WANDs of the Black Ring
V. Pravda, A. Pravdova
Abstract
Necessary conditions for various algebraic types of the Weyl tensor are determined. These conditions are then used to find Weyl aligned null directions for the black ring solution. It is shown that the black ring solution is algebraically special, of type Ii, while locally on the horizon the type is II. One exceptional subclass - the Myers-Perry solution - is of type D.
