Search for Magnetic Fields Among Non-Pulsators in the DAV Instability Strip
The ZZ Ceti (DAV) stars are pure hydrogen atmosphere white dwarfs presenting non-radial g mode pulsations on time scales ranging from 100 seconds to 1000 seconds. They are found in a narrow strip on the Hertzprung Russell diagram centered at 11,500 K and having a total width of 1,000 K (Bergeron et al 1995).
