Origin of α-poor Very Metal-poor Stars

The Astrophysical Journal
Among very metal-poor (VMP) stars, α -poor VMP ( α -PVMP) stars that have subsolar values of [X/Fe] for Mg and other α elements are rare and are thought to have been formed from gas polluted by Type 1a supernova (SN 1a). However, recent analyses indicate

Statistical Methods for Interpreting Spatial and Temporal Heterogeneity of Martian Tropical Water Ice Informed by Properties of Crater Ejecta Types

Earth and Space Science
The martian tropical water ice spatial and temporal distribution was characterized using impact crater ejecta type, location, size, and age in one of two epochs, ≤3.4 Ga and >3.4 Ga, using statistical models designed for spatial and temporal correlation ...

Contemporaneous formation of self-secondaries and layered ejecta deposits on Mars

Communications Earth & Environment
Self-secondaries are secondary craters formed in cogenetic ejecta deposits. Bearing important information on cratering mechanics and the applicability of remote age-determination technique using crater statistics, the spatial distribution of self ...
