AI总结:

研究极化物质中中微子磁矩辐射的自旋光效应,发现极化可增强或抑制辐射,并引入不对称性,为探测中子星内部结构提供可能。

摘要:

中微子的自旋光($SL\ u$)是中微子在外界条件(场或物质)中运动时,其磁矩发出的电磁辐射。该效应在致密天体(如中子星)的极端稠密物质中可能具有重要意义。如果被探测到,这种辐射将提供一个很好的机会来研究中微子的性质以及它们所穿过的介质,因为辐射的性质取决于两者。受核物质自旋极化可能性的启发,本文研究了在净物质极化影响下$SL\ u$获得的新性质。我们证明极化可以增强或完全抑制辐射。此外,它给致密天体的总辐射引入了一种特征不对称性,这可能是依赖于物质极化和恒星内部磁场(如果磁场与恒星物质极化相关)的可观测特征。该研究可能对中子星和磁星的物理学产生影响,使我们更接近研究其内部结构的可能性。

英文摘要:

The Spin Light of neutrino ($SLν$) is an electromagnetic radiation of the neutrino magnetic moment emitted when neutrino moves in external conditions (fields or matter). The effect can be of significance in the extremely dense matter of compact astrophysical objects such as neutron stars (NS). If detected, this radiation could provide a fair opportunity to study the properties of neutrinos and the medium through which they move, since the properties of the radiation depend on both. Motivated by the possibility of the nuclear matter spin-polarization, in this paper, we study the new properties to $SLν$ obtained under the influence of net matter polarization. We demonstrate that the polarization can enhance or completely suppress the radiation. Also, it introduces a characteristic asymmetry into the total radiation from the compact object, which could be an observable feature dependent on the matter polarization and the magnetic field inside the stellar (if the field is connected to the stellar matter polarization). The research may have implications for the physics of NS and magnetars, bringing us closer to the possibility of studying their internal structure.
