Small bodies in the Solar System
- Anna Losiak (Institute of Geological Sciences Polish Academy of Sciences)
Although ordinary chondrites are stony meteorites they still contain significant amount of metals (up to 18.6wt%), mainly occurring as FeNi alloy grains. This makes ordinary chondrites and their parent rocks very important in extra-terrestrial metallic resource considerations, crucial for ISRU concept (In Situ Resource Utilization). S-type asteroids both belonging to Near Earth Asteroids...
A group of Polish physicists and mineralogists has been studying meteorites using Mössbauer spectroscopy for over 30 years [1].
Since Fe-57 is the isotope commonly used in Mössbauer spectroscopy, it is not surprising that this method is widely applied in the study of meteorites that often contain iron. For many years, our group has focused on ordinary chondrites. The Mössbauer spectra of...
Modeling the internal structure of self-gravitating solid and liquid bodies presents a challenge, as existing approaches are often limited to either overly simplistic constant-density approximations or more complex numerical equations of state. We present a detailed analysis of a tractable and physically motivated model for perfectly elastic, spherically symmetric self-gravitating bodies in...
Proximal ejecta blankets of very small (<200 m in diameter) impact craters can contain fragments of charcoal (Losiak et al. 2022). Those charcoals can be used to: precisely and accurately date impact structures, determine environmental effects of impacts of small asteroids, and potentially, better understand the energy distribution during formation of very small impact craters or identify...
Meteorites that have impacted the Earth's surface in the past have created impact craters. Most of these craters have not been preserved in a form that allows for their contemporary identification, but some, especially in Central and Northern Europe, have been described and classified as geological structures formed by meteorite impacts. When a celestial body strikes the Earth's surface, it...
