  "abstract": "If only one family of \"neutron stars\" exists, their maximum mass must be equal or larger than $2 M_\\odot$ and then only in less than about $18\\%$ of cases the outcome of the merger of two neutron stars is a direct collapse to a black hole, since the newly formed system can avoid the collapse at least until differential rotation is present. In the so-called two-families scenario, stars made of hadrons are stable only up to about $1.5-1.6 M_\\odot$, while the most massive compact stars are entirely made of strange quark matter. We show that in this scenario the outcome of the merger of two neutron stars is a prompt collapse in at least $34\\%$ of the cases. It will therefore be easy to discriminate between the two scenarios once the gravitational waves emitted at the moment of the merger are detected.",
