OORT-Cloud and Kuiper-Belt Comets

, 1998
This paper follows the broadly accepted theory that Oort-Cloud Comets originated in the Solar Nebula in the general region where the major planets, Jupiter and Saturn, were formed while the Kuiper-Belt Comets originated farther out where the temperatures

Superposition of Doppler‐Shifting Magnetopause Kelvin‐Helmholtz Modes Through Dynamic Mode Decomposition of a Global MHD Simulation

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.

Second‐Scale Formation of Non‐Field‐Aligned Plasma Irregularities Observed From a High‐Altitude 43‐Cassiopeiids Fireball

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

The Role of Planetary Rotation in Polar Cusp Localization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

A survey of possible missions to the periodic comets in the interval 1974 - 2010

, 1974
Catalogs are developed to survey the mission possibilities for the short period comets. In the first the physical and pertinent orbital characteristics are given for 65 short period comets. The second catalog is one containing the predicted perihelia for
