In this paper we will review some recent developments in the theory of Tidal Disruption Events (TDE). In particular, we discuss how recent work has led to a reconsideration of the time evolution of the debris of the disrupted star, which in turn determines the lightcurve of the event. We discuss the efforts being currently made to understand how an accretion disc forms around these objects. Finally, we discuss whether we can expect these systems to undergo rigid precession as a consequence of the Lense-Thirring torques produced by a spinning black hole.

Abstract
In this paper we will review some recent developments in the theory of Tidal Disruption Events (TDE). In particular, we discuss how recent work has led to a reconsideration of the time evolution of the debris of the disrupted star, which in turn determines the lightcurve of the event. We discuss the efforts being currently made to understand how an accretion disc forms around these objects. Finally, we discuss whether we can expect these systems to undergo rigid precession as a consequence of the Lense-Thirring torques produced by a spinning black hole.
