Measurements of the Properties of the Top Quark

We review recent measurements of the properties of the top quark: the decay width of the top quark, of spin correlations between the top and the antitop quarks in $\text{ttbar}$ production, the $W$ boson helicity in top decays, the strong colour flow in $\text{ttbar}$ events, and the asymmetry of $\text{ttbar}$ production due to the strong colour charge. The measurements are performed on data samples of up to 5.4 \fb\ of integrated luminosity acquired by the CDF and D0 collaborations in Run II of the Fermilab Tevatron $p\bar{p}$ collider at a centre-of-mass energy of $\sqrt{s}=1.96\text{TeV}$.
