Survey of high-altitude partially erupting prominences
Abstract
Solar prominences exhibit a range of eruptive-like dynamic activity, including in some cases the confined or 'failed' ejection of prominence material from the solar atmosphere. Many prominences exhibit a partial eruption in which some mass escapes while the remaining mass drains back to the photosphere. This process may involve the formation of an X-type neutral line in this region, which allows disconnection of part of the prominence material. In a previous study (Gilbert et al. 2000) it was found that this separation tends to occur in the height range from 1.20 to 1.35 Rsun. More recently, the separation point in these types of partial eruptions has been observed to occur at much larger heights. We investigate a selection of these higher partial eruptions, exploring the characteristics of the prominences and their associated CMEs to better understand the dynamical processes in the solar atmosphere associated with eruption.
