... INSTRUMENT: SurveyCam FILTERS: Stromgren uvby, 2" square COMMENTS: remote observations are expected BRIEF SCIENCE JUSTIFICATION: Last decade numerous faint structures at the periphery of regular galaxies, as arcs, tails, or streams, have been discovered (see e.g. Martinez-Delgado et al., ... The broad-band photometry is used for observing the faint structures, but it does not allow to break the age-metallicity degeneracy efficiently. ...

Short-Period Comets: Origin and Terrestrial Impact Hazard . ... The model is consistent with the basic observed distributions of near-parabolic comets, short-period comets, Centaurs and high-eccentricity trans-Neptunian objects.This model requires that initial objects in the early Solar System are concentrated to the outer planetary region, and the physical lifetime of comets in the inner planetary region at the present epoch is an increasing function of initial perihelion distances. ...
