We present the first observational confirmation for an extended circumstellar dust disk around $ ϵ $ ~Eri .
The observations were obtained with the bolometer array SIMBA at the 15 m radio telescope SEST in Chile and measure the dust continuum at 1.2 mm .
The emission , with a total flux of 21.4 mJy and a rms of 2.2 mJy/beam , is resolved to a deconvolved size of 27 \aas@@fstack { \prime \prime } 4 which corresponds to 88 AU .
No clear indication for a ring-like disk structure is seen , possibly also due to the telescope ’ s large beam width of 24 ^ { \prime \prime } .
Models of the object ’ s spectral energy distribution from IR to mm-wavelengths show that the emission can also be explained by a simple disk model .
We further demonstrate the strong influence of noise and propose to be cautious with interpretations of the ring substructure .
