The Contribution of Dwarf Planets to the Origin of Jupiter Family Comets [PDF]

Astronomical Journal, 2019
We explore the long-term evolution of a bias-free orbital representation of the cometary nuclei (with diameters above 2 km) of the Kuiper Belt, using the so-called L7 synthetic model from CFEPS, which consists of three dynamical subpopulations: the ...

The Relationship between Centaurs and Jupiter Family Comets with Implications for K-Pg-type Impacts [PDF]

Monthly notices of the Royal Astronomical Society, 2019
Centaurs—icy bodies orbiting beyond Jupiter and interior to Neptune—are believed to be dynamically related to Jupiter Family Comets (JFCs), which have aphelia near Jupiter's orbit, and perihelia in the inner Solar System. Previous dynamical simulations

Rotation of cometary nuclei: new light curves and an update of the ensemble properties of Jupiter-family comets [PDF]

, 2017
We report new lightcurves and phase functions for nine Jupiter-family comets (JFCs). They were observed in the period 2004-2015 with various ground telescopes as part of the Survey of Ensemble Physical Properties of Cometary Nuclei (SEPPCoN) as well as ...

New Jupiter and Saturn Satellites Reveal New Moon Dynamical Families

Research Notes of the AAS, 2023
Tens of new moons around both Jupiter and Saturn have been announced on Minor Planet Electronic Circulars (MPECs) in late 2022 and early 2023. Jupiter now has 95 and Saturn 146 confirmed moons.

Discovery of Jupiter Family Comet 2011 UG104 Through AI Enhanced Citizen Science

Research Notes of the AAS
We report the discovery of cometary activity from minor planet 2011 UG104, which we classify as a Jupiter Family Comet (JFC). This discovery was aided by our Artificial Intelligence (AI) classification system: TailNet.

Ceres: Organic‐Rich Sites of Exogenic Origin?

AGU Advances, Volume 6, Issue 1, February 2025.
Abstract Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara craters. The origin of organics, either endogenic or exogenic, in these fresh exposures is still

Evidence for Magnetically‐Driven Accretion in the Distal Solar System

AGU Advances, Volume 5, Issue 6, December 2024.
Abstract Paleomagnetic measurements of meteorites indicate that magnetic fields existed in the inner solar nebula capable of driving accretion at rates similar to those observed for young stellar objects with protoplanetary disks. However, the field strength in the solar system beyond ∼7 astronomical units (AU) and its role in accretion remain poorly ...

Why are Jupiter-family comets active and asteroids in cometary-like orbits inactive? [PDF]

, 2016
Context: Surveys in the visible and near-infrared spectral range have revealed the presence of low-albedo asteroids in cometary like orbits (ACOs). In contrast to Jupiter family comets (JFCs), ACOs are inactive, but possess similar orbital parameters ...
