| Abstract: |
The nonlinear sum and difference frequencies found in the frequency
spectra of pulsating white dwarf stars clearly contain information
about the structure of the stars. In the past, we have explored
this connection to measure convection parameters in a number of
variable DAV white dwarf stars. Here, we present results on a
single DAV, G29-38, at different epochs with significantly
different pulsation spectra. We seek both to test our convection
measuring techniques, and understand and explore what role
convection might play in the changing pulsation spectra of this and
similar stars. |
