Non-vanishing non-linear Static Love Number of a Class of Extremal Reissner-Nordstrom Black Holes
L. R. Gounis, A. Kehagias, G. Panagopoulos +1
We compute the tidal Love numbers for a particular axially symmetric configuration of extremal Reissner-Nordstrom geometry. By exactly solving the non-linear Einstein equations, we…

The Vanishing of the Non-linear Static Love Number of Kerr Black Holes and the Role of Symmetries
L. -R. Gounis, A. Kehagias, A. Riotto
We investigate the tidal response of Kerr black holes in four-dimensional space-times subjected to external gravitational fields. Using the Ernst formalism and Weyl coordinates, we…
