Spectral evolution of an eruptive polar crown prominence with IRIS observations

Li, Hui; Su, Yang; Xue, Jianchao

Prominence eruption is closely related to coronal mass ejections and is an important topic in solar physics. Spectroscopic observation is an effective way to explore the plasma properties, but the spectral observations of eruptive prominences are rare. In this paper we will introduce an eruptive polar crown prominence with spectral observations fr…
