> **Every charge drifts at \(v_r=-E_z B_\theta/B^2\). At \(3000\)–\(6000\,\mathrm{K}\) and \(n_H=10^{14}\)–\(10^{16}\,\mathrm{m^{-3}}\), Fe, Mg, Si, Ni, and Ca have \(x\ge 0.91\). Hydrogen runs from about \(5\times 10^{-9}\) to \(0.98\). Helium stays at or below \(10^{-7}\). The band \(0.2\)–\(0.3\,R\) is \(Z^{1/3}\) of a uniform sphere. The core seat stays closed.**

For \(Z=0.0134\) the equal-density radius is \(0.238\,R\) in a sphere and \(0.116\,R\) in a cylinder. The helioseismic convection-zone base is \(0.713\,R_\odot\). No drift integral is on this page. Resume of an interior flow remains the six-gate atmosphere filament. No ledger row. No promote.
