Abstract
We present 13 years of pulsation timing measurements of the DBV white dwarf EC20058-5234. These measurements are part of a campaign to measure the plasmon neutrino emission rate for this object. Our data is inconsistent with a simple photon plus neutrino WD cooling model. Under a certain set of assumptions, we constrain the neutrino emission rate. We describe our methodology and address the impact of our data on pulsation timing based planetary searches. [ABSTRACT FROM AUTHOR]
