Newman-Penrose quantities as valuable tools in astrophysical relativity
arXiv:gr-qc/0411022 · doi:10.1063/1.1891553
Abstract
In this talk I will briefly outline work in progress in two different contexts in astrophysical relativity, i.e. the study of rotating star spacetimes and the problem of reliably extracting gravitational wave templates in numerical relativity. In both cases the use of Weyl scalars and curvature invariants helps to clarify important issues.
