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

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

Citizen Science Discovery of a Recurrently Active Jupiter-Family Comet: (551023) 2012 UQ192
Research Notes of the AAS, 2023 We have discovered evidence of cometary activity originating from (551023) 2012 UQ192 (alternately designated 2019 SN40), which we dynamically classify as a Jupiter Family Comet (JFC).

Activity in Centaur-like Jupiter-family Comet 2023 RN3
Research Notes of the AAS, 2023 We present multi-filter observations of Centaur-like Jupiter-family comet 2023 RN3 conducted as part of the Las Cumbres Observatory Outbursting Objects Key Project, as well as analysis of archival data in which 2023 RN3 was expected to be present.

Mars-Crossing Minor Planet 2018 VL10: a Jupiter-family Comet Discovery via Citizen Science
Research Notes of the AAS, 2023 We announce the discovery of cometary activity emitting from minor planet 2018 VL10 in Dark Energy Camera images spanning from UT 2018 December 31 to UT 2019 March 3. The activity was identified by volunteers of our NASA Partner program Active Asteroids,
