论文摘要

与天文数据的收集相同,信号通常由噪声主导。但是,在执行光曲线的FTS时,重新填充数据可以在较低的频率下改善信噪比(SNR)。 Using data collected from the Kepler space telescope, we sequentially re-binned data three times to investigate the SNR improvement of lower frequency (< 17 microHz) variability in white dwarf KIC 8626021. We found that the SNR at approximately 5.8 microHz greatly improved through this process, and we postulate that this frequency is linked to the rotation of KIC 8626021.

As is common with the collection of astronomical data, signals are frequently dominated by noise. However, when performing FTs of light curves, re-binning data can improve the signal-to-noise ratio (SNR) at lower frequencies. Using data collected from the Kepler space telescope, we sequentially re-binned data three times to investigate the SNR improvement of lower frequency (< 17 microHz) variability in white dwarf KIC 8626021. We found that the SNR at approximately 5.8 microHz greatly improved through this process, and we postulate that this frequency is linked to the rotation of KIC 8626021.
