  We constrain the parameterized post-Einsteinian framework with binary pulsar
observations of orbital period decay due to gravitational wave emission. This
framework proposes to enhance the amplitude and phase of gravitational waveform
templates through post-Einsteinian parameters to search for generic deviations
from General Relativity in gravitational wave data. Such enhancements
interpolate between General Relativity and alternative theory predictions, but
their magnitude must be such as to satisfy all current experiments and
observations. The data that currently constrains the parameterized
post-Einsteinian framework the most is the orbital period decay of binary
pulsars. We use such observations to place upper limits on the magnitude of
post-Einsteinian parameters, which will be critical when gravitational waves
are detected and this framework is implemented.
