Exploring new techniques for analyzing variability in white dwarf KIC 8626021
Authors: Thomas Huckans, Peter Stine
Abstract: 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.
