Masses of asteroids and total mass of the main asteroid belt [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractAn estimation of the mass of the main asteroid belt was made on the basis of the new version of EPM2014 ephemerides of the Institute of Applied Astronomy of Russian Academy of Sciences using about 800000 positional observations of planets and spacecraft.

Polarimetric survey of main-belt asteroids [PDF]
Astronomy & Astrophysics, 2012 Aims. We present results of a polarimetric survey of main-belt asteroids at Complejo Astronomico el Leoncito (CASLEO), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry, to estimate diversity in polarimetric properties of asteroids that belong to different taxonomic classes, and to search for objects that

The origin of planetary impactors in the inner solar system [PDF]
, 2005 New insights into the history of the inner solar system are derived from the impact cratering record of the Moon, Mars, Venus and Mercury, and from the size distributions of asteroid populations. Old craters from a unique period of heavy bombardment that

Recent arrivals to the main asteroid belt [PDF]
Celestial Mechanics and Dynamical Astronomy, 2022 AbstractThe region where the main asteroid belt is now located may have started empty, to become populated early in the history of the Solar system with material scattered outward by the terrestrial planets and inward by the giant planets. These dynamical pathways toward the main belt may still be active today.

A six-part collisional model of the main asteroid belt [PDF]
, 2014 In this work, we construct a new model for the collisional evolution of the main asteroid belt. Our goals are to test the scaling law of Benz and Asphaug (1999) and ascertain if it can be used for the whole belt.

V-type Asteroids as the Origin of Mesosiderites
The Planetary Science Journal, 2023 We present the results of a campaign of hypervelocity impact experiments on natural mesosiderite targets, using representative main asteroid belt impact speeds. The objective is to document further the surface evolution of iron-rich asteroids.

Active Asteroid 311P/PanSTARRS: Rotational Instability as the Origin of its Multitails?
The Astronomical Journal, 2023 The active asteroid 311P/PanSTARRS is one of the two targets of the planned Chinese asteroid exploration mission Tianwen-2. During 2013, 311P experienced several mass-loss events and exhibited multiple comet-like tails. Here we analyze the morphology and
