Sumario:The large top quark samples in top quark pair and single top production have yielded measurements of the production cross-section of unprecedented precision and in new kinematic regimes. They have also enabled new measurements of top quark properties that were previously inaccessible. In this contribution, the highlights of the ATLAS top quark precision program are presented. ATLAS presents in particular new measurements of the single top-quark production cross section in the s-channel as well as of the charge asymmetry in top-quark pair production, the charge asymmetry in top-quark pair production in association with a photon, and energy asymmetry in top-quark pair production in association with an additional jet with high transverse momentum.
