Taxonomic Classification of Asteroids Using the KMTNet Multiband Photometry Data Set
The Planetary Science Journal, 2023 We report the multiband photometry of asteroids observed over 14 nights from 2015 December to 2017 December using the Korea Microlensing Telescope Network telescopes with the taxonomic classification of those objects. The data set contains the photometry

OBSERVED ASTEROID SURFACE AREA IN THE THERMAL INFRARED [PDF]
The Astronomical Journal, 2017 ABSTRACT The rapid accumulation of thermal infrared observations and shape models of asteroids has led to increased interest in thermophysical modeling. Most of these infrared observations are unresolved. We consider what fraction of an asteroid’s surface area contributes the bulk of the emitted thermal flux for two model asteroids of ...

Isolating the mechanisms for asteroid surface refreshing
Icarus, 2023 Evidence is seen for young, fresh surfaces among Near-Earth and Main-Belt asteroids even though space-weathering timescales are shorter than the age of the surfaces. A number of mechanisms have been proposed to refresh asteroid surfaces on short timescales, such as planetary encounters, YORP spinup, thermal degradation, and collisions.

Thermophysical Modeling of Asteroid (15) Eunomia from Spatially Resolved ALMA and VLA Data
The Planetary Science JournalAsteroid (15) Eunomia is the largest S-type asteroid in the main belt and the largest member of the Eunomia asteroid family. Previous visible-to-mid-infrared data suggested that Eunomia’s hemispheres have different olivine-to-pyroxene ratios and that ∼2%

Compositional characterisation of the Themis family
, 2015 Context. It has recently been proposed that the surface composition of icy main-belt asteroids (B-,C-,Cb-,Cg-,P-,and D-types) may be consistent with that of chondritic porous interplanetary dust particles (CPIDPs). Aims.

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids
The Astrophysical JournalThe surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.

, 2009 Mutual event observations between the two components of 90 Antiope were carried out in 2007-2008. The pole position was refined to lambda0 = 199.5+/-0.5 eg and beta0 = 39.8+/-5 deg in J2000 ecliptic coordinates, leaving intact the physical solution for ...

Surface Compositions of Trojan Asteroids
Space Science ReviewsAbstractThe Jupiter Trojan asteroids are a key population for understanding the chemical and dynamical evolution of the Solar System. Surface compositions of Trojans, in turn, provide crucial information for reconstructing their histories. NASA’s Lucy mission will soon complete the first spacecraft reconnaissance of this population.
