Our team took part in discovery and follow up programs such as the Canadian-France Ecliptic Plane Survey through observations form the Calar Alto and La Palma observatories back in the first decade of this century. This survey allowed to unveil the dynamical architecture of the outer solar system.

More recently, we have supported and collaborated to the occultation campaign led by J. L. Ortiz (Instituto de Astrofísica de Andalucia. Granada, Spain). This campaign is going on and is obtaining interesting results such as the discovery of rings around small bodies called ‘Centaurs’.
