Possible thermal and chemical stabilization of body-centred-cubic iron in the Earth's core

Article Abstract:

The authors discuss the nature of the iron in the solid inner core of the Earth. They describe the use of the quantum mechanical study of the body central cubic-iron in order to model its behavior at core temperatures and pressures, and report that the study has been carried out via the use of ab inition molecular dynamics free-energy calculations.

Contemporaneous formation of chondrules and refractory inclusions in the early Solar System

Article Abstract:

The authors have investigated chondrules and calcium-aluminum-rich inclusions which are the preserved materials from the Solar System's early history. The discovery of the chondrule fragment embedded in calcium-aluminum-rich inclusions has suggested that chondrule and calcium-aluminum-rich inclusion formation overlapped in space and time.

The core of planet formation

Article Abstract:

The formation of Earth's metallic core and silcate-based shell is the subject of new high-temperature, high-pressure experiments that show the possibility that highly conductive pathways can be formed in the olivine matrix of the upper mantle. The researchers achieved conditions that simulate 100 km depths on Earth.
