EIT wave observations and modeling in the STEREO era
2011年6月20日 · “EIT waves” are large-scale bright fronts observed propagating in the solar corona in association with coronal mass ejections (CMEs). An overview of the observed properties of large-scale wave-like fronts in the solar atmosphere (Moreton waves, EIT waves and similar phenomena observed in other wavelengths) is presented.
Understanding the Physical Nature of Coronal "EIT Waves"
2016年11月16日 · In this article, we reexamine the theories proposed to explain "EIT waves" to identify measurable properties and behaviours that can be compared to current and future observations. Most of us conclude that "EIT waves" are best described as fast-mode large-amplitude waves/shocks that are initially driven by the impulsive expansion of an erupting ...
[1108.5274] "EIT Waves" and Coronal Mass Ejections - arXiv.org
2011年8月26日 · In this paper, we first summarize all the observational features of "EIT waves", which should be accounted for by any successful model. The theoretical models constructed during the past 10 years are then reviewed. Finally, the implication of the "EIT wave" research to the understanding of CMEs is discussed.
Understanding the Physical Nature of Coronal “EIT Waves”
2021年5月19日 · For almost 20 years the physical nature of globally propagating waves in the solar corona (commonly called “EIT waves”) has been controversial and subject to debate. Additional theories have been proposed over the years to explain observations that did not agree with the originally proposed fast-mode wave interpretation.

Early observations by the EUV Imaging Telescope (EIT) on the Solar and Heliospheric Observatory indicated that propagating diffuse wave fronts, now conventionally referred to as ``EIT waves,'' can often be seen on the solar disk with a propagation velocity several times smaller than that of Hα Moreton waves.

2010年2月21日 · "EIT waves" are a wavelike phenomenon propagating in the corona, which were initially observed in the extreme ultraviolet (EUV) wavelength by the EUV Imaging Telescope (EIT). Their nature is still elusive, with the debate between fast-mode wave model and …

2005年4月1日 · Early observations by the EUV Imaging Telescope (EIT) on the Solar and Heliospheric Observatory indicated that propagating diffuse wave fronts, now conventionally referred to as "EIT waves," can often be seen on the solar disk with a propagation velocity several times smaller than that of Hα Moreton waves. They are almost always associated ...
Intensity dynamics of an “EIT wave” observed by trace
1998年6月13日 · We find the "EIT wave" is observable as a propagating crest for 400-500 seconds before it dissipates and/or is disrupted by in-situ magnetic structures. We examine eight vectors that can be modelled in part by Gaussian curves.
2019年5月27日 · Coronal “Extreme ultraviolet Imaging Telescope (EIT) wave” transients are typically observed as moving fronts of increased coronal EUV emission, traveling at the speeds of a few hun-dred km s−1 (Dere et al. 1997; Thompson et al. 1998, 1999).
Although known colloquially as “EIT waves”—recognizing their initial discovery by the SOHO-EIT instrument (Delaboudiniere et al. 1995)—it is important to note that the label “wave” is purely phenomenological; while in many respects they act like waves, several recent models question this assumption, and put forth alternative theories.
