Abstract: We present computational results showing eccentricity growth in the innerportions of a protoplanetary disc. We attribute this to the evolving surfacedensity of the disc. The planet creates a gap, which adjusts the balancebetween the 3:1 eccentricity exciting and 2:1 eccentricity dampingresonances. The eccentricity of the inner disc can rise as high as 0.3, whichis sufficient to cause it to be accreted onto the star. This offers analternative mechanism for producing the large holes observed in the discs ofCoKu Tau-4, GM Aur and DM Tau.
