Resonant relaxation and the warp of the stellar disc in the galactic centre.

KOCSIS B. and TREMAINE S.

Abstract (from CDS):

Observations of the spatial distribution and kinematics of young stars in the Galactic Centre can be interpreted as showing that the stars occupy one, or possibly two, discs of radii ∼0.05-0.5 pc. The most prominent (`clockwise') disc exhibits a strong warp: the normals to the mean orbital planes in the inner and the outer third of the disc differ by ∼60°. Using an analytical model based on Laplace-Lagrange theory, we show that such warps arise naturally and inevitably through vector resonant relaxation between the disc and the surrounding old stellar cluster.
