symmetric monoidal (∞,1)-category of spectra
A Hopf algebra is called involutive (or involutory, e.g. Kuperberg 91, Virelizier 02, Sec. 1.7) if its antipode is an involution.
Since the antipode of a Hopf algebra is necessarily an anti-homomorphism of the underlying associative algebra-structure (by this Prop.), an involutive Hopf algebra is in particular a star algebra.
