Zircon (Re)crystallization During Metamorphism: Zircon Paragenesis in the Papua New Guinea Coesite Eclogite Revisited

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 7, Page 663-680, September 2025.
ABSTRACT The youngest known ultrahigh‐pressure (UHP) eclogite from Tumagabuna Island, a small island of the D'Entrecasteaux Islands chain in Papua New Guinea, exhibits zircon U–Pb age variations spanning a few million years. This age variation complicates the interpretation of the evolution of this high and ultrahigh‐pressure ([U]HP) terrane.

Survey of Cryogenic Nitrogen Thermomechanical Property Data Relevant to Outer Solar System Bodies

open access: yesEarth and Space Science, 2020
The outer Solar System has many bodies of interest that have continued to captivate the planetary science community, recently Triton, a captured Kuiper belt object (KBO) of Neptune, and Pluto.

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...

Dynamic Resonance Effects in the Statistical Distributions of Asteroids and Comets

open access: yes, 2009
Some principles in the distribution of Centaurs and the "Scattered Disk" objects, as well as the Kuiper belt objects for its semi-major axes, eccentricities and inclinations of the orbits have been investigated.

On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability

open access: yesThe Planetary Science Journal
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history.

Kuiper Belt Object Occultations: Expected Rates, False Positives, and Survey Design

open access: yes, 2009
A novel method of generating artificial scintillation noise is developed and used to evaluate occultation rates and false positive rates for surveys probing the Kuiper Belt with the method of serendipitous stellar occultations.

Detection of Close Kuiper Belt Binaries with HST WFC3

open access: yesThe Planetary Science Journal
Binaries in the Kuiper Belt are common. Here we present our analysis of the Solar System Origins Legacy Survey (SSOLS) to show that using a point-spread function (PSF)-fitting method can roughly double the number of binaries identified in that data set ...

The state of knowledge concerning the Kuiper belt [PDF]

open access: yes
The arguments for and against the idea that most short-period comets originate in the Kuiper belt are discussed. Observational constraints on the distribution of mass in the Kuiper belt are reviewed as well as a model of the physical conditions that now ...

Accretion in the Early Kuiper Belt II. Fragmentation

open access: yes, 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 =
