Constraining quark-hadron interface tension in the multi-messenger era

Understand

We study the interface effects of quark-hadron mixed phase in compact stars.

• The properties of nuclear matter are obtained based on the relativistic-mean-field model.
• For the quark phase, we adopt perturbation model with running quark masses and coupling constant.
• At certain choices of parameter sets, it is found that varying the quark-hadron interface tension will have sizable effects on the radii ($\Delta R \approx 600$ m) and tidal deformabilities ($\Delta \Lambda/\Lambda \approx 50\%$) of hybrid stars.
