Identification and Dynamical Properties of Asteroid Families
, 2015 Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts over the age of the Solar System ...

Main-belt comets: sublimation-driven activity in the asteroid belt [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractOur knowledge of main-belt comets (MBCs), which exhibit comet-like activity likely due to the sublimation of volatile ices, yet orbit in the main asteroid belt, has increased greatly since the discovery of the first known MBC, 133P/Elst-Pizarro, in 1996, and their recognition as a new class of solar system objects after the discovery of two ...

Modelling of asteroid formation in planetary vortex and calculation its orbital parameters
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2015 The theory of planetary vortex as the initial state of creation of the star systems is used to the study of conditions of formation of asteroids and calculation its orbital parameters.

Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra
The Astrophysical Journal LettersMost near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...

Reconstructing the size distribution of the primordial Main Belt
, 2017 In this work we aim to constrain the slope of the size distribution of main-belt asteroids, at their primordial state. To do so we turn out attention to the part of the main asteroid belt between 2.82 and 2.96~AU, the so-called "pristine zone", which has

The Lifetime of Ice on Main Belt Asteroids
The Astrophysical Journal, 2008 We theoretically estimate the loss rate of buried ice from spherical bodies 2-3.3 AU from the Sun. The loss rate is explored as a function of about a dozen parameters. We introduce the concept of a "buried snow line," where the loss of ice is sufficiently slow over the age of the solar system.
