Satellites alter the spin-axis precession rate of their host planet. The tidal migration of moons is therefore an efficient driver…

Estimating the level of noise in time series using entropy methods – Andrea Scarciglia (Università di Pisa)
Identification of underlying noise in time series is essential for applications ranging from physiology to econometrics, with relevance in all…
Chaos maps and study of the Geminids meteor shower – Ariane Courtot (Observatoire de Paris)
Meteor showers originate from a parent body, an asteroid or a comet. This parent body ejects several meteroids, forming a meteoroid stream, which will then meet the Earth. From Earth, several meteors can then be observed. To prove they form a shower, we then need to prove whether they come from the same source.…
Non-homogeneous persistent random walks and averaged environment for the Lévy-Lorentz gas – Giampaolo Cristadoro (Università di Milano-Bicocca)
I will first introduce a model known in the physical literature as the Lévy-Lorentz gas. The model describes the continuous-time motion of a particle on the real line in the presence of a random array of marked points, whose nearest-neighbor…
Asteroid families identification: history and state of the art – Dr. Zoran Knezevic (Astronomic Observatory of Belgrade)
The history of asteroid families, from their discovery back in 1918, until the present time, is briefly reviewed. Two threads have been followed: on the development of the theories of asteroid motion and the computation of proper elements, and on…
A ridiculously short crash course in infinite ergodic theory with a view towards the question of mixing – Marco Lenci (Università di Bologna)
This is a two-hour seminar, with the first part dedicated to introducing basic concepts in infinite ergodic theory.…
