Abstract
Images of ZZ Ceti variable white dwarf GD 99 will be taken between dates March 2, 2022, and April 30, 2022, using the CCD camera in the filter r. GD 99 is known to have unusual pulsation periods of 1058.1, 228.7, 1026.1 and 223.9s with an amplitude of 7.0, 5.8, 4.0, and 2.4 mmag, respectively. We want to replicate and confirm the known periods and amplitudes. We will use AstroImageJ to perform the photometry data reduction to obtain a light curve and Period04 to find the pulsation and amplitude of GD 99. Variable white dwarfs' brightness variations are due to temperature variations on the star’s surfaces, ultimately, we want to create an O-C diagram to monitor the cooling of GD 99.
