Abstract Our current understanding of split, Jupiter-family comets is reviewed. The focus is on what recent studies of comets have told us about the nature of the splitting phenomenon. The goal is to not repeat the information given in recent reviews of split comets, but to build upon it. In particular, we discuss comets that have suffered splitting or fragmentation events in the past few years. These include comets (a) 57P/du Toit-Neujmin-Delporte, observed with a long train of fragments in… Expand

The nuclei of Jupiter family comets: A critical review of our present knowledge
Abstract Of the currently over 300 identified Jupiter family comets (JFCs), we have estimated nucleus sizes and shapes for fewer than 70 and have detailed nucleus observations arising from spacecraftExpand
CO in distantly active comets
Activity of most comets near the Sun is dominated by sublimation of frozen water, the most abundant ice in comets. Some comets, however, are active well beyond the water-ice sublimation limit of ~3Expand
Vulcanoid Asteroids and Sun-Grazing Comets – Past Encounters and Possible Outcomes
The region between 0.07 to 0.25 au from the Sun is regularly crossed by sungrazing and small perihelion distance periodic comets. This zone also supports stable orbits that may be occupied byExpand
Comet C/2011 J2 (LINEAR) nucleus splitting: Dynamical and structural analysis
Abstract After the discovery of the breakup event of comet C/2011 J2 in August 2014, we followed the primary body and the main fragment B for about 120 days in the context of a wide internationalExpand
Fragmentation Kinematics in Comet 332P/Ikeya-Murakami
We present initial time-resolved observations of the split comet 332P/Ikeya-Murakami taken using the Hubble Space Telescope. Our images reveal a dust-bathed cluster of fragments receding from theirExpand
CO and Other Volatiles in Distantly Active Comets
Activity of most comets near the Sun is dominated by sublimation of frozen water, the most abundant ice in comets. Some comets, however, are active well beyond the water-ice sublimation limit of ~3Expand
Thermal properties, sizes, and size distribution of Jupiter-family cometary nuclei
We present results from SEPPCoN, an on-going Survey of the Ensemble Physical Properties of Cometary Nuclei. In this report we discuss mid-infrared measurements of the thermal emission from 89 nucleiExpand
Evidence for geologic processes on comets
Spacecraft missions have resolved the nuclei of six periodic comets and revealed a set of geologically intriguing and active small bodies. The shapes of these cometary nuclei are dominantly bilobateExpand
Physical Characterization of the 2017 December Outburst of the Centaur 174P/Echeclus
The Centaurs are the small solar system bodies intermediate between the active inner solar system Jupiter Family Comets and their inactive progenitors in the trans-Neptunian region. Among theExpand
Surface geomorphology of Jupiter Family Comets: A geologic process perspective
Abstract Recent spacecraft encounters with Jupiter Family Comets have revealed markedly diverse surface morphologies: Wild 2 is dominated by steep-walled and flat-floored depressions, Tempel 1 isExpand

COMET SPLITTING - OBSERVATIONS AND MODEL SCENARIOS
Splitting events affect cometary nuclei to a different level of severity ranging from complete disruption of the nucleus (e.g., C/1999 S4 LINEAR) to separation of major fragments (e.g.,Expand

Abstract The large numbers of nucleus fragments observed are a spectacular illustration of the process of cascading fragmentation in progress, a concept introduced to interpret the properties of theExpand
174P/Echeclus: a strange case of outburst
Context. More than ten Centaurs are now known to have cometary activity at large heliocentric distance (i.e. $\simeq$5-13 AU). Among these objects, 174P/Echeclus which showed cometary activity at 13Expand
Organic volatiles in comet 73P-B/Schwassmann-Wachmann 3 observed during its outburst : A clue to the formation region of the jupiter-family comets
We report the chemical composition of organic molecules in fragment B of comet 73P/Schwassmann-Wachmann 3 (SW3). Comet SW3 is a Jupiter-family comet that split into three fragments during its 1995Expand
The problem of split comets in review
Cometary splitting is investigated from the dynamical and physical standpoints. A simple two-parameter model is proposed in which the rate of recession of the fragments is determined by the momentumExpand
Deep Impact and the Origin and Evolution of Cometary Nuclei
The Deep Impact mission revealed many properties of comet Tempel 1, a typical comet from the Jupiter family in so far as any comet can be considered typical. In addition to the properties revealed byExpand
Using Cometary Activity to Trace the Physical and Chemical Evolution of Cometary Nuclei
Historically, minor bodies are classified as comets based on observations of “activity,” which refers to the appearance of dust and gas around the nucleus. While cometary activity has been observedExpand
First results of the integration of motion of short-period comets over 800 years
All the known short-period comets have been followed by numerical integration over a time span of 821 years, from 1585 to 2406. A preliminary survey of the results of these integrations has shownExpand
