Plasma/dust Torus around Luhman 16A (fictional)

Surn’s intense tidal volcanism ejects large amounts of carbon-rich particles (amorphous carbon, graphite dust, and carbides) into space. Once ejected, these particles become electrostatically charged and are trapped within Luhman 16A’s magnetosphere, forming a toroidal dust-and-plasma structure along Surn’s orbit.

Unlike Io’s plasma torus, which is primarily detected in the UV, Surn’s contribution of carbon dust increases the optical scattering cross-section of the torus. This allows the structure to reflect and scatter a measurable fraction of incoming radiation from Luhman 16A. As a result, the torus becomes faintly visible, appearing as a dim, diffuse dusty band encircling the brown dwarf.
