A General Spectral Slope-Exposure Relation for S-Type Main Belt and Near-Earth Asteroids [PDF]
The Astronomical Journal, 2006 We present a general and significant relation between the spectral slope of silicate-rich asteroids (both main-belt and near-Earth asteroids) and the exposure to space weathering, computed taking into account the age and the distance from the Sun. We find strong evidence for the existence of a slope-distance relation that may identify the dominant ...

Hybrid simulations of solar wind interaction with magnetized asteroids: General characteristics [PDF]
Journal of Geophysical Research: Space Physics, 2002 Using electromagnetic hybrid (kinetic ions, fluid electrons) simulations, the interaction between solar wind and a magnetized asteroid is investigated. At no or very low levels of asteroid magnetization the solar wind remains undisturbed. As the level of magnetization is increased, a phase standing whistler wake is generated which owing to its ...

Prospects of Dynamical Determination of General Relativity Parameterβand Solar Quadrupole Moment ${J}_{2\odot }$ with Asteroid Radar Astronomy [PDF]
, 2017 We evaluated the prospects of quantifying the parameterized post-Newtonian parameter β and solar quadrupole moment with observations of near-Earth asteroids with large orbital precession rates (9 to 27 arcsec century−1).

Deficit of primitive compositions in binary asteroids and pairs [PDF]
Astronomy & Astrophysics, 2023 Context. Small binary asteroid systems and pairs are thought to form through fission induced by spin up via the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. This process is expected to depend on their structural strength, hence composition. Aims.

The accuracy of mutual potential approximations in simulations of binary asteroids [PDF]
Astronomy & Astrophysics, 2023 Simulations of asteroid binaries commonly use mutual gravitational potentials approximated by series expansions, leading to truncation errors, and also preventing correct computations of the forces and torques when the bodies are close.

A Deep and Wide Twilight Survey for Asteroids Interior to Earth and Venus [PDF]
Astronomical Journal, 2022 We are conducting a survey using twilight time on the Dark Energy Camera with the Blanco 4 m telescope in Chile to look for objects interior to Earth’s and Venus’ orbits. To date we have discovered two rare Atira/Apohele asteroids, 2021 LJ4 and 2021 PH27,

A polarimetric study of asteroids in comet-like orbits [PDF]
Astronomy & Astrophysics, 2021 Context. Asteroids in comet-like orbits (ACOs) consist of asteroids and dormant comets. Due to their similar appearance, it is chal- lenging to distinguish dormant comets from ACOs via general telescopic observations.
