大多数大质量中子星的大小可能会揭示其奇异的核心

The size of most massive neutron stars may reveal its exotic cores

Neha Gupta, P. Arumugam

摘要:

最近对质量最大的脉冲星J 1614 -2230($(1.97\pm0.04)$太阳质量($M_\odot$))的高精度观测表明,许多考虑核内奇异粒子的核模型可以被排除。然而,最近的许多计算可以用各种奇异粒子来解释这颗恒星,使得精确的质量测量不足以得出奇异核心的结论。我们研究这样的恒星的半径的敏感性,其核心的细节。通过我们的计算和分析,我们表明,对于质量最大的中子星,通过精确观测其半径,可以确定奇异核的存在。

英文摘要:

The recent high precision observation of the most massive pulsar J1614-2230 with $(1.97\pm0.04)$ solar mass ($M_\odot$) was reported with a suggestion that many nuclear models which consider exotic particles in the core could be ruled out. However, many recent calculations could explain this star with various exotic particles, rendering the precise mass measurements insufficient to conclude on exotic cores. We examine the sensitivity of the radius of such a star to the details of its core. With our calculations and analysis, here we show that, for the most massive neutron star, with a precise observation of its radius it is possible to ascertain the presence of exotic cores.
