PublicaciónThe visible and near-infrared spectra of asteroids in cometary orbits
Context. Dynamical and albedo properties suggest that asteroids in cometary orbits (ACOs) are dormant or extinct comets. Their study provides new insights for...

PublicaciónThermal properties of slowly rotating asteroids: results from a targeted survey
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper...

PublicaciónThermophysical modeling of asteroids from WISE thermal infrared data - Significance of the shape model and the pole orientation uncertainties
In the analysis of thermal infrared data of asteroids by means of thermophysical models (TPMs) it is a common practice to neglect the uncertainty of the shape...
