Collisional Evolution in the Vulcanoid Region: Implications for Present-Day Population Constraints

  title={Collisional Evolution in the Vulcanoid Region: Implications for Present-Day Population Constraints},
  author={S. Alan Stern and Daniel D. Durda},
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…

The Vulcanoid Asteroids: Past, Present and Future
A review and discussion of both the historical and contemporaneous ideas pertaining to the putative population of Vulcanoid asteroids is presented. Current observations indicate that no objects
The Depletion of the Putative Vulcanoid Population via the Yarkovsky Effect
Abstract The geophysical history of Mercury is constrained by its crater record, its tectonics, and its magnetic field. Standard thermal models based on these constraints lead to inconsistent results
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
Vulcanoid Asteroids and Sun-Grazing Comets – Past Encounters and Possible Outcomes
The region between 0.07 to 0.25 au from the Sun is regularly crossed by sungrazing and small perihelion distance periodic comets. This zone also supports stable orbits that may be occupied by
Understanding the evolution of Atira-class asteroid 2019 AQ3, a major step towards the future discovery of the Vatira population
Orbiting the Sun at an average distance of 0.59 au and with the shortest aphelion of any known minor body, at 0.77 au, the Atira-class asteroid 2019 AQ3 may be an orbital outlier or perhaps an
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

Collisional Time Scales in the Kuiper Disk and Their Implications
We explore the rate of collisions among bodies in the present-day Kuiper Disk as a function of the total mass and population size structure of the disk. We find that collisional evolution is an

Abstract Collision cascades play a prominent role in processing the present asteroid belt, as well as formative planetary systems. As a first step toward understanding how this mechanism operates, an

Abstract We provide a unified discussion of the Yarkovsky effect in both the original, “diurnal” variant and also for the “seasonal” variant which has been recently shown by Rubincam (1995) to be
