Inner main belt asteroids in Slivan states?

open access: yes, 2015
Context. The spin state of ten asteroids in the Koronis family has previously been determined. Surprisingly, all four asteroids with prograde rotation were shown to have spin axes nearly parallel in the inertial space.

Insights on the Rotational State and Shape of Asteroid (203) Pompeja from TESS Photometry

open access: yesThe Planetary Science Journal
The Main Belt asteroid (203) Pompeja shows evidence of extreme variability in visible and near-infrared spectral slope with time. The observed spectral variability has been hypothesized to be attributed to spatial variations across Pompeja’s surface.

Photometric Lightcurve Analysis of Low-Period Average-Brightness Main-Belt Asteroids

open access: yes
I will be using a telescope to determine the lightcurves of asteroids in the main belt. This is crucial for understanding their shape, surface features, and rotational dynamics.

Lucy L′Ralph In-flight Calibration and Results at (152830) Dinkinesh

open access: yesThe Planetary Science Journal
The L’Ralph instrument is a key component of NASA’s Lucy mission, intended to provide spectral image data of multiple Jupiter Trojans. The instrument operates from ∼0.35 to 4 μ m using two focal plane assemblies: a 350–950 nm multispectral imager, Multi ...

Weak S-type asteroids compared to C-type explain the observed size distribution of the main belt

open access: yesAstronomy & Astrophysics
The main belt, the region between the orbits of Mars and Jupiter, is home to more than 1 million asteroids. These asteroids form orbital groups, (i.e., asteroid families formed by collisions) and also spectral groups (taxonomies) with different chemical ...

Satellite Formation around the Largest Asteroids

open access: yesThe 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 ...

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

open access: yesThe Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

Near-Earth asteroids in main belt-crossing orbits

open access: yesAstronomy & Astrophysics
Aims. We study the dynamical and collisional evolution of Near-Earth asteroids (NEAs) in main belt-crossing orbits (NEACs). Methods. We selected NEACs with H
