- We show that if $α$ is a regular cardinal, $\mathcal{D}$ is an $α$-compactly generated triangulated category, in the sense of Neeman \cite{N}, and $τ$ is a t-structure in $\mathcal{D}$ generated by a set of $α$-compact objects, then the heart of $τ$ is a locally $α$-presentable (not necessarily Ab5) abelian category. As a consequence, in a well-generated triangulated category any t-structure generated by a set of objects has a heart with a set of generators.
