Abstract:
Writing the metric of an asymptotically flat spacetime in Bondi coordinates
provides an elegant way of formulating the Einstein equation as a
characteristic value problem. In this setting, we find that a specific class of
asymptotically flat spacetimes, including stationary solutions, contains a
Maxwell gauge field as free data. Choosing this gauge field to correspond to
the Dirac monopole, we derive the Taub-NUT solution in Bondi coordinates.
