The Astrophysical JournalWe report a candidate repeating tidal disruption event (TDE), AT2022sxl, found from large-field optical survey data. Two flares with a separation time of ∼7.2 yr between the two optical peaks are observed.

Lessons, open questions, and future prospects
EPJ Web of Conferences, 2012 We summarize some of the highlights of this workshop, the first of its kind dedicated to observing and modeling the tidal disruption of stars by black holes in the centers of galaxies (or star clusters).

Coalescence of Black Hole-Neutron Star Binaries
Living Reviews in Relativity, 2011 We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-

Tidal Stripping and Disruption of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1985 Tidal stripping and disruption of globular clusters may be responsible for the absence of low density clusters in the inner region of the Galaxy. We have studied these processes by integrating orbits of stars while the cluster is moving through a spherically symmetric galactic potential with constant circular velocity (Vcir =220 km/s).

Tidal capture and repeating partial tidal disruption events of giant stars
Astronomy & AstrophysicsWhen an object is scattered near a supermassive black hole (SMBH), tidal oscillations excited within it reduce its orbital energy, leading to capture by the SMBH.

Tidal Disruption Events from Stripped Stars
The Astrophysical Journal LettersObservations of tidal disruption events (TDEs) show signs of nitrogen enrichment reminiscent of other astrophysical sources such as active galactic nuclei and star-forming galaxies. Given that TDEs probe the gas from a single star, it is possible to test

Pre-peak Emission in Tidal Disruption Events
The Astrophysical JournalThe rising part of a tidal disruption event light curve provides unique insight into early emission and the onset of accretion. Various mechanisms are proposed to explain the pre-peak emission, including shocks from debris interaction and reprocessing of

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
The Astrophysical Journal LettersThe surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Underluminous tidal disruption events
Monthly Notices of the Royal Astronomical SocietyABSTRACT We have evidence of X-ray flares in several galaxies consistent with 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 a $t^{-5/3}$ decay.

Multi-messenger observations of Tidal Disruption Events
Proceedings of 27th European Cosmic Ray Symposium — PoS(ECRS), 2023 Using the Zwicky Transient Facility (ZTF) and other observatories, we have identified three candidate Tidal Disruption Events (TDEs) in spatial and temporal coincidence with high-energy neutrinos detected by IceCube: AT2019dsg, AT2019fdr and AT2019aalc. All three of these events have been shown to be able to produce high-energy neutrinos.
