Abstract: The knowledge of the attitude motion of space debris is relevant for active debris removal missions. One possibility to characterize the attitude of space objects consists in the acquisition of photometric measurements over time, called light curves. The observed object is illuminated by the Sun and the variation of its apparent brightness gives in... Show More

Abstract: The formation of the protoplanetary disc is a crucial step in planetary system formation. The study of protoplanetary disk formation is important for understanding the origins of our solar system as well as planets orbiting other stars. Many studies of protoplanetary disc formation focus on the initial properties of the planetary disc, such as mass... Show More
