Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
Insight into the Distribution of High-pressure Shock Metamorphism in Rubble-pile Asteroids
Nicole Güldemeister, Juulia-Gabrielle Moreau, Tomas Kohout +2
Shock metamorphism in ordinary chondrites allows for reconstructing impact events between asteroids in the main asteroid belt. Shock-darkening of ordinary chondrites occurs at the…
Sub-surface alteration and related change in reflectance spectra of space-weathered materials
K. Chrbolková, P. Halodová, T. Kohout +7
One of the main complications for the interpretation of reflectance spectra of airless planetary bodies is surface alteration by space weathering caused by irradiation by solar win…
Comparison of space weathering spectral changes induced by solar wind and micrometeoroid impacts using ion- and femtosecond-laser-irradiated olivine and pyroxene
K. Chrbolková, R. Brunetto, J. Ďurech +8
Space weathering is a process that changes the surface of airless planetary bodies. Prime space weathering agents are solar wind irradiation and micrometeoroid bombardment. These p…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
Experimental constraints on the ordinary chondrite shock darkening caused by asteroid collisions
T. Kohout, E. V. Petrova, G. A. Yakovlev +10
Shock-induced changes in ordinary chondrite meteorites related to impacts or planetary collisions are known to be capable of altering their optical properties. Thus, one can hypoth…
Annama H chondrite - mineralogy, physical properties, cosmic ray exposure, and parent body history
Tomáš Kohout, Jakub Haloda, Patricie Halodová +27
The fall of the Annama meteorite occurred early morning (local time) on April 19, 2014 on the Kola Peninsula (Russia). Based on mineralogy and physical properties, Annama is a typi…
Shock-darkening in ordinary chondrites: determination of the pressure-temperature conditions by shock physics mesoscale modeling
J. Moreau, T. Kohout, K. Wünnemann
We determined the shock-darkening pressure range in ordinary chondrites using the iSALE shock physics code. We simulated planar shock waves on a mesoscale in a sample layer at diff…
Orbit and dynamic origin of the recently recovered Annama's H5 chondrite
Josep M. Trigo-Rodriguez, Esko Lyytinen, Maria Gritsevich +7
We describe the fall of Annama meteorite occurred in the remote Kola Peninsula (Russia) close to Finnish border on April 19, 2014 (local time). The fireball was instrumentally obse…
A comprehensive study of distribution laws for the fragments of Košice meteorite
Maria Gritsevich, Vladimir Vinnikov, Tomáš Kohout +4
In this study, we conduct a detailed analysis of the Košice meteorite fall (February 28, 2010), in order to derive a reliable law describing the mass distribution among the recover…
Non-invasive geophysical investigation and thermodynamic analysis of a palsa in Lapland, northwest Finland
Tomáš Kohout, Michał S. Bućko, Kai Rasmus +2
Non-invasive geophysical prospecting and a thermodynamic model were used to examine the structure, depth and lateral extent of the frozen core of a palsa near Lake Peerajärvi, in n…
Mineralogy, reflectance spectra, and physical properties of the Chelyabinsk LL5 chondrite, insight into shock induced changes in asteroid regoliths
Tomas Kohout, Maria Gritsevich, Victor I. Grokhovsky +6
The mineralogy and physical properties of Chelyabinsk meteorites (fall, February 15, 2013) are presented. Three types of meteorite material are present, described as the light-colo…
