Sonification of Planetary Orbits in Asteroid Belts [PDF]
Audio Mostly 2021, 2021 This study investigates the design and evaluation of a sonification designed to detect any planets orbiting within an asteroid belt of an exosolar system. The interface was designed for an astronomer who studies this phenomenon. User centered design methods were applied to create an accurate sonification of the data that could allow the astronomer to ...

Olivine-rich achondrites from Vesta and the missing mantle problem
Nature Communications, 2021 Ultramafic olivine-rich achondrites provide insight into the missing mantle problem in the asteroid belt. The petrology and geochemistry of these samples suggests they are related to Vesta or the Vestoids.

Mirror formation control in the vicinity of an asteroid [PDF]
, 2008 Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

Planets in the asteroid belt [PDF]
Meteoritics & Planetary Science, 2001 Abstract— The main asteroid belt has lost >99.9% of its solid mass since the time at which the planets were forming, according to models for the protoplanetary nebula. Here we show that the primordial asteroid belt could have been cleared efficiently if much of the original mass accreted to form planetsized bodies, which were capable of perturbing ...

Organic matter and water from asteroid Itokawa
Scientific Reports, 2021 Understanding the true nature of extra-terrestrial water and organic matter that were present at the birth of our solar system, and their subsequent evolution, necessitates the study of pristine astromaterials.

Survey of secular resonances in the asteroid belt [PDF]
Serbian Astronomical Journal, 2022 Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.

Asteroid belt multiple flyby options for M-Class Missions [PDF]
, 2016 Addressing many of the fundamental questions in modern planetary science, as well as in ESA’s cosmic vision, requires a comprehensive knowledge of our Solar System’s asteroid belt. This paper investigates potential opportunities for medium-class asteroid

Ryugu’s Anhydrous Ingredients and Their Spectral Link to Primitive Dust from the Outer Solar System
The Astrophysical Journal Letters, 2023 Ryugu is a second-generation C-type asteroid formed by the reassembly of fragments of a previous larger body in the main asteroid belt. While the majority of Ryugu samples returned by Hayabusa2 are composed of a lithology dominated by aqueously altered ...

ACCURACY OF MYKOLAIV ASTEROID OBSERVATIONS WITH DIFFERENT REFERENCE CATALOGUES
Odessa Astronomical Publications, 2017 The results of astrometric reductions of main belt asteroid observations with usage of 3 different reference catalogues are presented. The high precision catalogs CMC15, UCAC4 and GAIA DR1 were used as reference catalogues for calculation
