Reconstructing the size distribution of the primordial Main Belt

, 2017
In this work we aim to constrain the slope of the size distribution of main-belt asteroids, at their primordial state. To do so we turn out attention to the part of the main asteroid belt between 2.82 and 2.96~AU, the so-called "pristine zone", which has

The stepwise rise of angiosperm‐dominated terrestrial ecosystems

Biological Reviews, Volume 100, Issue 5, Page 2131-2149, October 2025.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Compositional Diversity Among Primitive Asteroids

, 2018
Spectroscopic observations from the ultraviolet to the mid-infrared have revealed new and diagnostic differences among primitive asteroids. We review the spectral characteristics of these asteroids and their inferred compositional and physical properties.

Grazing by sea urchins is a potential co‐driver of Greenland kelp forest distribution

Limnology and Oceanography, Volume 70, Issue 9, Page 2756-2766, September 2025.
Abstract Grazing by sea urchins is a main driver of kelp forest dynamics causing shifts from kelp forests to urchin barrens in the temperate region but there is limited information on such patterns from the Arctic region. Based on information from 132 underwater video transects along Greenland's West Coast at 59.9–77.8°N, we explored the distribution ...

Satellite Formation around the Largest Asteroids

The Astrophysical Journal Letters
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have ...

Unexpected D-type Interlopers in the Inner Main Belt

, 2013
Very red featureless asteroids (spectroscopic D-types) are expected to have formed in the outer solar system far from the sun. They comprise the majority of asteroids in the Jupiter Trojan population, and are also commonly found in the outer main belt ...
