In their most generic configuration, compact objects in a binary system are subject to interactions between the spin and the orbital angular momenta. These interactions give rise to precessional effects that add rich structure to the emitted gravitational waveforms. We study this spin-induced structure with an emphasis on extracting the information it encodes. In particular, we construct gravitational wave models that accurately capture spin-precessional effects. We then use them to study how much information relevant to astrophysics and nuclear physics we can extract from future observations of gravitational waves from compact binary coalescences.enGravitational wavesMultiple starsDissertationCopyright 2016 by Katerina Chatziioannou
