Abstract:

We compare the coronal transient wave phenomenon discovered by SOHO extreme ultraviolet observations ("EIT waves'') with the associated radio signature of a coronal shock wave (type II burst). 90% of the type II bursts are associated with an EIT wave. On average, the speed derived from the radio burst is about three times larger than the EIT wave speed. Within the sample, there is no correlation between the speeds of both tracers of a coronal disturbance. Under very general assumptions we conclude that both wave phenomena can be different signatures of the same fast magnetosonic disturbance.

Key words: Sun: corona -- flares -- radio radiation -- shock waves

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
