Abstract

A question about the origin of a pulsar-like white dwarf in the low-mass binary system AR Scorpii is discussed. In our consideration we follow the accretion-driven spin-up scenario previously developed to explain the origin of a strongly magnetized fast rotating white dwarf in AE Aquarii. We find that the origin of AR Scorpii can be explained within this scenario provided the surface magnetic field of the white dwarf during the spin-up epoch was screened by the accreting matter by a factor of 50-100. This finding suggests that the fast rotating strongly magnetized white dwarfs in both systems were formed by a common mechanism.

天蝎座AE和水瓶座AE进化轨迹的一个自旋上升阶段
讨论了低质量双星系统天蝎座AR中一颗脉冲星样白矮星的起源问题。在我们的考虑中,我们遵循先前开发的吸积驱动的自旋情景来解释AE水瓶座中一颗强磁化快速旋转白矮星的起源。我们发现天蝎座AR的起源可以在这种情况下解释,只要白矮星在自旋上升时期的表面磁场被吸积物质屏蔽了50-100倍。这一发现表明,两个系统中快速旋转的强磁化白矮星是由一个共同的机制形成的。
