Title: CO nucleus outgassing of 29P/Schwassmann-Wachmann 1
Authors: D. Bockelee-Morvan, N. Biver, J. Crovisier, F. Henry  

Abstract: Comet 29P/Schwassmann-Wachmann 1 is an unusual comet 
   which orbits on an almost circular orbit at ~6 AU from the Sun.
   It shows a well developed dusty coma and recurrent outbursts.
   CO is the only detected parent molecule (through millimeter
   observations), and likely one of the main drivers of this activity. 
   Maps of the CO J(2-1) line profiles show that part of the CO 
   is not directly released by the nucleus, but presents a much 
   more extended distribution due to diffuse production in the coma 
   by possibly icy grains or a parent species, like CO2. By filtering 
   the diffuse CO coma, interferometric maps will unravel CO 
   outgassing from the nucleus and the kinematics of the inner coma.
