Abstract
We present here a proposal for the mid-infrared study
of the circumstellar material around Z CMa. The suggested configuration of
the interferometer and the observational strategy
are based on model simulations performed using the software ASPRO.
We find that the UT1-UT3 telescope pair (the first mode to be offered)
is able to constrain the flux ratio of the binary but not the
extension of possible circumbinary disks.
We suggest to use an AT unit to increase the baseline and thus
resolve the material orbiting one or two components.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle 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.
