Chondrite Parent Bodies as Escaped Satellites of Proto-Planetary Embryos
Harold F. Levison, Rogerio Deienno, Kevin J. Walsh +4
Chondrites are composed of formerly partially molten material, known as chondrules, surrounded by fine-grained matrix. They date from the earliest times in Solar System history. Ho…
Tracking the Activity of the Interstellar Object 3I/ATLAS through its Perihelion
T. Marshall Eubanks, Craig E. DeForest, Kevin J. Walsh +10
In order to facilitate interplanetary spacecraft observationsof 3I/ATLAS, we have monitored and predicted the optical properties of its coma using both ground and space-based obser…
Shaking and Tumbling: Short- and Long-Timescale Mechanisms for Resurfacing of Near-Earth Asteroid Surfaces from Planetary Tides and Predictions for the 2029 Earth Encounter by (99942) Apophis
R. -L. Ballouz, H. Agrusa, O. S. Barnouin +14
Spectral characterization of near-Earth asteroids (NEAs) has revealed a continuum of space-weathered states for the surfaces of S-complex NEAs, with Q-class NEAs, an S-complex subc…
Accretion and Uneven Depletion of the Main Asteroid Belt
Rogerio Deienno, David Nesvorny, Matthew S. Clement +3
The main asteroid belt (MAB) is known to be primarily composed of objects from two distinct taxonomic classes, generically defined here as S- and C-complex. The former probably ori…
Tidal disruption of near-Earth asteroids during close encounters with terrestrial planets
Mikael Granvik, Kevin J. Walsh
Numerical modeling has long suggested that gravitationally-bound (or so-called rubble-pile) near-Earth asteroids (NEAs) can be destroyed by tidal forces during close and slow encou…
An efficient numerical approach to modeling the effects of particle shape on rubble-pile dynamics
Julian C. Marohnic, Joseph V. DeMartini, Derek C. Richardson +2
We present an approach for the inclusion of non-spherical constituents in high-resolution N-body discrete element method (DEM) simulations. We use aggregates composed of bonded sph…
SPH/N-body simulations of small (D = 10 km) asteroidal breakups and improved parametric relations for Monte-Carlo collisional models
P. Ševeček, M. Brož, D. Nesvorný +4
We report on our study of asteroidal breakups, i.e. fragmentations of targets, subsequent gravitational reaccumulation and formation of small asteroid families. We focused on paren…
