摘要

磁星是具有超强磁场的中子星,其磁场强度可超过 1e15 G。一些磁星(即所谓的软伽马中继星)偶尔会表现出非常强大的能量释放过程,从而产生异常强烈的电磁辐射耀斑。尽管有许多假设,但这些耀斑的机制仍然是个谜。在耀斑的后辉光中,人们经常观测到磁星发射的准周期振荡(QPOs)。它们被解释为耀斑激发的恒星振动,有助于探索磁星活动的本质。讨论了用于解释磁星 QPO 的理论的不完整性。

Powerful flares and magneto-elastic oscillations of magnetars
Magnetars are neutron stars with superstrong magnetic fields which can exceed 1e15 G. Some magnetars (the so-called soft gamma-repeaters) demonstrate occasionally very powerful processes of energy release, which result in exceptionally strong flares of electromagnetic radiation. It is believed that these flares are associated with the presence of superstrong magnetic fields. Despite many hypotheses, the mechanism of these flares remains a mystery. In afterglows of the flares, one has often observed quasi-periodic oscillations (QPOs) of magnetar emission. They are interpreted as stellar vibrations, excited by the flares, which are useful for exploring the nature of magnetar activity. The incompleteness of theories employed to interpret magnetar QPOs is discussed.
