Abstract We explore the effects of collisional evolution on putative Vulcanoid ensembles in the region between 0.06 and 0.21 AU from the Sun in order to constrain the probable population density and population structure of this region today. Dynamical studies have shown that the Vulcanoid Zone (VZ) could be populated. However, we find that the frequency and energetics of collisional evolution this close to the Sun, coupled with the efficient radiation transport of small debris out of this…

Structure of possible long-lived asteroid belts
High-resolution simulations are used to map out the detailed structure of two long-lived stable belts of asteroid orbits in the inner Solar system. The Vulcanoid belt extends from 0.09 to 0.20 au,
The inner solar system cratering record and the evolution of impactor populations
We review previously published and newly obtained crater size-frequency distributions in the inner solar system. These data indicate that the Moon and the terrestrial planets have been bombarded by
Evolution of Mercury-like orbits: A numerical study
The orbital evolution of ~$30\,000$ objects has been studied numerically for time scales of up to 11 Myr in order to investigate the dynamical importance of Mercury on objects with orbits similar to
A New Observational Search for Vulcanoids in SOHO/LASCO Coronagraph Images
Abstract We examined SOHO/LASCO (Solar and Heliospheric Observatory/Large Angle Spectroscopic Coronagraph) C3 coronagraph images to search for the long-suspected population of small bodies, the
Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered so
How to design a planetary system for different scattering outcomes: giant impact sweet spot, maximising exocomets, scattered disks
This paper considers the dynamics of scattering of planetesimals or planetary embryos by a planet on a circumstellar orbit. We classify six regions in the planet's mass versus semimajor axis
Testing general relativity with the BepiColombo radio science experiment
The ESA mission BepiColombo will explore the planet Mercury with equipment allowing an extremely accurate tracking. While determining its orbit around Mercury, it will be possible to indirectly
An attempt to detect Vulcanoids with SOHO/LASCO images. I. Scale relativity and quantization of the solar system
We report an attempt to verify one of the predictions of Scale Relativity theory, namely that a small Vulcanoid should exist at 0.18 AU from the Sun. We have analyzed images taken by the coronograph
