Abstract
Ionized radiators and charged perturbers in a hot, dense plasma undergo cyclotron motion and experience the motional Stark effect in the presence of an external magnetic field. In this paper, we consider a magnetized two-body radiating system and indicate how the lineshape can be modified by an intense magnetic field (e.g. non-uniform magnetic fields, Doppler-Stark coupling, etc.) We then focus specifically on quasistatic properties and present results based on simulations, using one-component ion-quasiparticle molecular dynamics, of a hot dense plasma in an external magnetic field. Results are presented for the three generalized microfields p(ϵ), P B(ϵ), and ℘(ϵ) which are the B = 0 microfield, the microfield including ion cyclotron motion, and the total microfield, including the motional Stark field, respectively. We have considered short-pulse laser experiments, white dwarf atmospheres, and gas bag experiments.
