“…As these waves are ubiquitous in the partially ionized solar atmosphere, understanding the influence of partial ionization on MHD waves is a key topic of this issue. To lead this area, the review article by Soler [ 4 ] provides a comprehensive overview of the current understanding of the field. Ballester et al [ 5 ] studied the coupling of nonlinear Alfvén waves to thermodynamics in partially ionized plasma finding a complex interplay of damping mechanisms for the waves.…”
