New features in the structure of the classical Kuiper Belt

, 2016
International audienceWe report fascinating new dynamical structures emerging from a higher precision view of the classical Kuiper belt (the plentiful non-resonant orbits with semimajor axes in roughly the a=35-60 au range).

heliostack: A Novel Approach to Minor Planet Discovery

The Planetary Science Journal
The study of faint solar system objects is a promising avenue for understanding the origin and evolution of planetary systems. However, such objects are difficult to detect in conventional surveys.

The DECam Ecliptic Exploration Project (DEEP). VI. First Multiyear Observations of Trans-Neptunian Objects

The Astronomical Journal
We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discoveries.

The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI

Journal of Geophysical Research: Planets, Volume 129, Issue 10, October 2024.
Abstract Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid‐Infrared Instrument (4.9–27.9 μ ${\upmu }$m) in July and August 2022. These observations took place alongside a suite of visual and infrared observations from; Hubble, JWST/NIRCam, Very Large Telescope/VISIR and amateur observers which provided both spatial ...

Understanding the Origin of Planetary Systems: Studying the Kuiper Belt and the Dynamics of Planet Formation [PDF]

, 2009
This thesis presents theoretical and observational studies pertaining to the early solar system, planet formation and extrasolar planets. First, we explore the dynamics of protoplanet formation. We find that the growth of protoplanets may be dominated

The Edges of Planetary Systems: Falling Off the Kuiper Cliff in a Dissipating Gas Disk

The Astrophysical Journal
Probably the last planetesimals to have formed from dust in the solar nebula are cold classical Kuiper Belt Objects (CCKBOs). To the extent that they are isolated and unchanged since birth, CCKBOs offer direct insights into nebular processes.

Ray and Halo Impact Craters on Ganymede: Fingerprint for Decoding Ganymede's Crustal Structure

Earth and Space Science, Volume 11, Issue 9, September 2024.
Abstract Impact craters are a unique tool not only for inferring ages of planetary surfaces and examining geological processes, but also for exploring subsurface properties. We use ejecta blankets as proxies to obtain insights into the subsurface characteristics and the vertical stratification of Ganymede's icy crust.

Col-OSSOS: Investigating the Origins of Different Surfaces in the Primordial Kuiper Belt

The Planetary Science Journal
The Colours of the Outer Solar System Origins Survey (Col-OSSOS) measured the optical/near-IR colors of a brightness-complete sample of trans-Neptunian objects (TNOs).

Extent of alteration, paleomagnetic history, and infrared spectral properties of the Tarda ungrouped carbonaceous chondrite

Meteoritics &Planetary Science, Volume 59, Issue 9, Page 2411-2431, September 2024.
Abstract Tarda is an ungrouped, hydrated carbonaceous chondrite (C2‐ung) that was seen to fall in Morocco in 2020. Early studies showed that Tarda chemically resembles another ungrouped chondrite, Tagish Lake (C2‐ung), which has previously been linked to the dark D‐type asteroids.

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).
