DOIAbstract
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 3σ upper limit on the mass of gas around the central star to be 10-2 $M_{\odot}$.
