| 英文摘要 | The state equation for strangeon matter is very stiff due to the non-relativistic nature of its particles and their repulsive interaction, such that pulsar masses as high as 3M (aS (TM)) would be expected. However, an adiabatic sound speed, c (s) = aea,P/a,rho, is usually superluminal in strangeon matter, and the dynamic response of a strangeon star (e.g., binary merger) is not tractable in numerical simulations. In this study, we examined signal propagation in strangeon matter and calculate the actual propagation speed, c (signal). We found that the causality condition, c (signal) < c, is satisfied and the signal speed is presented as a function of stellar radius. |
