Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered soExpand
The fossilized size distribution of the main asteroid belt
Planet formation models suggest the primordial main belt experienced a short but intense period of collisional evolution shortly after the formation of planetary embryos. This period is believed toExpand
Linking the collisional history of the main asteroid belt to its dynamical excitation and depletion
Abstract The main belt is believed to have originally contained an Earth mass or more of material, enough to allow the asteroids to accrete on relatively short timescales. The present-day main belt,Expand
A sawtooth-like timeline for the first billion years of lunar bombardment
Abstract We revisit the early evolution of the Moon's bombardment. Our work combines modeling (based on plausible projectile sources and their dynamical decay rates) with constraints from the lunarExpand
An Archaean heavy bombardment from a destabilized extension of the asteroid belt
TLDR
It is reported that the Late Heavy Bombardment lasted much longer than previously thought, with most late impactors coming from the E belt, an extended and now largely extinct portion of the asteroid belt between 1.7 and 2.1 astronomical units from Earth. Expand
Velocity Distributions among Colliding Asteroids
Abstract The probability distribution for impact velocities between two given asteroids is wide, non-Gaussian, and often contains spikes according to our new method of analysis in which each possibleExpand
Asteroids Were Born Big
Abstract How big were the first planetesimals? We attempt to answer this question by conducting coagulation simulations in which the planetesimals grow by mutual collisions and form larger bodies andExpand
COMETARY ORIGIN OF THE ZODIACAL CLOUD AND CARBONACEOUS MICROMETEORITES. IMPLICATIONS FOR HOT DEBRIS DISKS
The zodiacal cloud is a thick circumsolar disk of small debris particles produced by asteroid collisions and comets. Their relative contribution and how particles of different sizes dynamicallyExpand
The recent breakup of an asteroid in the main-belt region
TLDR
The discovery of a family of asteroids that formed in a disruption event only 5.8 ± 0.2 million years ago, and which has subsequently undergone little dynamical and collisional evolution, is reported. Expand
Recent Origin of the Solar System Dust Bands
Infrared Astronomical Satellite (IRAS) observations in 1983 revealed the existence of several solar system dust bands. These dust bands are believed to be debris produced by recent disruption eventsExpand
