能量最小化的两个黑洞初始数据

Energy-minimizing two black holes initial data

Jacek Jezierski, Jerzy Kijowski, Szymon Leski

摘要:

本文提出了构造两个黑洞引力场“基态”真空初始数据的一种尝试。基态被定义为在黑洞质量和距离固定的数据类内使ADM质量最小化的引力初始数据。为了参数化两个孔的不同几何布置(以及它们的距离),我们使用适当选择的比例因子。提出了一种分析ADM质量和视界质量(面积)随引力自由度变化的方法。Misner的初始数据进行了分析,在这种情况下:它表明,他们不减少ADM质量。

英文摘要:

An attempt to construct the ``ground state'' vacuum initial data for the gravitational field surrounding two black holes is presented. The ground state is defined as the gravitational initial data minimizing the ADM mass within the class of data for which the masses of the holes and their distance are fixed. To parameterize different geometric arrangements of the two holes (and, therefore, their distance) we use an appropriately chosen scale factor. A method for analyzing the variations of the ADM mass and the masses (areas) of the horizons in terms of gravitational degrees of freedom is proposed. The Misner initial data are analyzed in this context: it is shown that they do not minimize the ADM mass.
