Description
Summary:The authors present the first high-resolution non-equilibrium ionization simulation of the joint evolution of the Local Bubble (LB) and Loop I superbubbles in the turbulent supernova-driven interstellar medium. The time variation and spatial distribution of the Li-like ions CIV, NV, and OVI inside the LB are studied in detail. This work uses the parallel adaptive mesh refinement code EAF-PAMR coupled to the newly developed atomic and molecular plasma emission module E(A+M)PEC, featuring the time-dependent calculation of the ionization structure of H through Fe, using the latest revision of solar abundances. The finest AMR resolution is 1 pc within a grid that covers a representative patch of the Galactic disk and halo. The evolution age of the LB is derived by the match between the simulated and observed absorption features of the Li-like ions CIV, NV, and OVI.
