Palla, Marco (2016) Dinamica di dischi di accrescimento eccentrici e legame con i fenomeni di 'superhump'. [Laurea triennale]
Full text disponibile come:
This thesis investigates the dynamics of accretion disk of SU Ursae Majoris systems and their correlation with the superhump phenomena. The various aspects of the disk eccentricity will be described through a 2D model, which considers the contribution of binary potential, the presence of a Linblad resonance and the viscosity of the disk. After the derivation of the final equation for eccentricity in 2D disks, the computational results will be analysed, these will be compared with the superhump observational evidences and the pros and cons of the model developed will be highlighted.
