Abstract
X ray emission and activity in late type stars are generally believed to be caused by magnetic fields generated below the stellar photosphere. Coronal magnetic fields should induce structuring of the coronal plasma in loop like structures, as observed in the Sun. Do we have evidence of such structuring? I shall discuss how spectrally resolved X ray observations can evidence the existence of stationary stellar coronal loops. I shall also discuss how the lengths of stellar loops can be inferred by spectrally resolved observations during flare decay, and how the presence of coronal magnetic fields might influence the thermal stability of the transition region and induce characteristics signatures in line profiles.
