关于倾斜盘和负超峰的起源

On the origin of tilted disks and negative superhumps

J. Smak

摘要:

激变变星中倾斜盘的起源可以用一个包含流盘相互作用的模型来解释。倾斜,旋进盘的原因周期性可变的不对称性的照射的两个半球的二次分量,导致在可变的垂直分量的流的速度。下面的流盘相互作用提供额外的垂直加速度的磁盘元素需要产生和维持磁盘倾斜。基于该模型的预测与观测结果相比毫不逊色。

英文摘要:

The origin of tilted disks in cataclysmic variables is explained in terms of a model involving the stream-disk interactions. Tilted, precessing disk causes periodically variable asymmetry in the irradiation of the two hemispheres of the secondary component, resulting in variable vertical component of the velocity of the stream. The following stream-disk interactions provide additional vertical acceleration to disk elements needed to produce and maintain disk tilt. Predictions based on this model compare favorably with observations.
