Abstract In this paper we have made a comprehensive statistical study on the Coronal Mass Ejections (CMEs) associated with Prominence Eruptions (PEs). A total number of 576 Prominence Eruptions observed by Nobeyama Radioheliograph during the period January, 1996 to December, 2013. We have studied the distribution of Coronal Mass Ejections speed, angular width and acceleration for Prominence Eruptions associated Coronal Mass Ejections. The median (average) linear speed is 492 (521)km/s. The mean angular width is 77°. The speed of Prominence Eruptions varies from few km/s to 400km/s with the average value 89km/s. Majority of Prominence Eruptions associate Coronal Mass Ejections are accelerating. On studying the speed-acceleration correlation for these events, we found that there is no correlation between them. The number variation during solar cycle of prominence activities is similar to that of sunspots. The fraction of Prominence Eruptions associated Coronal Mass Ejections during the solar minimum is less than that during solar maximum. We have also studied the mass, energy and latitudinal distribution of Prominence Eruptions associated Coronal Mass Ejections.
Highlights 81% PEs have their time duration up-to 90min. Mean and median speed of PEs is 89km/s and 66km/s respectively. The average/median width for CMEs those associated with PEs is 77°/46°. The acceleration distribution shows a conspicuous peak near 10m/s2 with biasing towards acceleration. Rate of PEs and PEs associated CMEs varies with solar cycle.
