Abstract

KIC 8462852 is a star of interest due to it’s unusual flux phenomena. Although there is now a better understanding of the star’s photometric fluctuations, the star has yet to be fully characterized. Our research focuses on determining the chemical composition of KIC 8462852. Here we present our analysis of medium-resolution spectra obtained with the 3.5 meter WIYN telescope and HYDRA spectrograph in single-object mode to determine the star’s chemical abundance. We have used the MOOG spectral analysis software and KURUCZ model atmospheres to determine abundances via spectral synthesis. Of the elements analyzed, the abundances of iron, nickel, and silicon are comparable to that of the sun. The only outlier is calcium which was found to be more enhanced in this star than that of the sun.
