Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.Relative weathering indices and three‐dimensional fabric analyses demonstrate allochthonous emplacement of the Hickory Run Boulder Field via periglacial mass movement. Spatially coherent trends confirm a time‐transgressive surface formed under Pleistocene permafrost conditions, with tributary‐like integration of clasts from a secondary boulder field ...

The small numbers of large Kuiper belt objects [PDF]
, 2013 We explore the brightness distribution of the largest and brightest (m(R) < 22) Kuiper Belt Objects (KBOs). We construct a luminosity function of the dynamically excited or hot Kuiper Belt (orbits with inclinations >5°) from the very brightest to m(

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution
AGU Advances, Volume 6, Issue 6, December 2025.Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

The Inner Kernel of the Classical Kuiper Belt
The Astrophysical Journal LettersThe “kernel” of the classical Kuiper Belt was discovered by Petit et al. as a visual overdensity of objects with low ecliptic inclinations and eccentricities at semimajor axes near ∼44 au.

Accretion in the Early Kuiper Belt II. Fragmentation
, 1999 We describe new planetesimal accretion calculations in the Kuiper Belt that include fragmentation and velocity evolution. All models produce two power law cumulative size distributions, N_C propto r^{-q}, with q = 2.5 for radii less than 0.3-3 km and q =

Collisional Grooming Models of the Kuiper Belt Dust Cloud [PDF]
, 2010 We modeled the 3-D structure of the Kuiper Belt dust cloud at four different dust production rates, incorporating both planet-dust interactions and grain-grain collisions using the collisional grooming algorithm.

Tracking Sediment Mixing Along the Lower Danube River From the Carpathians to the Black Sea
Terra Nova, Volume 37, Issue 6, Page 413-420, December 2025.ABSTRACT We use detrital zircon U–Pb geochronology as a sediment provenance tracer in modern river sands to better understand how tectonic, climatic, and anthropogenic processes modulate sediment transport dynamics of the Carpathians to the Black Sea source to sink system.
