The stellar origins of 96Zr excesses in presolar graphites from the Murchison meteorite

Astronomy & Astrophysics
Context. Zirconium-96 is a stable isotope that can be synthesized under different neutron-rich nucleosynthetic conditions. Astrophysical models predict its production to occur in various stellar environments: from low-to-intermediate-mass asymptotic ...

Potassium isotopic compositions and exposure ages of evolved and silica‐rich achondrites

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2140-2162, August 2026.
Abstract Some of the oldest igneous rocks in the Solar System include evolved and silica‐rich achondrites that originate from parent bodies less than 1000 km in diameter, referred to as planetesimals. While Earth was initially in a molten state and required continental crust formation and plate tectonics to generate andesite bulk compositions, evolved ...

Coupling dynamical accretion and chemical differentiation: A unified framework for the diversity of Earth and Mars

Astronomy & Astrophysics
The physical and geochemical differences between Earth and Mars provide fundamental constraints on terrestrial planet formation, yet a self-consistent framework linking dynamical and chemical aspects remains elusive.

Exogenous carbonaceous material on Phobos

Astronomy & Astrophysics
Aims. We analyze Mars Express (MeX)/OMEGA Phobos’ data in the 2.5–3.9 μm range to investigate the presence of organic material. Methods. We applied a thermal correction to the OMEGA data and identified regions of interest (ROIs) to extract mean spectra ...

Densities and porosities of meteoroids

, 2008
Using a physical theory of meteors and on the basis of the results of double-station photographic observations of meteors in Dushanbe (Tajikistan), Kiev, and Odessa (Ukraine), the mean mineralogical and bulk densities of meteoroids belonging to nine ...
