Molecular Gas in NUclei of GAlaxies (NUGA): IV. Gravitational Torques and AGN Feeding
S. Garcia-Burillo, F. Combes, E. Schinnerer +2
We discuss the efficiency of stellar gravity torques as a mechanism to account for the feeding of the central engines of four low luminosity AGN: NGC4321, NGC4826, NGC4579 and NGC6…
Acceleration of weakly collisional solar-type winds
I. Zouganelis, N. Meyer-Vernet, S. Landi +2
One of the basic properties of the solar wind, that is the high speed of the fast wind, is still not satisfactorily explained. This is mainly due to the theoretical difficulty of t…
Topology and Phase Transitions II. Theorem on a necessary relation
Roberto Franzosi, Marco Pettini
In this second paper, we prove a necessity Theorem about the topological origin of phase transitions. We consider physical systems described by smooth microscopic interaction poten…
Topology and Phase Transitions I. Preliminary Results
Roberto Franzosi, Marco Pettini, Lionel Spinelli
In this first paper, we demonstrate a theorem that establishes a first step toward proving a necessary topological condition for the occurrence of first or second order phase trans…
Stochastic processes, galactic star formation, and chemical evolution. Effects of accretion, stripping, and collisions in multiphase multi-zone models
G. Valle, S. N. Shore, D. Galli
This paper reports simulations allowing for stochastic accretion and mass loss within closed and open systems modeled using a previously developed multi-population, multi-zone (hal…
A detailed study of the rotating toroids in G31.41+0.31 and G24.78+0.08
Maria T. Beltran, Riccardo Cesaroni, Roberto Neri +4
We present the results of high angular resolution millimeter observations of gas and dust toward G31.41+0.31 and G24.78+0.08, two high-mass star forming regions where four rotating…
