Abstract
We present a comparison of the pulsation frequencies of the rapidly oscillating Ap star (roAp) HD 122970 with previous measurements of this star’s pulsations. RoAp stars are a subclass of Main Sequence stars that pulsate with periods between 5-23 minutes. HD 122970 has been shown to be a roAp star based on light curves developed from previous observations. These observations show that HD 122970 has a pulsation period of 11.093 minutes (frequency of 1.5025 mHz). This study investigates whether HD 122970 is still pulsating in this manner by developing a differential light curve of this star. We then use digital fast Fourier Analysis, and Least Squares Fitting to extract the potential pulsation frequencies of HD 122970.
