Abstract
In this paper we present giant planetary companions to the stars HD 28185 and HD 213240 . Both candidates were discovered in the context of the CORALIE extra-solar planet search programme. The planet around HD 28185 , with a minimum mass of 5.7 M_Jup is one of the first long period planets (P=383 days) discovered so far orbiting its host star in a nearly circular trajectory. On the other hand, the planet around HD 213240 , with a 951-day period orbit, an eccentricity of 0.45, and a minimum mass of 4.5 M_Jup, is more typical of the up to now discovered long period systems.

Key words: planetary systems -- stars: individual: HD 28185 -- stars: individual: HD 213240

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.
