Probing Massive Scalar/Vector Fields with Binary Pulsars
Brian C. Seymour, Kent Yagi
Precision tests of general relativity can be conducted by observing binary pulsars. Theories with massive fields exist to explain a variety of phenomena from dark energy to the str…
Probing Massive Scalar Fields from a Pulsar in a Stellar Triple System
Brian C. Seymour, Kent Yagi
Pulsar timing observations precisely test general relativity. Recently, the hierarchical triple system PSR J0337+1715 has placed new constraints on the existence of a fifth force f…
Future Prospects for Probing Scalar-Tensor Theories with Gravitational Waves from Mixed Binaries
Zack Carson, Brian C. Seymour, Kent Yagi
The extreme-gravity collisions of binaries with one black hole and one neutron star provide for excellent tests of general relativity. We here study how well one can constrain theo…
Testing General Relativity with Black Hole-Pulsar Binaries
Brian C. Seymour, Kent Yagi
Binary pulsars allow us to carry out precision tests of gravity and have placed stringent bounds on a broad class of theories beyond general relativity. Current and future radio te…
