论文摘要
在Hyperos存在的情况下，在中子星（NS）核心的冷致密物质中检查了$δ$共振的可能存在。 $δ$质量在其形成中的变化的不同影响以及在这项工作中使用有效的手性模型研究了状态方程（EOS），并借助参数化的tolman-oppenheimer-volkoff方程（PTOV）来计算结果的NS属性，以在质量质量NS的情况下提出压力的两个重要功能。在大规模脉冲脉冲（如PSR J1614-2230和PSR J0348-0432）中，考虑了修改/参数化的惯性压力和自我实现的概念，重新探索并解决了$δ$拼图。可以看出，尽管像超子这样的外来物质的存在和$δ$ s可以大大柔和EOS，但可以通过参数化的静水平衡条件理论成功地解释它们在大量NSS中的存在。这项工作的结果还满足了$ r_ {1.4} $和$ r_ {1.6} $的约束，从重力波（GW170817）检测二进制NS合并的检测。 PSR J0737-3039对Baryonic质量的限制也对所有考虑的$δ$块的PTOV方程解决方案感到满意。
The possible existence of $Δ$ resonances is inspected in the cold dense matter of neutron star (NS) core in presence of the hyperons. The diverse effects of variation in $Δ$ mass on their formation and the equation of state (EoS) are studied in this work with an effective chiral model and the resultant NS properties are calculated with the help of parameterized Tolman-Oppenheimer-Volkoff equations (PTOV) to bring out the two important features of pressure in the context of massive NSs. The $Δ$ puzzle is re-explored and resolved taking into account the concept of modified/parameterized inertial pressure and self-gravity in case of massive pulsars like PSR J1614-2230 and PSR J0348-0432. It is seen that although the presence of exotic matter like the hyperons and the $Δ$s softens the EoS considerably, their presence in massive NSs can be successfully explained with the theory of parameterized hydrostatic equilibrium conditions. The results of this work also satisfy the constraints on $R_{1.4}$ and $R_{1.6}$ from the gravitational wave (GW170817) detection of binary NS merger. The constraint on baryonic mass from PSR J0737-3039 is also satisfied with the solutions of the PTOV equations for all the $Δ$ masses considered.
