An experimental study of trace element partitioning into troilite during iron meteorite crystallization

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 5, Page 1048-1062, May 2025.
Abstract Troilite is a common phase in iron meteorites, but there are limited data available for the partitioning behavior of elements between troilite and solid metal. In this study, we present the results of experiments with coexisting Fe‐Ni solid metal, an S‐rich metallic liquid, and troilite, conducted at 800–925°C in evacuated silica tubes at 1 ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Longtermism and aggregation

open access: yesPhilosophy and Phenomenological Research, Volume 110, Issue 3, Page 1137-1151, May 2025.
Abstract Advocates of longtermism point out that interventions which focus on improving the prospects of people in the very far future will, in expectation, bring about an astronomical amount of good (or agent‐neutral value). As such, longtermists claim we have compelling moral reason to engage in long‐term interventions.
