Being the heaviest fermion various extensions of the Standard Model predict new Physics to couple first to the top quark. The talk presents results from searches for new resonances decaying to a top-antitop pair, including the use of boosted top quark reconstruction techniques. In addition we will review searches for b* resonances decaying to a W boson and a single top quark as well as W', a heavy gauge boson, which decays to a top and a b quarks These searches use the data sample recorded by the ATLAS experiment at the LHC.
