Tidal Disruptions: Applications of an Analytical Theory for Solid Bodies
Introduction: Although the theory of Roche [1] for the tidal disruption limits of orbiting satellites assumes a fluid body, a length to diameter of exactly 2.07:1, and a particular body orientation, the theory is commonly applied to the satellites of the solar system and to small asteroids and comets passing nearby a planet. Clearly these bodies are neither fluid nor generally that elongated, s...
متن کاملForming Binary Near-Earth Asteroids From Tidal Disruptions
Title of Dissertation: Forming Binary Near-Earth Asteroids From Tidal Disruptions Kevin J. Walsh, Doctor of Philosophy, 2006 Dissertation directed by: Professor Derek C. Richardson Department of Astronomy We present simulations and observations as part of a model of the binary near-Earth asteroid population. The study of binary asteroid formation includes a series of simulations of near-Earth a...
متن کاملA radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li.
The tidal disruption of a star by a supermassive black hole leads to a short-lived thermal flare. Despite extensive searches, radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) have not yet produced a conclusive detection. We present a detection of variable radio emission from a thermal TDF, which we interpret as originating from a newly launched jet. The multi...
متن کاملThe UV - bright , Slowly Declining Transient PS 1 - 11 af as a Partial Tidal Disruption Event
We present the Pan-STARRS1 discovery of the long-lived and blue transient PS1-11af, which was also detected by GALEX with coordinated observations in the near-ultraviolet (NUV) band. PS1-11af is associated with the nucleus of an early-type galaxy at redshift z=0.4046 that exhibits no evidence for star formation or AGN activity. Four epochs of spectroscopy reveal a pair of transient broad absorp...
متن کاملBinary near-Earth asteroid formation: Rubble pile model of tidal disruptions
We present numerical simulations of near-Earth asteroid (NEA) tidal disruption resulting in bound, mutually orbiting systems. Using a rubble pile model we have constrained the relative likelihoods for possible physical and dynamical properties of the binaries created. Overall 110,500 simulations were run, with each body consisting of ∼1000 particles. The encounter parameters of close approach d...
