Density and size of comet Shoemaker–Levy 9 deduced from a tidal breakup model

  title={Density and size of comet Shoemaker–Levy 9 deduced from a tidal breakup model},
  author={J. Solem},
ALTHOUGH comets have been studied throughout most of recorded history, a detailed understanding of their internal properties is still lacking. Recent observations1 of the split comet Shoemaker–Levy 9—actually a spectacular string of cometary fragments that resulted from the tidal disruption of a single parent body as it passed close to Jupiter2–5—have therefore stimulated much interest, as they provide an unprecedented opportunity to investigate the physical properties of comets more generally6… Expand
Tidal Breakup of the Nucleus of Comet Shoemaker-Levy 9: A Review
The breakup of Comet Shoemaker-Levy 9 is discussed both in the context of splitting as a cometary phenomenon, comparing this object with other split comets, and as an event with its ownExpand
Collision of comet Shoemaker–Levy 9 with Jupiter: what did we see
In July 1994, a dramatic event took place—the collision of the Shoemaker–Levy 9 comet with Jupiter. This collision has been accompanied by a great number of various effects in the atmosphere,Expand
Evidence on sizes and fragmentation of the nuclei of comet Shoemaker-Levy 9 from Hubble Space Telescope images.
Central regions on the digital maps of 13 nuclear condensations of Comet Shoemaker-Levy 9, obtained with the Planetary Camera of the Hubble Space Telescope on January 24-25, March 28-30, and July 4,Expand
The Collision of Comet Shoemaker-Levy 9 and Jupiter: Entry and fireball models vs. observations: What have we learned?
This review attempts to give a coherent explanation of the main observations of the entry Comet Shoemaker-Levy 9 and the aftermath of the resulting explosions by using models of the tidal breakup ofExpand
Numerical modeling of the disruption of Comet D/1993 F2 Shoemaker-Levy 9 representing the progenitor by a gravitationally bound assemblage of randomly shaped polyhedra
We advance the modeling of rubble-pile solid bodies by re-examining the tidal breakup of comet Shoemaker-Levy 9, an event that occurred during a encounter with Jupiter in 1992 July. Tidal disruptionExpand
Structure and density of cometary nuclei
Understanding the nature of the cometary nucleus remains one of the major problems in solar system science. Whipples (1950) icy conglomerate model has been very successful at explaining a range ofExpand
An estimate of the Comet Shoemaker-Levy 9 fragment sizes from the debris fields
The impacts of Comet Shoemaker-Levy 9 left spots on Jupiter with diameters on the order of tens of thousands of kilometers, which have the appearance of debris fields strewn upon the Jovian cloudExpand
Impact Mechanics and Frequency of SL9-Type Events on Jupiter
Abstract A semianalytic model for the breakup of fragments of Comet Shoemaker–Levy 9 upon entry into Jupiter's atmosphere is presented. The model assumes that the impacting fragments behave as bodiesExpand
Comet Shoemaker–Levy 9 Dust Size and Velocity Distributions
Abstract Pre-impact observations of Comet Shoemaker–Levy 9 (S-L9) obtained with the Hubble Space Telescope are examined, and a model of an active, dust-producing comet is fitted to images ofExpand
Tidal Disruption of Strengthless Rubble Piles: A Dimensional Analysis
Abstract A relatively simple prescription for estimating the number of debris clumps n that form after a catastrophic tidal disruption event is presented. Following the breakup event, it is assumedExpand


Estimate of the size of comet Shoemaker-Levy 9 from a tidal breakup model
THE spectacular 'string-of-pearls' appearance of periodic comet Shoemaker-Levy 9 (1993e) and its impending encounter with Jupiter's atmosphere have caused a flurry of speculation on the likelyExpand
Origin of cometary nuclei as 'rubble piles'
COMETS are extremely fragile objects. Observations of outbursts and splitting have inspired suggestions that their nuclei are 'rubble piles', consisting of components that are weakly bonded, perhapsExpand
Are cometary nuclei primordial rubble piles?
Whipple's1 icy conglomerate model for the cometary nucleus has had considerable success in explaining a variety of cometary phenomena such as gas production rates and nongravitational forces.Expand
The Mystery of Comets
In this book, one of the world's foremost authorities on comets takes us on a voyage of discovery from the earliest speculations on the meaning of comets to his own pioneering research into both theExpand
Orbital motion, nucleus precession, and splitting of periodic Comet Brooks 2
Results of ten nongravitational orbital solutions are given for Comet Brooks 2, based on observations from the apparitions 1889-1980. The time history of the nongravitational parameters, includingExpand
Tidal disruption of solid bodies
Abstract This paper introduces three new considerations to the venerable problem of stress, strain, and breakup in solid satellites and stray bodies subject to tidal perturbations. A novel treatmentExpand
