Confirming Mode Identifications in DAV G 29-38

Variable luminosity White Dwarf Giclas 29-38, of spectral type DAV, has been previously observed to have large amplitude pulsation modes of varying frequency and amplitude. Using time series light curve data spanning 23 days from the TESS (Transiting Exoplanet Survey Satellite) spacecraft, we have employed advanced Fourier Transform techniques to extrapolate the individual pulsation modes of the star. These pulsation modes have been compared to past results gathered by Kleinman et al. (1996). A White Dwarf pulsation modeling code, based on the previous work of Montgomery (2005) and Montgomery et al. (2010), was used to independently confirm the ℓ and m values for two pulsation modes determined by Uzundag et al. with varying success. Future study will use observations from the Hubble Space Telescope (HST) to create a model of G 29-38’s surface during pulsation events, allowing for the surface composition of different areas of the stellar surface to be estimated.
