论文摘要
无线电发射的中子星人群包括旋转周期的物体，范围从毫秒到数十秒。随着它们的年龄和旋转的速度较慢，预计无线电发射将停止。我们介绍了超长时期发射的中子星J0901-4046的发现，其自旋特性与已知的自旋和磁性驱动的中子星星不同。以75.88 s的旋转状态，5.3的特征年龄和一个狭窄的脉搏效果周期，尚不确定无线电发射是如何产生的，并挑战了我们当前对这些系统如何发展的理解。无线电发射具有独特的光谱时期特性，例如准周期性和部分空白，可为发射机制提供重要的线索。检测类似的来源在观察方面具有挑战性，这意味着较大的未被发现的人群。我们的发现确定了超长时期的中子星的存在，这表明可能与高度磁性中子星的演变，超长时期磁铁和快速无线电爆发有联系
The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emission is expected to cease. We present the discovery of an ultra-long period radio-emitting neutron star, J0901-4046, with spin properties distinct from the known spin and magnetic-decay powered neutron stars. With a spin-period of 75.88 s, a characteristic age of 5.3 Myr, and a narrow pulse duty-cycle, it is uncertain how radio emission is generated and challenges our current understanding of how these systems evolve. The radio emission has unique spectro-temporal properties such as quasi-periodicity and partial nulling that provide important clues to the emission mechanism. Detecting similar sources is observationally challenging, which implies a larger undetected population. Our discovery establishes the existence of ultra-long period neutron stars, suggesting a possible connection to the evolution of highly magnetized neutron stars, ultra-long period magnetars, and fast radio bursts
