论文摘要
我们在爆发的上升阶段介绍了银河黑孔二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制二进制文件，该爆发的上升阶段持续了约65天，从2010年9月25日开始。反射光谱和连续拟合方法，以估计黑洞的自旋。我们探索了当前不确定性在黑洞质量，倾斜度和距离以及积聚率上允许的整个参数范围。我们表明，对于约95％的参数空间和质量吸积率非常合理的上限，黑洞的旋转必须为负。这是银河黑孔二进制中负自旋的首次清晰检测。
We present the results of spectral analysis of the galactic black-hole binary MAXI J1659--152 in the rising phase of the outburst that lasted for about 65 days starting on 2010 September 25. The presence of a broad Fe line, verified by Monte-Carlo simulations, and coverage of a wide energy band by utilizing the combined spectral capabilities of XMM-Newton/EPIC-pn and RXTE/PCA allowed us to use a combination of reflection spectroscopy and continuum fitting methods to estimate the spin of the black hole. We explored the entire parameter range allowed by the present uncertainties on black-hole mass, inclination, and distance as well as the accretion rate. We show that for about 95 percentage of parameter space and very reasonable upper limits on mass accretion rate, the spin of the black hole has to be negative. This is the first clear detection of negative spin in a galactic black-hole binary.
