Aqueous alteration on main belt primitive asteroids: Results from visible spectroscopy
Icarus, 2014 This work focuses on the study of the aqueous alteration process which acted in the main belt and produced hydrated minerals on the altered asteroids.

A spectroscopic comparison of HED meteorites and V-type asteroids in the inner Main Belt [PDF]
Icarus, 2010 V-type asteroids in the inner Main Belt (a < 2.5 AU) and the HED meteorites are thought to be genetically related to one another as collisional fragments from the surface of the large basaltic asteroid 4 Vesta.

Numerical simulations suggest asteroids (101955) Bennu and (162173) Ryugu are likely second or later generation rubble piles [PDF]
Nature CommunicationsRubble pile asteroids are widely understood to be composed of reaccumulated debris following a catastrophic collision between asteroids in the main asteroid belt, where each disruption can make a family of new asteroids.

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.

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

Thermal Properties of 1847 WISE-observed Asteroids
The Planetary Science Journal, 2022 We present new thermophysical model fits of 1847 asteroids, deriving thermal inertia, diameter, and Bond and visible geometric albedo. We use thermal flux measurements obtained by the Wide-field Infrared Survey Explorer (WISE) during its fully cryogenic ...

Asteroid family identification using the Hierarchical Clustering Method and WISE/NEOWISE physical properties [PDF]
, 2013 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 associated clusters of asteroids. While this survey is limited

Detectability of the Yarkovsky Effect in the Main Belt
The Planetary Science Journal, 2023 We attempt to detect a signal of Yarkovsky-related acceleration in the orbits of 134 main belt asteroids (MBAs) we observed with the University of Hawai’i 88 inch telescope, supplemented with observations publicly available from the Minor Planet Center ...
