Escape of asteroids from the main belt [PDF]
Astronomy and Astrophysics, 2017 Aims. We locate escape routes from the main asteroid belt, particularly into the near-Earth-object (NEO) region, and estimate the relative fluxes for different escape routes as a function of object size under the influence of the Yarkovsky semimajor-axis drift.Methods.

The distribution of basaltic asteroids in the Main Belt [PDF]
Icarus, 2008 We present the observational results of a survey designed to target and detect asteroids whose colors are similar to those of Vesta family members and thus may be considered as candidates for having a basaltic composition. Fifty basaltic candidates were selected with orbital elements that lie outside of the Vesta dynamical family.

Size and Albedo Constraints for (152830) Dinkinesh Using WISE Data
The Astrophysical Journal Letters, 2023 Probing small main-belt asteroids provides insight into their formation and evolution through multiple dynamical and collisional processes. These asteroids also overlap in size with the potentially hazardous near-Earth object population and supply the ...

Taxonomic Analysis of Asteroids with Artificial Neural Networks
The Astronomical Journal, 2023 We study the surface composition of asteroids with visible and/or infrared spectroscopy. For example, asteroid taxonomy is based on the spectral features or multiple color indices in visible and near-infrared wavelengths.

CASTAway: An asteroid main belt tour and survey [PDF]
Advances in Space Research, 2018 CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the composition of these objects can be inferred from space-based remote sensing using spectroscopic techniques.

The Mid-plane of the Main Asteroid Belt [PDF]
The Astronomical Journal, 2018 Abstract We measure the mid-plane of the main asteroid belt by using the observational data of a nearly complete and unbiased sample of asteroids and find that it has inclination and longitude of ascending node

A record of planet migration in the main asteroid belt [PDF]
Nature, 2009 The main asteroid belt lies between the orbits of Mars and Jupiter, but the region is not uniformly filled with asteroids. There are gaps, known as the Kirkwood gaps, in the asteroid distribution in distinct locations that are associated with orbital resonances with the giant planets; asteroids placed in these locations follow chaotic orbits and escape

Determining the Pyroxene Mineralogies of Vestoids
The Planetary Science Journal, 2023 Bulk pyroxene compositions were calculated for a number of V-type asteroid spectra using formulae derived by Burbine et al. These formulae were derived by analyzing HED (howardite, eucrite, and diogenite) meteorites and calculate bulk Fs (mol%) and Wo ...

The Challenge of Measuring Asteroid Masses with Gaia DR2 Astrometry
The Planetary Science Journal, 2023 The Gaia second data release (DR2) contains high-accuracy astrometric measurements of thousands of solar system bodies. These measurements raise the possibility of determining asteroid masses by modeling scattering events between massive objects observed
