Abstract
We have imaged at high angular resolution the close environement of the very red source Orion n with NACO at the VLT UT4. We report the detection of a faint point like object  0.6'' away from this source. Assuming a distance of  450-50+50 pc and an age of 1 Myr, the photometry of this candidate companion is consistent with an object of mass 70-150  $M_{\rm {J}}$ assuming a visible extinction of  $A_{\rm {V}} = 3{-}17$. The relationship between this object and Orion n is discussed hereafter.


Key words: stars: formation -- stars: low-mass, brown dwarfs -- stars: pre-main sequence

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.
