Hybrid simulations of solar wind interaction with magnetized asteroids: General characteristics [PDF]

open access: bronzeJournal 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 ...

DreamSat-2.0: Towards a General Single-View Asteroid 3D Reconstruction [PDF]

open access: green
To enhance asteroid exploration and autonomous spacecraft navigation, we introduce DreamSat-2.0, a pipeline that benchmarks three state-of-the-art 3D reconstruction models-Hunyuan-3D, Trellis-3D, and Ouroboros-3D-on custom spacecraft and asteroid datasets.

Transmission of a Seismic Wave Generated by Impacts on Granular Asteroids

open access: yesThe Planetary Science Journal, 2022
Abstract In this paper, we use a soft-sphere discrete element method code to simulate the transmission and study the attenuation of a seismic wave. Then, we apply our findings to the different space missions that have had to touch the surface of different small bodies in the solar system.

Unbiased orbit determination for the next generation asteroid/comet surveys [PDF]

open access: yesProceedings of the International Astronomical Union, 2005
In the next generation surveys, the discovery of moving objects can be successful only if an observation strategy and the identication/orbit determination procedure are appropriate for the diverse apparent motions of the target sub-populations. The observations must accurately measure the displacement over a short interval of time; observations ...

Tsunami generation and propagation from the Mjølnir asteroid impact [PDF]

open access: yesMeteoritics & Planetary Science, 2007
Abstract— In the late Jurassic period, about 142 million years ago, an asteroid hit the shallow paleo‐Barents Sea, north of present‐day Norway. The geological structure resulting from the impact is today known as the Mjølnir crater. The present work attempts to model the generation and the propagation of the tsunami from the Mjølnir impact.

Asteroid-Generated Tsunamis: A Review

open access: yes, 2022
AbstractWe study ocean waves caused by an asteroid airburst located over the ocean. The concern is that the waves would damage distant coastal cities. Simple qualitative analysis suggests that the wave energy is proportional to the ocean depth and the strength and speed of the blast.

Large main-belt asteroids are generally not Maclaurin or Jacobi ellipsoids

open access: yesAstronomy & Astrophysics, 2023
Aims.A recent major high-angular-resolution imaging survey of 42 large main-belt asteroids (D > 100 km) with VLT/SPHERE has provided shape models of these bodies with an unprecedented accuracy. We ask whether the shapes of these bodies correspond to Maclaurin or Jacobi hydrostatic equilibrium figures.Methods.To address this question, we compared the
