X-ray and Microwave Signatures of Coronal Mass Ejections
Abstract
X-ray and microwave imaging of structures associated with coronal mass ejections (CMEs) have provided a wealth of new information towards a better understanding of solar eruptions. I review the recent research based on microwave imaging from the Nobeyama Radioheliograph and X-ray imaging from the Yohkoh Soft X-ray Telescope. I shall discuss the advances made towards understanding the near surface manifestations of CMEs best observed in X-rays and microwaves. In particular, I discuss (i) observability of CMEs in X-rays and microwaves, (ii) coronal dimming, (iii) relation between CME substructures, (iv) heating and expansion of eruptive prominences, (v) timing of flare, CME and prominence eruptions, and (vi) CME mass estimates from non-optical observations.
