标题： Oscillations of hypothetical strange stars as an efficient source ultra-high-energy particles

摘要： 我们研究了奇异夸克物质（SQM）天体，如恒星和行星，在恒星系统中受到潮汐相互作用引起的径向振荡时的动力学行为。 我们的研究显示，由于其表面临界质量密度为4.7*10^{14} g/cm^3，SQM天体可以有效地将机械能转化为强子能量，低于此密度时SQM会变得不稳定并衰变为光子、强子和轻子。 我们表明，即使振幅很小的径向振荡，半径变化仅为0.1%，也可能在SQM恒星表面产生显著的激发能量。 这种激发能量在大约1毫秒的短时间尺度内迅速转化为电磁能量，可能导致可观测的天体物理现象。 高振幅振荡可能导致SQM恒星的碎片化或解体，这对于包含SQM天体的双星系统的演化以及引力波的发射具有重要意义。 显示英文摘要

摘要： We investigate the dynamical behavior of strange quark matter (SQM) objects, such as stars and planets, when subjected to radial oscillations induced by tidal interactions in stellar systems. Our study demonstrates that SQM objects can efficiently convert mechanical energy into hadronic energy due to the critical mass density at their surfaces of 4.7*10^{14} g/cm^3, below which SQM becomes unstable and decays into photons, hadrons, and leptons. We show that even small-amplitude radial oscillations, with a radius change of as little as 0.1%, can result in significant excitation energies near the surface of SQM stars. This excitation energy is rapidly converted into electromagnetic energy over short timescales approximately 1 ms, potentially leading to observable astrophysical phenomena. Higher amplitude oscillations may cause fragmentation or dissolution of SQM stars, which has important implications for the evolution of binary systems containing SQM objects and the emission of gravitational waves.
