Semimajor-axis Jumps as the Activity Trigger in Centaurs and High-perihelion Jupiter-family Comets [PDF]
Astrophysical Journal Letters, 2023 We present a dynamical study of 39 active Centaurs and 17 high-perihelion (q > 4.5 au) Jupiter-family comets (JFCs) with a focus on investigating recent orbital changes as potential triggers for comet-like activity. We have identified a common feature in

Phase Curves of Kuiper Belt Objects, Centaurs, and Jupiter-family Comets from the ATLAS Survey [PDF]
The Planetary Science Journal, 2023 The Kuiper Belt objects (KBOs), the Centaurs, and the Jupiter-family comets (JFCs) form an evolutionary continuum of small outer solar system objects, and their study allows us to gain insight into the history and evolution of the solar system. Broadband

Thermal Processing of Jupiter-family Comets during Their Chaotic Orbital Evolution [PDF]
Astrophysical Journal, 2022 Evidence for cometary activity beyond Jupiter’s and Saturn’s orbits—such as that observed for Centaurs and long-period comets—suggests that the thermal processing of comet nuclei starts long before they enter the inner solar system, where they are ...

The Gateway from Centaurs to Jupiter-family Comets: Thermal and Dynamical Evolution [PDF]
Astrophysical Journal, 2022 It was recently proposed that there exists a “gateway” in the orbital parameter space through which Centaurs transition to Jupiter-family comets (JFCs).

Photometric Confirmation and Characterization of the Ennomos Collisional Family in the Jupiter Trojans [PDF]
Astronomical Journal, 2022 Collisional families offer a unique window into the interior composition of asteroid populations. Previous dynamical studies of the Jupiter Trojans have uncovered a handful of potential collisional families, two of which have been subsequently confirmed ...

Implications for the Collisional Strength of Jupiter Trojans from the Eurybates Family [PDF]
Astronomical Journal, 2021 In this work, we model the collisional evolution of the Jupiter Trojans and determine under which conditions the Eurybates-Queta system survives. We show that the collisional strength of the Jupiter Trojans and the age of the Eurybates family and by ...

New Active Jupiter Family Comet 2008 QZ44: a Discovery with Citizen Science
Research Notes of the AAS, 2023 We report our discovery of cometary activity in the form of a diffuse tail associated with minor planet 2008 QZ44 during two previous orbits: 2008 and 2017. This finding was prompted in part by Active Asteroids, our Zooniverse-hosted NASA Partner Citizen

The Transformation of Centaurs into Jupiter-family Comets
Astrophysical Journal, 2022 Centaurs are an ephemeral class of objects that can evolve into Jupiter-family comets (or JFCs) due to gravitational perturbations from the giant planets.
