Hybrid stars tend to have lower frequencies than plain nuclear matter stars or hyperon matter. It can be seen that the scaling with the mass is quite independent of the equation of state, specially for the fundamental modes. The empirical parameters are more sensitive to the hyperon core, specially at high densities. Here it can be seen that the scaling with the central pressure is also quite independent of the equation of state. These curves branch once the EOS is affected by the phase transition. Damping time of the fundamental wI mode vs central pressure in logarithmic scale, for the EOS considered in Section V. This site is also available in the following languages:

Wimode can be seen that the scaling wimode the mass is quite independent of the equation of state, specially for the fundamental modes. Note that at high pressures different phase transitions are taken into account, affecting the stiffness of the EOS.

Wimode phase transitions that can be seen in the previous figure affects the frequency curves. We plot configurations up to the maximum stable mass. This universal relation could be used to estimate for example, the central pressure of the star independently of the EOS.

In a similar way to the frequency, the phase transitions in the equations of state are clearly reflected in the branching of the wimode time curves. The damping time does not vanish in the limit compactness as wimode frequency does.

Here it wimode be seen that the scaling with the central pressure is also quite wimode of the equation of state.

For low compactness, there are no or almost no wimode in the core of the star, so at this point all the configurations wimode basically plain nuclear matter stars. Privacy policy Powered by Invenio v1.

Typically, wimode with hyperon matter have bigger radius than nuclear matter stars of the same wimode. The arrow indicates increasing compactness.
