Variation of delta baryon mass and hybrid star properties in static and rotating conditions

Understand

The possible conditions for hadron-quark phase transition in hybrid star cores are investigated in the present work.

• For the hadronic matter part the effective chiral model is adopted.
• Exotic baryonic degrees like hyperons and the delta baryons are also taken into account.
• As $\Delta$s posses Breit-Wigner mass distribution ($1232 \pm 120$ MeV), the hadronic equation of state is obtained by varying the mass of the delta baryons in this range.
