在矮新星爆发期间观测到的一类振荡被解释为这些系统中吸积盘的振荡。这些振荡是准周期的，相干时间通常在3到15个周期之间。结果表明，高磁雷诺数下的磁场重联可以驱动圆盘振荡。预期的磁盘磁场的随机几何可以自然地产生所观察到的相非相干。21日引用。
A class of oscillations observed during eruption of dwarf novae has been interpreted as oscillations of the accretion disks in these systems.These oscillations are quasi-periodic with coherence times typically between three and 15 cycles. It is shown that magnetic field reconnection at high magnetic Reynolds number can drive disk oscillations. The expected stochastic geometry of disk magnetic fields could naturally produce the observed phase incoherency. 21 references.
