system, we set a constrain on the SFD of the primordial
population of planetesimals in the solar system.
