Earth’s outer core is liquid and dominantly composed of iron and nickel (~5–10 wt%). Its density, however, is ~8% lower than that of liquid iron, and requires the presence of a significant amount of light element(s). A good way to specify the light
Although further considerations are needed to define the chemical composition of the core, a combination of silicon and oxygen as the light elements in the outer core may be essential and plausible. In the case of a Si-rich outer core, its relatively cool geotherm at the CMB implies that ...
Light elements in the Earth's outer core: A critical review There is little doubt that densities for the Earth's outer core, inferred from seismology, require that it is constituted of an alloy of liquid iron and li... JP Poirier - 《Physics of the Earth & Planetary Interiors》 被引量...
spends 90% of its lifetime fusing hydrogen into helium. After the hydrogen has been depleted, it begins fusing helium into higher elements. With each new stage of elemental fusion, the core becomes denser, and the outer layers of the stars begin to expand, gradually turning into a red ...
This involved improvements in stellar models, the composition of stellar wind ejecta, the mechanism of core-collapse supernovae as final fate of massive stars, and the transition (as a function of initial stellar mass) from core-collapse supernovae to hypernovae and long duration gamma-ray ...

(average 4.81%). Quantitative analysis of elements shows that the distribution pattern of major elements in core follows SiO2>Al2O3>Fe2O3>Na2O>K2O>MgO>CaO>TiO2>P2O5>MnO. Clearly, the most abundant major element is Si, coming mainly from terrigenous debris (quartz) and siliceous biogenic ...

Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated. Here we discuss the processes that distributed th
