The high conductivity of iron and thermal evolution of the Earth’s core (2013, background): “c is the assumed constant Grüneisen parameter (Vočadlo et al., 2003).”
Thermal evolution of the core with a high thermal conductivity (2014, unknown): “…assumed isentropic, is obtained using (eg Poirier, 2000; Ricard, 2007; Hernlund and Labrosse, 2007) where the integration is performed assuming a constant Gr¨uneisen parameter γ (Alf`e et al., 2001; Voˇcadlo et al., 2003) and T c and ρ c are the temperature and density at the ICB, respectively.”
Thermodynamics, structure, dynamics, and freezing of Mg2SiO4 liquid at high pressure (2008, background): “Gru ¨ neisen parameter decreases with compression (Fig. 3). This behavior was first recognized in silicate liquids by Stixrude and Karki (2005), and has also been found in studies of non-silicate liquids (Davis and Gordon, 1967; Knopoff and Shapiro, 1970; Boehler and Kennedy, 1977; Vocadlo et al., ”
Thermodynamics of silicate liquids in the deep Earth (Invited) (2009, background): “The Grüneisen parameter had previously been found to increase on compression in non-silicate liquids (Boehler and Ramakrishnan, 1980; Knopoff and Shapiro, 1970; Vocadlo et al., 2003).”
