Internetwork dynamics

Abstract

This review places current research in quiet-Sun chromospheric dynamics in the context of past and future work, concentrating on observational aspects of three-minute oscillations and Ca II K2V grains. The subject is of interest at present because observations and simulations come together to permit detailed understanding of how grains form out of oscillations. Issues that remain are their spatial occurrence characteristics, in particular with respect to internetwork fields and canopies, and their energetics, in particular with respect to the basal ux.
