"Compression, Disruption, and Precession in Strong Tidal Encounters"

The abstract for my talk is: "The tidal disruption of a star by a supermassive black hole (SMBH) produces a luminous, multiwavelength flare that can probe the nuclei of quiescent galaxies. I will discuss a new analytic model we have recently introduced to study the tidal free fall phase of these events, when the disrupted star undergoes homologous vertical collapse. Using this model, we corrected a longstanding error in the literature and investigated the role of stellar spin in tidal disruption events. I will also discuss two ways in which general relativity can leave its imprint on tidal disruption flares: gravitational wave emission from the vertical bounce of the disrupted star, and the precession of accretion disks.
