Stellar mass twin configurations are obtained if a strong first-order phase transition occurs in the interior of a compact star. In the mass–radius diagram of compact stars, this leads to a third branch of gravitationally stable stars with features that are very different from those of white dwarfs and neutron stars. We discuss rotating hybrid star sequences in the slow rotation approximation and in full General Relativity and draw conclusions for an upper limit on the maximum mass of non-rotating compact stars, which has recently been deduced from the observation of the merger event GW170817.
