On the role of $\Lambda$ on accretion disks

Abstract

The dynamics of accretion disk is considered taking into account the Lense-Thirring precession in the presence of cosmological constant $\Lambda$ of Schwarzschild-de Sitter. The nodal and apsidal frequencies are obtained, and the role of $\Lambda$ is revealed in their properties, including the consequences for the Bardeen-Petterson effect.
