Linear Temperature-Mass relation and Local virial relation: Two hypotheses for self-gravitating systems
Y. Sota, O. Iguchi, M. Morikawa +1
We propose two hypotheses which characterize the quasi-equilibrium state that realizes after a cold collapse of self-gravitating system. The first hypothesis is the linear temperat…

Galaxy Distributions and Tsallis Statistical Mechanics
Akika Nakamichi, Izumi Joichi, Osamu Iguchi +1
Large-scale astrophysical systems are non-extensive due to their long-range force of gravity. Here we show an approach toward the statistical mechanics of such self-gravitating sys…
