Abstract

We use nonlinear kinetic theory to study cosmic ray acceleration and the properties of the nonthermal emission from the supernova remnant SN 1006. The known range of astronomical parameters is examined in order to find out whether it encompasses the existing synchrotron emission data. It is shown that the hadronic gamma-ray flux is very sensitive to the ambient gas density N_H and hat the existing H.E.S.S. upper limit requires N_H < 0.1 cm^-3. The amplified magnetic field downstream of the shock amounts to about 150 μG.
