Simultaneous Sizing of a Rocket Family with Embedded Trajectory Optimization [PDF]
arXiv, 2023 A sizing procedure for a rocket family capable of fulfilling multiple missions considering the commonality is presented. The procedure aims to take full advantage of sharing a common part across multiple rockets whose payload capability differs entirely, ultimately leading to cost savings in designing a rocket family.

Photometric Confirmation and Characterization of the Ennomos Collisional Family in the Jupiter Trojans [PDF]
AJ, 165, 15 (2023), 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 through spectral characterization.

Potential Themis Family Asteroid Contribution to the Jupiter-Family Comet Population [PDF]
Astronomical Journal, 2020 Recent dynamical analyses suggest that some Jupiter family comets (JFCs) may originate in the main asteroid belt instead of the outer solar system. This possibility is particularly interesting given evidence that icy main-belt objects are known to be present in the Themis asteroid family.

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 have recreated the Centaur/JFC conversion, but the mechanism behind that process remains poorly ...

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).

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 ...

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).
