Detection of Close Kuiper Belt Binaries with HST WFC3

The 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 ...

Reassessing the Relationship Between Meteor Radio Afterglows and Optical Persistent Trains

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract Meteor radio afterglows (MRAs) and optical persistent trains (PTs) are two types of long‐lived phenomena which are occasionally observed following the occurrence of a meteor. Both phenomena are thought to be produced by intrinsic emission mechanisms; PTs have been associated with chemiluminescent reactions between meteoric metals and ...

The absolute magnitude distribution of cold classical Kuiper belt objects

, 2016
International audienceWe report measurements of the low inclination component of the main Kuiper Belt showing a size freqency distribution very steep for sizes larger than H_r ~ 6.5-7.0 and then a flattening to shallower slope that is still steeper than ...

Size, Shape, Density, and Atmospheric Limit of (50000) Quaoar Revealed from 14 years of Stellar Occultation

The Astrophysical Journal
We present results from 28 stellar occultations by the large trans-Neptunian object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultation dataset, along with nine other published events, we were able to fit ...

The Transition to Tectonic Control of Magmatism in the East African Rift System—The 20 Ma Samburu Event

Tectonics, Volume 44, Issue 9, September 2025.
Abstract The Samburu Series magmas of the East African Rift System are a key component of the Early Miocene magmatic resurgence, marking the initiation of plate‐scale volcanic events associated with extension, distinct from the prior continental flood basalt episodes.

Considering Contact Forces during the Formation of Planetesimals by Gravitational Collapse: Mutual Orbits, Spin States, and Shapes

The Astrophysical Journal
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N -body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of superparticles. Previously published numerical

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs

The Anatomical Record, Volume 308, Issue 5, Page 1349-1368, May 2025.
Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

Evolution and architecture of an exhumed ocean‐facing coarse‐grained submarine canyon fill, Baja California, Mexico

Sedimentology, Volume 72, Issue 1, Page 189-226, January 2025.
ABSTRACT Present day submarine canyons are active conduits for the transfer of large volumes of sediment, carbon and pollutants from continents to oceans. However, the evolution of submarine canyons over geological timescales remains poorly understood due to their erosional nature and low preservation potential. The Late Cretaceous Punta Baja Formation
