The 3-4 $\mu$m Spectra of Jupiter Trojan Asteroids [PDF]
, 2016 To date, reflectance spectra of Jupiter Trojan asteroids have revealed no distinctive absorption features. For this reason, the surface composition of these objects remains a subject of speculation. Spectra have revealed, however, that the Jupiter Trojan

The Distribution of Highly Red-sloped Asteroids in the Middle and Outer Main Belt
The Planetary Science JournalRed ( S > 10%/0.1 μ m) spectral slopes are common among Centaurs and trans-Neptunian objects (TNOs) in the outer solar system. Interior to and co-orbital with Jupiter, the red ( S ∼ 10%/0.1 μ m) slopes of D-type main-belt and Jupiter Trojan asteroids are

Enhancing the Resilience of Platinum Group Metal Supply Chains: Mine to (Re)use
Sustainable Development, EarlyView.ABSTRACT Platinum group metals (PGMs) are critical elements that play a vital role in sustainable energy transition technologies such as catalysts, hydrogen production and use, and electronics. Securing a resilient PGM supply chain would support the current industrial, societal, and economic infrastructure.

Systems Research and Behavioral Science, EarlyView.ABSTRACT The short essay makes a case that a post biological world will be a devolution. Sentience is a relational process linked with the awe and wonder we experience in relation to one another and our shared habitat. The voiceless need to be protected by extending solidarity on the basis of sentience—a normative plea, but also on the basis of ...

Size and Albedo Constraints for (152830) Dinkinesh Using WISE Data
The Astrophysical Journal Letters, 2023 Probing small main-belt asteroids provides insight into their formation and evolution through multiple dynamical and collisional processes. These asteroids also overlap in size with the potentially hazardous near-Earth object population and supply the ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, EarlyView.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids
The Astrophysical JournalThe surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.

Asteroid taxonomic signatures from photometric phase curves [PDF]
, 2012 We explore the correlation between an asteroid's taxonomy and photometric phase curve using the H, G12 photometric phase function, with the shape of the phase function described by the single parameter G12. We explore the usability of G12 in taxonomic classification for individual objects, asteroid families, and dynamical groups.
