description The top-quark is the heaviest fundamental particle known, with a mass close to the electroweak symmetry breaking scale that constrains, together with the W mass, the Higgs boson mass. The measurements of the top-quark mass in the lepton + jets and all-hadronic channels are summarised in this proceedings. The precise measurement of the top-quark properties at the LHC is of great interest since it offers both stringent tests of the Standard Model (SM) and possible pathways to dicovering new physics. The ATLAS experiment has measured many of the top-quark properties with unprecedented precision in 2011. This article presents most recent measurements of top-quark properties from the ATLAS detector. In particular, W boson polarization in top-quark decays, the charge asymmetry and the ttbar spin correlation.
