摘要

在过去的几年里,由于直接或间接的证据,人们对大质量中子星和白矮星产生了极大的兴趣。最近探测到的引力波事件GW190814证实了在所谓的质量间隙内存在质量高达~ 2.5-2.67 M⊙的致密恒星,这表明存在高质量中子星。利用大质量致密天体的主要目标之一是解释最近探测到的十几颗Ia型超新星,它们的特点在于它们不寻常的光曲线,特别是高亮度和低喷射速度。在最近的一系列论文中,我们的研究小组提出,具有超级钱德拉塞卡质量的高磁化白矮星可能是这些特殊超新星的祖先的有希望的候选者。这些磁化恒星的质量半径关系与非磁化恒星的质量半径关系明显不同,这导致了修正的超级钱德拉塞卡质量极限。这些致密恒星具有更广泛的意义,包括软伽马射线中继器、异常x射线脉冲星、白矮星脉冲星和引力辐射。在这里,我们回顾了该学科在过去十年左右的发展,描述了该学科目前的总体艺术状态。我们主要讨论了这些有趣的恒星可能的形成渠道以及直接探测方法的有效性。这些被磁化的恒星可以产生许多有趣的结果,包括重新考虑它们作为可能的标准蜡烛。

Formation, Possible Detection and Consequences of Highly Magnetized Compact Stars
Over the past several years, there has been enormous interest in massive neutron stars and white dwarfs due to either their direct or indirect evidence. The recent detection of gravitational wave event GW190814 has confirmed the existence of compact stars with masses as high as ∼2.5–2.67 M⊙ within the so-called mass gap, indicating the existence of highly massive neutron stars. One of the primary goals to invoke massive compact objects was to explain the recent detections of over a dozen Type Ia supernovae, whose peculiarity lies with their unusual light curve, in particular the high luminosity and low ejecta velocity. In a series of recent papers, our group has proposed that highly magnetised white dwarfs with super-Chandrasekhar masses can be promising candidates for the progenitors of these peculiar supernovae. The mass-radius relations of these magnetised stars are significantly different from those of their non-magnetised counterparts, which leads to a revised super-Chandrasekhar mass-limit. These compact stars have wider ranging implications, including those for soft gamma-ray repeaters, anomalous X-ray pulsars, white dwarf pulsars and gravitational radiation. Here we review the development of the subject over the last decade or so, describing the overall state of the art of the subject as it stands now. We mainly touch upon the possible formation channels of these intriguing stars as well as the effectiveness of direct detection methods. These magnetised stars can have many interesting consequences, including reconsideration of them as possible standard candles.
