Abstract
We consider a quintessence model for dark energy interacting with dark matter via a Yukawa interaction. To put constraints on this model we use the CMB measurements from the Planck satellite together with BAO, SNIa and data. We conclude that this is a viable model and an appropriate scalar potential can favor the interacting scenario.

Comments
10 pages, 6 figures, 3 tables. We fixed a bug in our numerical implementation and redid all the analysis. As a result: the previous divergent behavior at low multipoles is now absent; there is now more room for larger values of the interaction; the interaction become more favorable using low redshift measurements; the interaction become more plausible to help alleviating the coincidence problem
