SGR和AXP被认为是七巨头的祖先

SGRs and AXPs proposed as ancestors of the Magnificent seven

Brian Niebergal, Rachid Ouyed, Denis Leahy

摘要:

最近提出的孤立中子星表面温度和磁场之间的相关性似乎对SGR、AXP和X射线暗淡的孤立中子星(XDIN;特别是壮丽七或M7)不起作用。相反,通过诉诸色香味锁夸克星(CFLQS),我们找到了一个更自然的解释。在这张照片中,加热是由无壳超导夸克星的磁通量驱逐提供的。结合我们以前关于SGRs,AXP和XDIN作为CFLQS的可能性的研究,这提供了另一个证据,证明这些对象都是相关的。具体来说,我们建议XDIN是SGR和AXP的后代。

英文摘要:

The recently suggested correlation between the surface temperature and the magnetic field in isolated neutron stars does not seem to work well for SGRs, AXPs and X-ray dim isolated neutron stars (XDINs; specifically the Magnificent Seven or M7). Instead by appealing to a Color-Flavor Locked Quark Star (CFLQS) we find a more natural explanation. In this picture, the heating is provided by magnetic flux expulsion from a crust-less superconducting quark star. Combined with our previous studies concerning the possibility of SGRs, AXPs, and XDINs as CFLQSs, this provides another piece of evidence that these objects are all related. Specifically, we propose that XDINs are the descendants of SGRs and AXPs.
