The Largest Kuiper Belt Objects

, 2008
While for the first decade of the study of the Kuiper belt, a gap existed between the sizes of the relatively small and faint Kuiper belt objects (KBOs) that were being studied and the largest known KBO.

Spectral Characterization of the Organic- and Methanol-rich Cliff-type Trans-Neptunian Objects

The Astronomical Journal
Trans-Neptunian objects (TNOs) harbor pristine materials from the early solar system. The James Webb Space Telescope offers major insights into the spectral classification of these small bodies.

Piecing the barcoding puzzle of Palearctic water frogs (Pelophylax) sheds light on amphibian biogeography and global invasions

Global Change Biology, Volume 30, Issue 3, March 2024.
By revisiting three decades of molecular data, we retraced the evolution and mapped the diversity of Pelophylax water frogs, a famous group of Eurasian amphibians. The results highlight the Paratethys Paleo‐sea as a major driver of diversification, implement a new timetree validation approach, emphasize the rare ability of lineages to hybridize despite

Cosmic Ray Mantle Visibility on Kuiper Belt Objects

, 2006
Optically red objects constitute the dynamically cold, old component of the Classical Kuiper Belt (40 - 47 AU) with heliocentric orbits of low eccentricity and inclination.

Rotational Study of 5:3 and 7:4 Resonant Objects within the Main Classical Trans-Neptunian Belt

The Planetary Science Journal
The 5:3 and 7:4 mean motion resonances of Neptune are at 42.3 and 43.7 au, respectively, and overlap with objects in the classical trans-Neptunian belt (Kuiper Belt).

A Correlation between Inclination and Color in the Classical Kuiper Belt [PDF]

, 2002
We have measured broadband optical BVR photometry of 24 classical and scattered Kuiper belt objects (KBOs), approximately doubling the published sample of colors for these classes of objects. We find a statistically significant correlation between object

The Structure of the Kuiper Belt from Observations and Simulations: Understanding our Solar System's Architecture

, 2017
There are currently close to 3000 known Kuiper Belt Objects. Their orbits show that the Kuiper Belt contains rich dynamical structures. By carefully recording telescope pointings, tracking biases, and detection biases, as has been done for a handful of

On Error Estimates for Hapke Photometric Model Parameters from Disk-integrated Phase Curves of Airless Planetary Bodies

The Planetary Science Journal
The Hapke bidirectional reflectance model is widely used to analyze photometric observations of planetary surfaces. When fitting disk-integrated data, nonuniqueness concerns arise if observations lack sufficient phase angle coverage to constrain the ...

Retention of a Primordial Cold Classical Kuiper Belt in an Instability-Driven Model of Solar System Formation [PDF]

, 2011
The cold classical population of the Kuiper Belt exhibits a wide variety of unique physical characteristics, which collectively suggest that its dynamical coherence has been maintained throughout the solar system's lifetime. Simultaneously, the retention

Numerical Investigation of the Cohesive Strength Regime of the Bilobated Arrokoth after the Sky-crater-forming Impact Event

The Planetary Science Journal
In 2019, NASA’s New Horizons mission, using the Long Range Reconnaissance Imager, revealed Arrokoth’s bilobated shape and a large impact-crater-like region (“Sky”) on the small lobe, which is ∼7 km wide and ∼1 km deep. Given that this depression takes up
