MHD波和日冕地震学:最近结果综述

MHD Waves and Coronal Seismology: an overview of recent results

Ineke De Moortel, Valery M. Nakariakov

摘要:

最近的观测表明,MHD波和振荡普遍存在于太阳大气中,具有广泛的周期。本文对最近引起激烈争论或正在兴起的磁流体波和日冕地震学的某些方面作了简要的评述。特别是,我们专注于四个主题:(一)目前的争议传播强度扰动沿日冕环,(二)传播横向环振荡的解释,(三)正在进行的搜索日冕(扭转)阿尔芬波和(四)迅速发展的准周期脉动(QPP)在太阳耀斑的主题。

英文摘要:

Recent observations have revealed that MHD waves and oscillations are ubiquitous in the solar atmosphere, with a wide range of periods. We give a brief review of some aspects of MHD waves and coronal seismology which have recently been the focus of intense debate or are newly emerging. In particular, we focus on four topics: (i) the current controversy surrounding propagating intensity perturbations along coronal loops, (ii) the interpretation of propagating transverse loop oscillations, (iii) the ongoing search for coronal (torsional) Alfven waves and (iv) the rapidly developing topic of quasi-periodic pulsations (QPP) in solar flares.
