Water and astrobiology (2007, background): “The identity of the light element(s) in the inner and outer core, required to explain their density, is a major unsolved problem (McDonough, 2005; Asahara et al., 2007; Badro et al., 2007; Corgne et al., 2007).”
Melting in the Fe–C system to 70 GPa (2009, background): “Several possible contenders have been proposed for the alloying elements, including hydrogen, carbon, oxygen, silicon and sulfur (Poirier, 1994), with the popularity of each waxing and waning, and some mixture seems most likely (e.g. Alfè et al., 2002; McDonough, 2003; Badro et al., 2007).”
Solidus and liquidus profiles of chondritic mantle: Implication for melting of the Earth across its history (2011, background): “And, if the outer core contains a mixture of light elements S, Si and O (Badro et al., 2007; Poirier, 1994), the resulting melting temperature should be lower than measured in binary compounds.”
Composition of the Earth's inner core from high-pressure sound velocity measurements in Fe–Ni–Si alloys (2010, methodology): “…2001; Vočadlo, 40 2007; Morard et al., 2008; Côté et al., 2008a], oxygen [Sherman, 1991; Sherman, 1995;41 Stixrude et al., 1997; Rubie et al., 2004; Badro et al., 2007; Asahara et al., 2007; Corgne et al., 42 2009], and silicon [Sherman, 1997; Dobson et al., 2003; Vočadlo, 2007; Badro et al.,…”
MASS–RADIUS RELATION FOR ROCKY PLANETS BASED ON PREM (2015, background): “The lighter elements could be S, Si, O, C, or a combination of them (Badro et al. 2007; Fischer et al. 2012; Alfè et al. 2002; Poirier 1994; Stixrude et al. 1997; Anderson & Ahrens 1994), but no agreement is reached as to which of these elements are most important.”
Accretion and differentiation of the terrestrial planets with implications for the compositions of early-formed Solar System bodies and accretion of water (2014, background): “However, other sound velocity studies (Badro et al., 2007) and ab initio simulations (Alfè at al., 2002, 2007) have predicted that the outer core contains a significantly higher concentration of O and a lower concentration of Si than the values estimated here.”
