Tables of Planetary Core Radii and Underlying Parameters
<p>This document provides supplementary information, especially numerical values, to the paper "Planetary Core Radii: From Plato towards PLATO" by Knapmeyer & Walterová, to appear in vol. 63 of <em>Advances in Geophysics</em>. That paper investigates the history of core radius determinations for Earth, Moon and Mars since the Renaissance (with some discussion of antique theories). It shows the evolution of published values, but, to save space, does not give numerical tables of the plotted data. All this data, and additional information and discussions, are provided in the present document.</p>
Planetary core-style rotating convective flows in paraboloidal laboratory experiments
<p><span>Turbulent convection in a planet's outer core is simulated here using a thermally-driven free surface paraboloidal laboratory annulus. We show that the rapidly rotating convection dynamics in free-surface paraboloidal annuli are similar to those in planetary spherical shell geometries. Three experimental cases are carried out, respectively, at 35 revolutions per minute (rpm), 50 rpm and 60 rpm.Thermal Rossby waves are detected in full</span><span> disk thermographic images of the fluid's free surface.</span> <span>Ultrasonic flow velocity measurements reveal the presence of multiple azimuthal (zonal) jets, with successively more jets</span><span> forming in higher rotation rate cases.</span> <span>The jets' cylindrical radial extent is well ap</span><span>proximated by the Rhines scale.</span> <span>Over time, the zonal jets migrate to larger radial po</span><span>sition with migration rates in good agreement with prior theoretical estimates.</span> <span>Our re</span><span>sults suggest that planetary core rotating convection will be comprised of flow structures found</span><span> in other turbulent geophysical fluid dynamical systems:</span> <span>convective turbulence dom</span><span>inates the small-scale flow field, and also act to flux energy into larger-scale, slowly evolv</span><span>ing zonal flow structures.</span> <span>How the ambient magnetic fields in planetary core settings af</span><span>fect such turbulent flows remains an open question.</span></p>

Iron Bonding with Light Elements: Implications for Planetary Cores Beyond the Binary System
<p>X-ray Absorption Spectroscopy and DFT calculation dataset for Iron alloys at high pressures. <br><br></p> <p><strong>Abstract: </strong>Light element alloying in iron is required to explain density deficit and seismic wave velocities in Earth’s core. However, the light element composition of the Earth’s core seems hard to constrain as nearly all light element alloying would reduce the density and sound velocity (elastic moduli). The alloying light elements include oxidizing elements like oxygen and sulfur, and reducing elements like hydrogen and carbon, yet their chemical effects in alloy system are less discussed. Moreover, Fe-X-ray Absorption Near Edge Structure (Fe-XANES) fingerprints have been studied for silicate materials with ferrous and ferric ions, while not many X-ray absorption spectroscopy (XAS) studies have focused on iron alloys, especially at high pressures. To investigate the bonding nature of iron alloys in planetary interiors, we presented X-ray absorption spectroscopy of iron-nitrogen and iron-carbon alloys at high pressure up to 50 GPa. Together with existing literature on iron-carbon, -hydrogen alloys, we analyzed their edge positions and found no significant difference of degree of oxidation among these alloys. Pressure effects on edge positions were also found negligible. Our theoretical simulation of the valence state of iron, alloyed with S, C, O, N, P also showed nearly unchanged behavior under pressures up to 300 GPa. This indicates the high pressure bonding of iron alloyed with light elements closely resembles bonding at the ambient conditions. We suggest that the chemical properties of light elements constrain which ones can coexist within iron alloys.<span> </span></p>
