Tidal disruption events (TDEs) offer a unique opportunity to study a single supermassive black hole (SMBH) under feeding conditions that change over timescales of days to months. However, the primary mechanism for generating luminosity during the flares remains debated. Despite the increasing number of observed TDEs, it is unclear whether most of the energy in the initial flare comes from accretion near the gravitational radius or from circularizing debris at larger distances from the SMBH. The… Expand

Tidal disruption event demographics
We survey the properties of stars destroyed in TDEs as a function of BH mass, stellar mass and evolutionary state, star formation history and redshift. For Mbh<10^7Msun, the typical TDE is due to aExpand
Tidal Disruptions of Main-sequence Stars. I. Observable Quantities and Their Dependence on Stellar and Black Hole Mass
This paper introduces a series of papers presenting a quantitative theory for the tidal disruption of main sequence stars by supermassive black holes. Using fully general relativistic hydrodynamicsExpand
A Comment on the Radiative Efficiency of AGN
A recent study of the accretion efficiency of the PG sample AGN, based on the thin accretion disk emission model, finds the accretion radiative efficiency is correlated with the black hole mass (etaExpand

Stellar TDEs with Abundances and Realistic Structures (STARS): Library of Fallback Rates
We present the STARS library, a grid of tidal disruption event (TDE) simulations interpolated to provide the mass fallback rate ($dM/dt$) to the black hole for a main-sequence star of any stellarExpand

Implications from Late-time X-Ray Detections of Optically Selected Tidal Disruption Events: State Changes, Unification, and Detection Rates
Using Chandra X-ray observations we detect three out of four optically-selected tidal disruption events (TDEs) 4-9 years after their discovery. The spectrum of PTF09axc is consistent with a power lawExpand
On the Diversity of Fallback Rates from Tidal Disruption Events with Accurate Stellar Structure
The tidal disruption of stars by supermassive black holes (SMBHs) can be used to probe the SMBH mass function, the properties of individual stars, and stellar dynamics in galactic nuclei. UpcomingExpand
Partial Stellar Disruption by a Supermassive Black Hole: Is the Light Curve Really Proportional to t(-9/4)?
The tidal disruption of a star by a supermassive black hole, and the subsequent accretion of the disrupted debris by that black hole, offers a direct means to study the inner regions ofExpand
The Tidal Disruption of Sun-like Stars by Massive Black Holes
We present the first simulations of the tidal disruption of stars with realistic structures and compositions by massive black holes (BHs). We build stars in the stellar evolution code MESA andExpand
