On the Border: Searching for Cometary Activity near the Centaur–JFC Transition Line

open access: yesThe Planetary Science Journal
Current wide-field surveys discover ∼15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover many asteroids that have distant JFC-like orbits, but with no reported ...

Asteroid Mass Estimation by Mutual Perturbations During Close Encounters After Gaia Focused Product Release

open access: yesThe Astronomical Journal
Mutual perturbations between asteroids during close encounters allow the estimation of their masses using precise astrometric observations. We use all astrometry reported to the Minor Planet Center, high-precision astrometry from ESA’s Gaia Focused ...

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.
