Abstract
We present a search for  12CO and SiO emission in V838 Mon. We derive upper limits on the 12CO and SiO emission, and on the total mass of the circumstellar material. Using an excitation temperature of 1000 K, and a likely distance of 6 kpc, the non-detection of 12CO emission leads to a 3 $\sigma$ upper limit on the mass of gas around the central star to be 10 -2  $M_{\odot}$.


Key words: stars: circumstellar matter -- stars: individual: V838 Mon

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.
