Trajectory Optimization Methods for Low-Thrust Kuiper Belt Flyby Missions

open access: yes, 2023
The Kuiper belt is one of the last mostly unexplored regions in the Solar System. Exploration of the Kuiper belt can greatly increase humanity's understanding of the Solar System's formation and evolution. The use of low-thrust propulsion for Kuiper belt

The Albedo, Size, and Density of Binary Kuiper Belt Object (47171) 1999 TC36 [PDF]

open access: yes, 2006
We measured the system-integrated thermal emission of the binary Kuiper Belt object (47171) 1999 TC36 at wavelengths near 24 and 70 μm using the Spitzer Space Telescope. We fit these data and the visual magnitude using both the standard thermal model and

Untangling the Copy Number Variation at the Basis of Belted Phenotypes in Cattle Using Long‐Read Sequencing

open access: yesAnimal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT The belted phenotype in cattle, a distinctive white belt across the midsection observed in breeds such as the Dutch Belted and Belted Galloway, is caused by a copy number variant (CNV) upstream of TWIST2, a gene involved in melanocyte development.

Detection of Methane on Kuiper Belt Object (50000) Quaoar [PDF]

open access: yes, 2006
The near-infrared spectrum of (50000) Quaoar obtained at the Keck Observatory shows distinct absorption features of crystalline water ice, solid methane and ethane, and possibly other higher order hydrocarbons. Quaoar is only the fifth Kuiper belt object

The Bimodal Color Distribution of Small Kuiper Belt Objects* [PDF]

open access: yesThe Astronomical Journal, 2017
Abstract We conducted a two-night photometric survey of small Kuiper Belt objects (KBOs) near opposition using the wide-field Hyper Suprime-Cam instrument on the 8.2 m Subaru Telescope. The survey covered about 90 deg2 of sky, with each field imaged in the g and i bands.

Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1950-1964, August 2026.
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Rotation and Mutual Eclipse Events Season in the Kuiper Belt: (524366) 2001 XR254

open access: yesThe Astronomical Journal
(524366) 2001 XR _254 is a dynamically cold classical Kuiper Belt object that is a nearly equal-sized wide binary whose upcoming mutual event season makes it a particularly valuable target for physical characterization.

Quantitative targets for leopard conservation in sub‐Saharan Africa

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
By integrating density modelling with habitat suitability, we provide a decision‐support framework for leopard conservation across sub‐Saharan Africa. The results identify where conservation investment is most likely to yield demographic gains, support the re‐evaluation of national hunting quotas against sustainable offtake thresholds and offer an ...

Global Occurrence of Solitary Waves in the Martian Magnetosphere

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.
