On the convergence of an algorithm constructing the normal form for lower dimensional elliptic tori in planetary systems
Antonio Giorgilli, Ugo Locatelli, Marco Sansottera
We give a constructive proof of the existence of lower dimensional elliptic tori in nearly integrable Hamiltonian systems. In particular we adapt the classical Kolmogorov's normali…

Physical properties of the jet from DG Tauri on sub-arcsecond scales with HST/STIS
L. Maurri, F. Bacciotti, L. Podio +5
We derive the physical properties at the base of the jet from DG Tau both along and across the flow and as a function of velocity. We analysed seven optical spectra of the DG Tau j…

Quasi-periodic motions in a special class of dynamical equations with dissipative effects: a pair of detection methods
Ugo Locatelli, Letizia Stefanelli
We consider a particular class of equations of motion, generalizing to n degrees of freedom the "dissipative spin--orbit problem", commonly studied in Celestial Mechanics. Those eq…
