JWST Spectroscopy of a Blue Binary Cold Classical Kuiper Belt Object
The Planetary Science JournalWe present observations of two binary systems within the cold classical region of the Kuiper Belt—2001 XR254 and 2016 BP81—obtained with the JWST Near-Infrared Spectrograph.

Quantitative targets for leopard conservation in sub‐Saharan Africa
Journal 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 ...

The Tidal Potential of a Homogeneous Torus with an Elliptical Section of the Sleeve
Open Astronomy, 2016 In this paper the problem of the tidal potential of a homogeneous gravitating torus with an elliptical cross-section sleeve is solved. In particular, the potentials in analytical form in the vicinity of the center of the torus and its external region are

Calculating the Area within the Orbit of Arrokoth
Undergraduate Journal of Mathematical Modeling: One + Two, 2020 The area within the orbit of the Kuiper Belt object (KBO) Arrokoth (or 2014MU69) is approximated using the corresponding ellipse. The fact that the Sun lies at a focus of the ellipse is of interest.

Global Occurrence of Solitary Waves in the Martian Magnetosphere
Geophysical 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?
Journal 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.

, 2008 International audienceNear-symmetric binaries - i.e., binaries with roughly samesized partners - appear to dominate the known population of binaries in the Kuiper-belt. Herein the mass- and sizeratio distributions, as well the resulting orbit properties,

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...
