Specifically, we consider the time evolution of horizon penetrating scalar and gravitational perturbations with compact support on near-extremal Reissner-Nordstr\u00f6m and Kerr. We do this by numerically solving the Teukolsky equation and determining the Aretakis charge values on the horizon and at a finite distance from the black hole. We demonstrate that these values are no longer strictly conserved in the nonextremal case; however, their decay rate can be arbitrarily slow as the black hole approaches extremality allowing for the possibility of their observation as a\u00a0<em>transient<\/em>\u00a0hair.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kevin&#8217;s MS thesis paper just got published and can be found here: Phys.
