Automated Classification of Asteroids into Families at Work
It is demonstrated how by the new approach the asteroid family classification becomes stable in general terms (converging towards a permanent list of confirmed families), and in the same time evolving in details (to account for the newly discovered asteroids) at each update.
Asteroid family ages
Machine learning classification of new asteroid families members
Asteroid families are groups of asteroids that are the product of collisions or of the rotational fission of a parent object. These groups are mainly identified in proper elements or frequencies
Machine-learning identification of asteroid groups
Asteroid families are groups of asteroids that share a common origin. They can be the outcome of a collision or be the result of the rotational failure of a parent body or its satellites.
Families classification including multiopposition asteroids
Abstract In this paper we present the results of our new classification of asteroid families, upgraded by using catalog with > 500,000 asteroids. We discuss the outcome of the most recent update of
Color study of asteroid families within the MOVIS catalog
The aim of this work is to study the compositional diversity of asteroid families based on their near-infrared colors, using the data within the MOVIS catalog. As of 2017, this catalog presents data
An automatic approach to exclude interlopers from asteroid families
Asteroid families are valuable source of information to many asteroid-related re- searches, assuming a reliable list of their members could be obtained. However, as the number of known asteroids
Volume and mass distribution in selected asteroid families
The main focus of this paper is calculation of the diameters of asteroids belonging to five families (Vesta, Eos, Eunomia, Koronis, and Themis). To do that, we used the HCM algorithm applied for a
Asteroids 87887 – 415992: the youngest known asteroid pair?
Context. Pairs of asteroids, that is, couples of single bodies on tightly similar heliocentric orbits, were recently postulated as a new category of objects in the solar system. They are believed to


A multidomain approach to asteroid families’ identification
Previous works have identified families halos by an analysis in proper elements domains, or by using Sloan Digital Sky Survey-Moving Object Catalog data, fourth release (SDSS-MOC4) multi-band
Asteroid Families: Search of a 12,487-Asteroid Sample Using Two Different Clustering Techniques
A sample of over 12,487 asteroid proper element triplets, computed by A. Milani and Z. Kneževic (1994, Icarus 107, 219-254), has been searched for statistically significant and robust families by
Using albedos from WISE/NEOWISE to separate distinct albedo groups within the Main Belt asteroids, we apply the Hierarchical Clustering Method to these subpopulations and identify dynamically
Proper element catalogs and asteroid families
Using the synthetic theory, we computed proper elements for asteroids in the inner part of the main belt and in the trans-Neptunian region. We present the new results and we discuss some important
Yarkovsky footprints in the Eos family
Interlopers within Asteroid Families
Abstract A statistical method for the evaluation of the probable amount of interlopers included in the most recently identified asteroid families is developed. The method is based on the analysis of
