δSct星星KIC 7106205在一个单一的p模式中表现出振幅调制，而所有其他的p和g模式在开普勒数据集的1470 d内保持稳定的振幅和相位。将数据分成30个等长的时间仓，并计算一系列连续的傅立叶变换。一个固定的频率，从所有数据的最小二乘拟合计算，允许振幅和相位为每个模式在每个时间箱被跟踪。缺失的p模式能量没有转移到任何其他可见模式。
TheδSct star KIC 7106205 showed amplitude modulation in a single p mode, whilst all other p and g modes remained stable in amplitude and phase over 1470 d of theKeplerdataset. The data were divided into 30 time bins of equal length and a series of consecutive Fourier transforms was calculated. A fixed frequency, calculated from a least-squares fit of all data, allowed amplitude and phase for every mode in each time bin to be tracked. The missing p mode energy was not transferred to any other visible modes.
