In this letter, we discuss the possibility of the mass-gap object in the GW190814 event being different classes of compact objects: hadronic neutron stars with nucleons only, hadronic stars with nucleons and hyperons, hybrid stars with nucleons and quarks, hybrid stars with nucleons, hyperons and quarks, and strange stars satisfying the Bodmer-Witten conjecture. We show that for the current limit of the observational constraints none of these possibilities can be ruled out.
