ESTETIKA

Abstract: In this article some scholars and their perspective on aesthetic are presented, from the beginning of the term to the 20th century (Contemporary aesthetic), althought postmodern aesthetic is not include. The devoloping phases og aesthetic. The Implementation follow the need of aesthetic, wether it is for an evaluation or for other needs. For example, it may be use for the shake of knowledge, to criticize, to deconstruct, and recontruct the work of art. This presentation is hopefully understood and can be implemanted according to the need of aesthetic philosophy. Key word : Filsafat, Estetika dan Sejarah

Kerr-Sen-Taub-NUT spacetime and circular geodesics

We present a novel solution obeying classical equation of motion in the low energy limit of heterotic string theory. The solution represents a rotating mass with electric charge and gravitomagnetic monopole moment. The corresponding conserved charges are discussed. We also study the test body circular equatorial motions in the spacetime.Comment: 20 pages, 7 figures;V3, minor revisions; V2, refs adde

Pair production of scalars around near-extremal Kerr-Sen black holes

We investigate the charged scalar pair production near the horizon of a near-extremal Kerr-Sen black holes. The condition for pair production to occur has relation to the violation of Breitenlohner-Freedman bound in an AdS$_2$ space. The method employed in this work has been used to show the pair production in the near-horizon of a near-extremal Kerr-Newman black hole and its non-rotating case as well. We also discuss the static limit of our result.Comment: 16 pages, 1 figur
