双星系统中磁星的起源

Origin of magnetars in binary systems

S. B. Popov

摘要:

我回顾了磁星形成的几个方案,通过自旋的祖先,由于与它的同伴的相互作用在二进制系统。大多数情况下,这些演化通道导致孤立磁星的形成,事实上,这类磁星的所有公认来源都是单一物体。然而,一些双星可以存活下来,并且已经提出了几个吸积磁星的候选者。我讨论了这个问题,并得出结论,新的吸积模型可以解释拟议的候选人没有大的磁场对应的磁场演化模型的属性。

英文摘要:

I review several scenarios of magnetar formation in binary systems via spin-up of a progenitor due to interaction with its companion. Mostly, these evolutionary channels lead to formation of isolated magnetars, and indeed, all well-established sources of this class are single objects. However, some binaries can survive, and several candidates to accreting magnetars have been proposed. I discuss this issue, and conclude that new accretion models can explain properties of the proposed candidates without large magnetic field in correspondence with models of magnetic field evolution.
