Top quark studies with the ATLAS detector

The latest studies of top quark production measurement in proton-proton collisions at a centre-of-mass energy of 7 and 8 TeV with the ATLAS detector are reported. The talk will present recent results on the top pair production inclusive cross sections, top pair production differential cross section in resolved and boosted regime, single top-quark productions cross sections measured for t-channel, s-channel and W-boson associated processes. as well as d the CKM matrix element |Vtb| determination. All the results are compared with theoretical expectations. Latest ATLAS results on top mass measurements will be also shown in terms of direct and mass pole results.
