Hubble Ultraviolet Spectroscopy of Jupiter Trojans [PDF]

open access: yesThe Astronomical Journal, 2019
Abstract We present the first ultraviolet spectra of Jupiter Trojans. These observations were carried out using the Space Telescope Imaging Spectrograph on the Hubble Space Telescope and cover the wavelength range 200–550 nm at low resolution. The targets include objects from both of the Trojan color subpopulations (less-red and red). We

Surface Geology of Jupiter’s Trojan Asteroids

open access: yesSpace Science Reviews, 2023
AbstractThe surface geology of Jupiter’s Trojan asteroids is one of the scientific investigations of the NASALucymission. A dedicated Geology Working Group will implement these studies using primarily panchromatic and color imaging data and complement the interpretation of these data with theoretical models, such as collisional evolution models ...

Shape Models of Lucy Targets (3548) Eurybates and (21900) Orus from Disk-integrated Photometry

open access: yesThe Planetary Science Journal, 2023
We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus.

Dihydroxyterephthalate—A Trojan Horse PET Counit for Facile Chemical Recycling

open access: yesAdvanced Materials, Volume 35, Issue 21, May 25, 2023., 2023
New poly(ethylene terephthalate) (PET) plastics undergo selective hydrolysis of ester bonds through the incorporation of biobased diethyl 2,5‐dihydroxyterephthalate (DHTE) counits into polymer backbone, which facilitates low‐energy PET chemical recycling from the solid state in water.

Spectral reflectance variations of aubrites, metal‐rich meteorites, and sulfides: Implications for exploration of (16) Psyche and other “spectrally featureless” asteroids

open access: yesMeteoritics &Planetary Science, Volume 57, Issue 8, Page 1570-1588, August 2022., 2022
Abstract The 350–2500 nm reflectance spectra of five enstatite achondrites (aubrites), five metal‐rich chondrites (CBa, CBb, CH/CBb, and ungrouped), and seven sulfide mineral samples (three troilites, pyrrhotite, pentlandite, a mixture of pentlandite and chalcopyrite, and oldhamite) have been measured to search for spectral parameters that may offer ...

Abundance and importance of petrological type 1 chondritic material

open access: yesMeteoritics &Planetary Science, Volume 57, Issue 2, Page 277-301, February 2022., 2022
Abstract We review the mineralogy, petrology, and abundance of petrological type 1 extraterrestrial material. Such material has been completely altered by aqueous processing on its parent bodies. As well as the four meteorite groups that contain type 1 members (CI, CM, CR, and CY), we summarize data from the 2019 fall Flensburg and a recent reanalysis ...

A Multi‐Purpose Heliophysics L4 Mission

open access: yesSpace Weather, Volume 19, Issue 9, September 2021., 2021
Abstract The Earth‐Sun Lagrangian point 4 is a meta‐stable location at 1 AU from the Sun, 60° ahead of Earth's orbit. It has an uninterrupted view of the solar photosphere centered on W60, the Earth's nominal magnetic field connection to the Sun. Such a mission on its own would serve as a solar remote sensing observatory that would oversee the entire ...

Time and memory in Carthage

open access: yesRenaissance Studies, Volume 35, Issue 3, Page 360-385, June 2021., 2021
Abstract Rome and the Roman idea of imperium – a centring, totalizing military and legal right to rule and command obedience – looms large behind innumerable historical instances of geopolitical aspiration. Yet the story of ancient Rome and the empire it shaped does not belong to Rome alone.

Taxonomic Classification of Asteroids Using the KMTNet Multiband Photometry Data Set

open access: yesThe Planetary Science Journal, 2023
We report the multiband photometry of asteroids observed over 14 nights from 2015 December to 2017 December using the Korea Microlensing Telescope Network telescopes with the taxonomic classification of those objects. The data set contains the photometry

Imaging Lunar Craters with the Lucy Long Range Reconnaissance Imager (L’LORRI): A Resolution Test for NASA's Lucy Mission

open access: yesThe Planetary Science Journal, 2023
NASA's Lucy mission is designed to better understand the unique population of Trojan asteroids. Trojans were probably captured in Jupiter's L4 and L5 points early in the solar system's evolution and little altered since then.
