Candidate Main-belt Asteroids for Surface Heterogeneity

The Astronomical Journal
Large terrestrial bodies in our solar system like the Earth, Mars, Mercury, and the Moon exhibit geologically complex surfaces with compositional heterogeneity.

Size Distributions of Bluish and Reddish Small Main-belt Asteroids Obtained by Subaru/Hyper Suprime-Cam [PDF]

Astronomical Journal, 2021
We performed a wide-field survey observation of small asteroids using the Hyper Suprime-Cam installed on the 8.2 m Subaru Telescope. We detected more than 3000 main-belt asteroids with a detection limit of 24.2 mag in the r-band, which were classified ...

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 ...

VLT/SPHERE imaging survey of the largest main-belt asteroids: Final results and synthesis

Astronomy & Astrophysics, 2021
Context. Until recently, the 3D shape, and therefore density (when combining the volume estimate with available mass estimates), and surface topography of the vast majority of the largest (D  ≥ 100 km) main-belt asteroids have remained poorly constrained.

Thermal properties of large main-belt asteroids observed by Herschel PACS [PDF]

Astronomy & Astrophysics, 2020
Non-resolved thermal infrared observations enable studies of thermal and physical properties of asteroids via thermo-physical models provided the shape and rotational properties of the target are well determined.

Polarimetric survey of main-belt asteroids. V. The unusual polarimetric behavior of V-type asteroids [PDF]

Astronomy & Astrophysics, 2017
Aims. We present the 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

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.
