Main-belt Asteroids in the K2 Uranus Field [PDF]
The Astrophysical Journal Supplement Series, 2018 Abstract We present the K2 light curves of a large sample of untargeted main-belt asteroids (MBAs) detected with the Kepler Space Telescope. The asteroids were observed within the Uranus superstamp, a relatively large, continuous field with a low stellar background designed to cover the planet Uranus and its moons during Campaign 8 of ...

Ryugu’s observed volatile loss did not arise from impact heating alone
Communications Earth & Environment, 2021 The loss of volatile material from asteroid Ryugu was not caused solely by heating from hypervelocity impacts as previously believed, suggest impact experiments conducted at speeds comparable to those expected in the main asteroid ...

Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
The Planetary Science Journal, 2022 Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes ...

On nature of evolution of short-period comets. On the question of short-period comets evolution
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 The main hypothesis of short-period comets evolution are considered. Basing on the performed researches we conclude that the main sources of short-period comets are: main asteroid belt, relict asteroid belts between giant planets and the Kuiper belt.

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.
