Tidal Disruption of Near-Earth Asteroids during Close Encounters with Terrestrial Planets [PDF]

open access: yesAstrophysical Journal Letters, 2023
Numerical modeling has long suggested that gravitationally bound (or so-called rubble-pile) near-Earth asteroids (NEAs) can be destroyed by tidal forces during close and slow encounters with terrestrial planets.

Fundamental scaling relationships revealed in the optical light curves of tidal disruption events [PDF]

open access: yes, 2023
We present fundamental scaling relationships between properties of the optical/UV light curves of tidal disruption events (TDEs) and the mass of the black hole that disrupted the star. We have uncovered these relations from the late-time emission of TDEs.

Uncovering Hidden Massive Black Hole Companions with Tidal Disruption Events [PDF]

open access: yesAstrophysical Journal, 2023
Dynamical perturbations from supermassive black hole (SMBH) binaries can increase the rates of tidal disruption events (TDEs). However, most previous work focuses on TDEs from the heavier black hole in the SMBH binary (SMBHB) system.

Partial stellar tidal disruption events and their rates [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
Tidal disruption events (TDEs) of stars operated by massive black holes (MBHs) will be detected in thousands by upcoming facilities such as the Vera Rubin Observatory. In this work, we assess the rates of standard total TDEs, destroying the entire star,

The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey [PDF]

open access: yesAstrophysical Journal, 2022
Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the past few decades, questions regarding the nature of the observed optical, UV,

Live to Die Another Day: The Rebrightening of AT 2018fyk as a Repeating Partial Tidal Disruption Event [PDF]

open access: yesAstrophysical Journal Letters, 2022
Stars that interact with supermassive black holes (SMBHs) can be either completely or partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of the star remains intact, and the low-density outer envelope of the ...

Dynamical Unification of Tidal Disruption Events [PDF]

open access: yesAstrophysical Journal Letters, 2022
The ∼100 tidal disruption events (TDEs) observed so far exhibit a wide range of emission properties both at peak and over their lifetimes. Some TDEs radiate predominantly at X-ray energies, while others radiate chiefly at UV and optical wavelengths ...

AT2019azh: an unusually long-lived, radio-bright thermal tidal disruption event [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Tidal disruption events (TDEs) occur when a star is destroyed by a supermassive black hole at the center of a galaxy, temporarily increasing the accretion rate onto the black hole and producing a bright flare across the electromagnetic spectrum.

Magnetically Dominated Disks in Tidal Disruption Events and Quasi-Periodic Eruptions [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
The classical radiation pressure instability has been a persistent theoretical feature of thin, radiatively efficient accretion disks with accretion rates $\sim 1 - 100\%$ of the Eddington rate.

Using the Hills Mechanism to Generate Repeating Partial Tidal Disruption Events and ASASSN-14ko [PDF]

open access: yesAstrophysical Journal Letters, 2022
Periodic nuclear transients have been detected with increasing frequency, with one such system—ASASSN-14ko—exhibiting highly regular outbursts on a timescale of 114 ± 1 days. It has been postulated that the outbursts from this source are generated by the
