Constraints on parameterized post-Einstenian framework from binary pulsar observations*

The parameterized post-Einsteinian (ppE) formalism was proposed to search for generic deviations from general relativity. In this talk we present constraints on the ppE framework obtained from binary pulsar observations. We use measurements of the  orbital period decay and post-Keplerian parameters to put bounds on the magnitude of the ppE parameters. Gravitational wave data from coalescing binaries can also be used to do a systematic Bayesian study of the ppE framework and the bounds that we have obtained can be used as an informative prior for such an analysis.
