Hydrodynamical Simulations of the Young Supernova Remnant CTB 109 — •Jan Bolte¹, Manami Sasaki², and Dieter Breitschwerdt¹ — ¹Zentrum für Astronomie und Astrophysik, TU Berlin — ²Institut für Astronomie & Astrophysik, Universität Tübingen

Based on the assumption that the background medium has not changed significantly during the evolution of the SNR, we use the present ambient medium, given by the CO emission, as the initial condition of a 3D hydrodynamical simulation. By adding an additional small dense cloud to this realistic inhomogeneous medium, not only the observed morphology of the remnant can be reproduced very well, but also the prominent X-ray lobe of CTB 109 can be explained as the result of a shocked dense cloud. With further constraints from X-ray observations we can derive various important physical parameters from the parameter studies and get a picture of the preshock medium.
