  author={Lior M. Burko and Gaurav Khanna and Subir Sabharwal},
It has been shown recently that extreme Reissner-Nordstrom black holes perturbed by a minimally coupled, free, massless scalar field have permanent scalar hair. The hair - defined by a certain expression at future null infinity - approaches a conserved charge calculated at the black hole's event horizon inversely in time. We generalize this newly discovered hair also for extreme Kerr black holes. We study the behavior of nearly extreme black hole hair as a transient phenomenon. For nearly… CONTINUE READING
