M 3 10 4 M yr 1 in 2001. The rapid increase of the mass loss of IRC+10 216 and continuing time-dependent dust formation and destruction caused the observed displacement of the initially faint components C and D and of the bright cavity A from the star which has almost disappeared in our images in 2001. Increasing dust optical depths are causing strong backwarming that leads to higher temperatures in the dust formation zone, displacing the latter outward with a velocityvT 27 km s 1 due to the…
