The Inclination Distribution of the Kuiper Belt [PDF]

, 2001
We develop a general method for determining the unbiased inclination distribution of the Kuiper belt using only the inclination and latitude of discovery of known Kuiper belt objects (KBOs).

A Broad Set of Solar and Cosmochemical Data Indicates High C-N-O Abundances for the Solar System

The Astrophysical Journal
We examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper Belt objects (KBOs) and CI chondrites.

Recently Identified Mesoproterozoic Strata in South‐Central Idaho Document Late‐Stage Rifting of the Nuna Supercontinent in Western Laurentia

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract Sedimentary basins are valuable archives of tectonic processes involved in continental rifting. The northern Rocky Mountains preserve the Belt Supergroup, one of the most complete records of Mesoproterozoic strata on Earth; however, debate remains about its tectonic origin.

Prominent Mid-infrared Excess of the Dwarf Planet (136472) Makemake Discovered by JWST/MIRI Indicates Ongoing Activity

The Astrophysical Journal Letters
We report on the discovery of a very prominent mid-infrared (18–25 μ m) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the Mid-Infrared Instrument of the James Webb Space Telescope, along with previous ...

Icy ocean worlds, plumes, and tasting the water

Meteoritics &Planetary Science, Volume 59, Issue 6, Page 1385-1406, June 2024.
Abstract This paper considers how space missions that fly through the plumes known, or suspected, to erupt naturally from some icy ocean worlds (IOW), such as Enceladus, or that aim to intercept icy ejecta from impact cratering processes on such bodies can sample the water and ice within the plumes.

Long-Term Dynamics And The Orbital Inclinations Of The Classical

, 2007
We numerically integrated the orbits of 1458 particles in the region of the classical Kuiper belt (41 AU a 47 AU) to explore the role of dynamical instabilities in sculpting the inclination distribution of the classical Kuiper belt objects (KBOs).

Photometry of Kuiper belt object (486958) Arrokoth from New Horizons LORRI [PDF]

, 2021
On January 1st 2019, the New Horizons spacecraft flew by the classical Kuiper belt object (486958) Arrokoth (provisionally designated 2014 MU69), possibly the most primitive object ever explored by a spacecraft.

Dynamical Studies of the Kuiper Belt and the Centaurs

, 2013
The Kuiper belt is a population of small bodies located outside Neptune's orbit. The observed Kuiper belt objects (KBOs) can be divided into several subclasses based on their dynamical structure.

Challenge in Arrokoth’s Single Merger to Achieve the Shape’s Principal Axis Configuration

The Planetary Science Journal
The cold-classical Kuiper Belt Object 486958 Arrokoth is a contact binary composed of two flattened lobes, Weeyo and Wenu, closely aligned along their principal axes, despite each lobe having a highly irregular shape.

Neogene‐Recent Reactivation of Pre‐Existing Faults in South‐Central Vietnam, With Implications for the Extrusion of Indochina

Tectonics, Volume 43, Issue 4, April 2024.
Abstract Vietnam contains complex faults coupled with a diffuse igneous province that has been active since the mid‐Miocene. However, existing fault maps demonstrate little consensus over the location of Neogene basalt flows and relative ages of mapped faults, which complicates interpretations of tectonic model for the evolution of Indochina.
