【摘要】 采用一种新的乌龟坐标变换,我们在Damour-Ruffini-Sannan理论的框架下研究了做变加速直线运动和任意加速运动的Kinnersley黑洞中Weyl中微子的Hawking辐射现象结果发现,与采用通常乌龟坐标变换所得到的结果比较,Hawking辐射的谱分布仍然呈黑体谱形式但辐射温度明显不同;此外,对任意加速运动的Kinnersley黑洞而言,其Hawking辐射温度除受加速度大小的变化影响外,还与加速度在角度方向上的变化率有关.更多还原

【Abstract】 Under different tortoise coordinate transformations,we investigate the Hawking radiations of Weyl neutrinos in rectilinearly-accelerating and arbitrarily-accelerating Kinnersley black holes.Our discussion is based on the DamourRuffini-Sannan theory and find that,all the derived Hawking radiation spectra show-still the blackbody ones,but the Haw-king temperatures are significantly different.Additionally,it is shown that,for arbitrarily-accelerating Kinnersley black holes,the Hawking radiation temperatures depend on the varying of acceleration in both the numerical sizes and angles.更多还原
