Project description
Proxies of Earth’s and Mars’ building blocks point to their sources
Certain types of meteorites contain the first solid material to form in our solar system during planetary accretion. Nucleosynthetic anomalies – small variations in isotope abundance of their constituents – tell scientists about the environment in which the materials were created and the potential building blocks of planets. With the support of the Marie Skłodowska-Curie Actions programme, the NuKleOrigin project aims to determine the source of recently identified nucleosynthetic anomalies in the moderately volatile elements potassium and zinc (elements that condense or solidify at low temperatures) as proxies for more volatile elements (carbon, nitrogen and oxygen) on the trail towards deciphering the building blocks of Earth and Mars.
Objective
The Solar System has long been thought to represent the only habitable planetary system. The discovery that planets orbiting Sun-like stars are common in our Galaxy has fostered the concept of planetary habitability, which defines the conditions at the surface of a planet required for life to develop, including the presence of volatiles, energy, and organic chemistry. Elucidating the relationship between the formation pathways of rocky planets and their potential habitability is crucial in that regard.
One way to approach this is to determine the origin and composition of the building blocks of planets. Meteorites are witnesses of the earliest stages of planetary accretion and are ideal for this task. Nucleosynthetic anomalies (which are mass-independent variations of the isotope composition) measured in meteorites provide insights into the building blocks of planets. They are robust tracers because they are not affected by geodynamic and chemical differentiation of the planets. However, the determination of the building blocks of planets necessitates to consider a holistic approach considering constraints from elements with different volatility and cosmochemical behaviour in all extra-terrestrial materials. For instance, nucleosynthetic anomalies of refractory lithophile and siderophile elements do not provide precise constraints on the origin of volatile elements in planets.
The very recent identification of nucleosynthetic anomalies in moderately volatile elements K and Zn opens new avenues of research as robust proxies of more volatile elements. This project aims at determining the source of the nucleosynthetic anomalies of moderately volatile elements and defining the building blocks of Earth and Mars building blocks and the source of volatile elements. I will use next generation instrumentation combined with emerging technologies to carry out this project.
