Underluminous tidal disruption events [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We have evidence of X-ray flares in several galaxies consistent with a a star being tidally disrupted by a supermassive black hole (MBH). If the star starts on a nearly parabolic orbit relative to the MBH, one can derive that the fallback rate follows ...

Seventeen Tidal Disruption Events from the First Half of ZTF Survey Observations: Entering a New Era of Population Studies [PDF]
Astrophysical Journal, 2020 While tidal disruption events (TDEs) have long been heralded as laboratories for the study of quiescent black holes, the small number of known TDEs and uncertainties in their emission mechanism have hindered progress toward this promise.

Cooling Envelope Model for Tidal Disruption Events [PDF]
Astrophysical Journal Letters, 2022 We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris streams promptly and rapidly circularize (on the orbital period of the most ...

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes
The Astrophysical Journal Letters, 2023 Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

A simple and accurate prescription for the tidal disruption radius of a star and the peak accretion rate in tidal disruption events [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 A star destroyed by a supermassive black hole (SMBH) in a tidal disruption event (TDE) enables the study of SMBHs. We propose that the distance within which a star is completely destroyed by a SMBH, defined rt, c, is accurately estimated by equating ...

AT 2020wey and the class of faint and fast tidal disruption events [PDF]
Astronomy & Astrophysics, 2022 We present an analysis of the optical and UV properties of AT 2020wey, a faint and fast tidal disruption event (TDE) at 124.3 Mpc. The light curve of the object peaked at an absolute magnitude of $M_{g} = -17.45$ mag and a maximum bolometric luminosity ...

Extremely Relativistic Tidal Disruption Events
The Astrophysical Journal Letters, 2023 Extreme tidal disruption events (eTDEs), which occur when a star passes very close to a supermassive black hole, may provide a way to observe a long-sought general relativistic effect: orbits that wind several times around a black hole and then leave ...

On the Impact of Relativistic Gravity on the Rate of Tidal Disruption Events [PDF]
Astrophysical Journal, 2022 The tidal disruption of stars by supermassive black holes (SMBHs) probes relativistic gravity. In the coming decade, the number of observed tidal disruption events (TDEs) will grow by several orders of magnitude, allowing statistical inferences of the ...

Tidal Disruption Events from Eccentric Orbits and Lessons Learned from the Noteworthy ASASSN-14ko [PDF]
Astrophysical Journal, 2022 Stars grazing supermassive black holes (SMBHs) on bound orbits may survive tidal disruption, causing periodic flares. Inspired by the recent discovery of the periodic nuclear transient ASASSN-14ko, a promising candidate for a repeating tidal disruption ...

A Model for the Possible Connection Between a Tidal Disruption Event and Quasi-periodic Eruption in GSN 069 [PDF]
Astrophysical Journal, 2022 Quasi-periodic eruptions (QPEs) are found in the center of five galaxies, where a tidal disruption event (TDE)-like event has been reported in GSN 069, which occurred a couple of years before the QPEs.
