Title: Measuring Convection on the Surface of a Pulsating White Dwarf
Abstract:
Through a coordinated network of world-wide observatories, we
propose to take advantage of advances in pulsation theory to empirically
determine the physical properties of convection in a pulsating hydrogen
atmosphere white dwarf star (DAV). We will use observed nonlinear pulse
shapes of the pulsating white dwarf WDJ1524-0030, combined with accurate
frequency, amplitude, and phase information, to directly probe the
nature of its convection zone.
