The heaviest known elementary particle, the top quark, provides an interesting area of research. Its high mass and short lifetime make it to be of special interest in the hunt for physics beyond the standard model. In my talk I will present a potpourri of recent analyses in the top sector, using LHC proton-proton collision data at 13TeV centre-of-mass energy, recorded with the ATLAS detector. The presented analyses are a new result on top quark spin correlations, a study of QCD colour-flow in top events, and the connection of the top to the Higgs boson.
