Gravitational Wave source Modelling 1: Basic formalism In this lecture I will present the so-called quadrupole formalism for describing the gravitational wave emission from a neutron star. Within this formalism, General Relativity is treated as a correction to Newtonian physics. I will sketch out the key formulae, and show how they lead to some well known results for the gravitational wave amplitude and luminosity of a source. Insights and formulae from this formalism provide a great deal of our intuition as to how compact objects emit gravitational waves, and are made use of in other lectures in this school.
