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.

Commodity risk assessment of <i>Betula pendula</i> and <i>Betula pubescens</i> plants from the UK. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Betula pendula and B.

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 ...
