The Evolution of Chromospheric Structure on AR Lacertae

Part of the NATO ASI Series book series (ASIC, volume 319)

Abstract

I present preliminary results from the analysis of a series of ultraviolet spectra AR Lac obtained in 1987. These spectra are being used to image the spatial structure of the chromosphere and to study the dynamics of flaring regions. Comparing these results with previous results, I will discuss the evolution of the chromospheric structure from 1983 to 1987.
