Top Quark Mass and Top Properties at ATLAS

The measurement of the top quark mass and other top quark properties, such as the $W$ boson polarization, flavor changing neutral currents (FCNC), anomalous production with large missing transverse energy ($met$) and charge asymmetry in top quark pair ( tbar) production, at ATLAS~cite{} are presented in this paper. %The measurements were performed mostly in the tbar lepton+jets channel, but also in the dilepton and single top channels. The results were obtained using the data taken during the 2010 proton-proton run at a center-of-mass energy of $7TeV$ which corresponds to an integrated luminosity of $35ipb$ with a luminosity uncertainty of $3.4%$~cite{}. The charge asymmetry was measured with data taken during 2011 which corresponds to an integrated luminosity of $700ipb$ with a luminosity uncertainty of $4.5%$~cite{}.
