Mineralogy and Surface Composition of Asteroids [PDF]

, 2015
Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade with advancement in laboratory spectral calibrations and validation of our interpretive methodologies by spacecraft rendezvous missions ...

Collisional evolution and reddening of asteroid surfaces - I. The problem of conflicting time-scales and the role of size-dependent effects [PDF]

, 2012
Space weathering is the generic term used for processes that modify the optical properties of surfaces of atmosphereless rocky bodies under exposure to the space environment. The general agreement about the relevance of the effects of space weathering on

Scaling forces to asteroid surfaces: The role of cohesion [PDF]

Icarus, 2010
The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid ...

Candidate Main-belt Asteroids for Surface Heterogeneity [PDF]

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.

Periodic Motion near the Surface of Asteroids [PDF]

Astrophysics and Space Science 2015, 2015
We are interested in the periodic motion and bifurcations near the surface of an asteroid. The gravity field of an irregular asteroid and the equation of motion of a particle near the surface of an asteroid are studied. The periodic motions around the major body of triple asteroid 216 Kleopatra and the OSIRIS REx mission target asteroid 101955 Bennu ...

Optical spectropolarimetry of large C-complex asteroids: polarimetric evidence for heterogeneous surface compositions [PDF]

A&A 677, A146 (2023), 2023
This study presents the first optical spectropolarimetric study of large C-complex asteroids. A total of 64 C-complex asteroids of different subclasses are analyzed using archival polarimetric and reflectance data to refine the link between polarimetric parameters and surface properties of the asteroids.

The Heterogeneous Surface of Asteroid (16) Psyche [PDF]

Journal of Geophysical Research: Planets, 2022
AbstractMain‐belt asteroid (16) Psyche is the largest M‐type asteroid, a class of object classically thought to be the metal cores of differentiated planetesimals and the parent bodies of the iron meteorites. de Kleer, Cambioni, and Shepard (2021, https://doi.org/10.3847/psj/ac01ec) presented new data from the Atacama Large Millimeter Array (ALMA ...

Poincaré surfaces of section around a 3D irregular body: the case of asteroid 4179 Toutatis [PDF]

, 2017
In general, small bodies of the solar system, e.g., asteroids and comets, have a very irregular shape. This feature affects significantly the gravitational potential around these irregular bodies, which hinders dynamical studies.

Compositional Diversity Among Primitive Asteroids [PDF]

, 2018
Spectroscopic observations from the ultraviolet to the mid-infrared have revealed new and diagnostic differences among primitive asteroids. We review the spectral characteristics of these asteroids and their inferred compositional and physical properties.
