Geometric properties of galactic discs with clumpy episodes
Leandro Beraldo e Silva, Victor P. Debattista, Tigran Khachaturyants +1
A scenario for the formation of the bi-modality in the chemical space [/Fe] vs [Fe/H] of the Milky Way was recently proposed in which -enhanced stars are produced early and q…
The discreteness-driven relaxation of collisionless gravitating systems: entropy evolution and the Nyquist-Shannon theorem
Leandro Beraldo e Silva, Walter de Siqueira Pedra, Monica Valluri
The time irreversibility and fast relaxation of collapsing -body gravitating systems (as opposed to the time reversibility of the equations of motion for individual stars or par…
The discreteness-driven relaxation of collisionless gravitating systems: entropy evolution in external potentials, N-dependence and the role of chaos
Leandro Beraldo e Silva, Walter de Siqueira Pedra, Monica Valluri +2
We investigate the old problem of the fast relaxation of collisionless -body systems which are collapsing or perturbed, emphasizing the importance of (non-collisional) discreten…
Statistical mechanics of self-gravitating systems: mixing as a criterion for indistinguishability
Leandro Beraldo e Silva, Marcos Lima, Laerte Sodré +1
We propose an association between the phase-space mixing level of a self-gravitating system and the indistinguishability of its constituents (stars or dark matter particles). This…
