Taxonomic Classification of Asteroids Using the KMTNet Multiband Photometry Data Set
The 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

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Geological Journal, EarlyView.Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

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.

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

The Heterogeneous Surface of Asteroid (16) Psyche
Journal of Geophysical Research: Planets, 2022 AbstractMain‐belt asteroid (16) Psyche is the largest M‐type asteroid, a class of object classically thought to be the metal cores of differentiated planetesimals and the parent bodies of the iron meteorites. de Kleer, Cambioni, and Shepard (2021, https://doi.org/10.3847/psj/ac01ec) presented new data from the Atacama Large Millimeter Array (ALMA ...

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)
X-Ray Spectrometry, EarlyView.ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Surface Modifications of a Space-weathered Ryugu Sample and the Reflectance Spectral Response
The Planetary Science JournalReflectance spectra from the surface of asteroid Ryugu, measured by the Hayabusa2 spacecraft, exhibit a metal-OH absorption at ∼2.7 μ m that is approximately half as deep as the returned samples measured in the laboratory and shifted toward longer ...

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, EarlyView.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Evidence of Possible Spectral Variability in the Patroclus–Menoetius Binary System
The Planetary Science JournalWe present new visible-wavelength spectroscopic observations of the Patroclus–Menoetius binary system in the Jupiter Trojan population. Motivated by previously published spectra from different instruments that showed evidence of significant longitudinal ...
