磁星的形成:孤立之谜

Formation Scenario of Magnetars: The Puzzle of Isolation

Nirvikar Prasad

摘要:

磁星(SGR和AXP)是中子星演化的重要途径之一。这些天体在其表面有一个超强磁场$B \sim 10^{15}$ G,并显示出持续的X射线脉动和瞬时爆发。到目前为止,已知有14颗磁星:5颗SGR(4颗确认,1颗候选)和9颗AXP(7颗确认,2颗候选)。这是一个开放的难题,所有这些对象是孤立的,没有发现在二进制。我们将讨论可能导致这种情况的形成方案。

英文摘要:

Magnetars (SGRs and AXPs) are one of the most evolutionary paths of a neutron star. These objects have an ultra-strong magnetic field $B \sim 10^{15}$ G at their surface and show persistent X-ray pulsations and transient bursts. Till date there are 14 magnetars known: 5 SGRs (4 confirmed, 1 candidate) and 9 AXPs (7 confirmed, 2 candidates). It is an open puzzle that all these objects are isolated and none have been found in binaries. We discuss the formation scenario which can lead to such a situation.
