LMC X-3可能是类似宇宙学伽玛暴的GRB的遗迹

LMC X-3 May Be a Relic of a GRB Similar to Cosmological GRBs

G. E. Brown, C. -H. Lee, E. Moreno Mendez

摘要:

目前高亮度长伽马射线暴的情况受到Fruchter等人(2006)论文的强烈影响。然而,本文的主要论点,这些伽玛暴发生在低金属含量的不规则星系是基于相当多的观测结果的收集,虽然主要的论文无疑是正确的,该文件没有解释的动力学,产生这样的伽玛暴和大部分的讨论没有直接涉及的主要论文是错误的。我们提出了一个动力学,并阐明如何Fruchter等人(2006)的结果可能会被测试,在我们附近的LMC,这表明LMC X-3是一个高光度爆炸的遗迹,可能伴随着伽玛暴和超新星爆炸。检验我们建议的方法是测量当前黑洞的系统速度。修正了Fruchter等人在恒星演化中的错误,使GRB的研究与之一致,证明了亚亮GRB 060218的中心引擎是一个低质量的黑洞。

英文摘要:

The present scenario for high-luminosity long gamma-ray bursts is strongly influenced by the paper of Fruchter et al. (2006). Whereas the main contention of this paper that these GRBs occur in low-metallicity irregular galaxies is based on a considerable collection of observational results and although the main thesis is doubtless correct, the paper does not explain the dynamics that produces such GRBs and much of the discussion not directly concerning the main thesis is wrong. We propose a dynamics and elucidate how the Fruchter et al. (2006) results may be tested, in our neighborhood in the LMC, suggesting that LMC X-3 is a relic of a high luminosity explosion, probably accompanied by a GRB and hypernova explosion. The way to test our suggestion is to measure the system velocity of the present black hole. We correct errors of the Fruchter et al. paper in stellar evolution, so that the study of GRBs is consistent with it. We show that the subluminous GRB 060218 had a low-mass black hole as central engine.
