Abstract:

We present a critical analysis on the number of bursts near 21 cm from nine dMe flare stars of the solar neighborhood as reported in the literature. We compare our findings with the number of bursts detected with the Arecibo radiotelescope between 1989 and 1993, using a very reliable method to discriminate between stellar and artificial emissions. We compare the rates of radio bursts per hour inferred from both this Arecibo campaign and the literature to rates of optical flares found in the literature. We also compare the nine stars to each other, and the Arecibo results to radio surveys of two open clusters.

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.
