Hyperfine splitting of [Al VI] 3.66 mu m and the Al isotopic ratio in NGC 6302
The core of planetary nebula NGC 6302 is filled with high-excitation photoionized gas at low expansion velocities. It represents a unique astrophysical situation in which to search for hyperfine structure (HFS) in coronal emission lines from highly ionized species. HFS is otherwise blended by therma...
