Glycine amino acid transformation under impacts by small solar system bodies, simulated via high-pressure torsion method [PDF]

open access: goldScientific Reports, 2022
Impacts by small solar system bodies (meteoroids, asteroids, comets and transitional objects) are characterized by a combination of energy dynamics and chemical modification on both terrestrial and small solar system bodies.

Constraints on the Gamma-Ray Emission from Small Solar System Bodies with the Fermi Large Area Telescope Data [PDF]

open access: greenThe Astrophysical Journal, 2023
All known small solar system bodies have diameters between a few meters and a few thousands of kilometers. Based on the collisional evolution of solar system bodies, a larger number of asteroids with diameters down to ∼2 m is thought to exist.

Performing Automated, High-Speed Photometry on Occulting, Small Outer Solar System Bodies

open access: diamondEdinburgh Student Journal of Science
Monitoring stellar occultations provides a powerful means to measure the shapes and sizes of small Solar System bodies, but produces large quantities of image data which can be laborious to analyse.

A 3‐D Shape Reconstruction Strategy for Small Solar System Bodies With Single Flyby Spaceborne Radar [PDF]

open access: goldEarth and Space Science, 2023
This article presents a novel 3‐D shape reconstruction strategy for small solar system bodies using spaceborne radar which is applied in flyby trajectories to characterize multiple targets in one mission to save time and cost. In this study, we establish

Physical Properties of the Asteroid Belts from Brightness-limited Surveys

open access: yesThe Planetary Science Journal, 2023
We introduce a general debiasing Bayesian formalism to brightness-limited surveys of solar system objects that constrains the statistical distribution of a population’s physical characteristics such as size, albedo, heliocentric distance, or others to ...

What If Planet Nine Has Satellites?

open access: yesThe Astrophysical Journal, 2023
In the past decade, numerical simulations started to reveal the possible existence of Planet Nine in our solar system. The Planet Nine scenario can provide an excellent explanation for the clustering in orbital elements for Kuiper Belt objects.

Observation of Vertically Ejected Plumes Generated by the Impact of Hollow Projectiles at Various Velocities

open access: yesThe Planetary Science Journal, 2023
Recently, impact experiments in space have been conducted in planetary exploration using hollow or internally structured projectiles. In laboratory experiments using hollow projectiles to investigate the differences in crater and ejecta from the case of ...

Methodology for the Observations of Stellar Occultations by Small Bodies of the Solar System

open access: yesJournal of Astronomy and Space Sciences, 2021
The observation of stellar occultations constitutes one of the most important techniques for determining the dimensions and establishing the physical parameters of small Solar System bodies.
