Abstract Neutron star (NS) mergers provide us with information rich in physics using multimessenger astrophysical observations. One of the probable remnants of such a merger is a differentially rotating hot hypermassive NS. The stability of the merger remnant crucially depends on the underlying equation of state and thus provides a method to probe the nature of dense matter in NSs. In this work, we search for possible signatures of strangeness-containing matter in NS interiors on the secular stability of the merger remnant. We also use recently proposed methods to make a rough estimate of the collapse time of the merger remnant and the threshold mass above which the merger promptly collapses to a black hole.
