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 ...

Context. The orbital element distribution of the inner main belt (IMB) provides clues to the origin of the main-belt asteroids. Mars-crossing asteroids (MCAs) and near-Earth objects (NEOs) can provide some references to validate and improve theoretical ...

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 ...

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.

Earth-approaching asteroids: Populations, origin, and compositional types [PDF]
, 1978 Origin, physical properties, and discovery history of smaller asteroids are reviewed. They appear to link the main belt objects, namely the comets and meteorites.

A photometric search for active Main Belt asteroids
, 2014 It is well known that some Main Belt asteroids show comet-like features. A representative example is the first known Main Belt comet 133P/(7968) Elst-Pizarro. If the mechanisms causing this activity are too weak to develop visually evident comae or tails,

The Planetary Science JournalCarbon-rich (C-complex) asteroids provide insight into the early solar system, and families of C-complex asteroids serve as robust samples for learning about the internal structure of planetesimals and the materials of the protoplanetary disk.

Subaru Lightcurve Observations of Sub-km-sized Main-belt Asteroids
, 2014 Investigations of the spin period and shape distributions for a certain asteroid group using their lightcurve observations are essential to understand collisional evolution of that group.

The Volatile Composition and Activity Evolution of Main-belt Comet 358P/PANSTARRS
The Planetary Science JournalWe report the detection of water vapor associated with main-belt comet 358P/PANSTARRS on UT 2024 January 8–9 using the NIRSPEC instrument on board JWST.
