An application of the tensor virial theorem to hole + vortex + bulge systems
R. Caimmi
The tensor virial theorem for subsystems is formulated for three-component systems and further effort is devoted to a special case where the inner subsystems and the central region…
Two-component, ideal, self-gravitating fluids: the fractional virial potential energy
R. Caimmi, T. Valentinuzzi
Two-component, ideal, self-gravitating fluids are conceived as macrogases, and the related equation of state is expressed using the virial theorem for subsystems, under the restric…
The G-dwarf problem in the Galaxy
R. Caimmi
The empirical differential metallicity distribution (EDMD) is deduced for (i) local thick disk stars; (ii) likely metal-weak thick disk stars; (iii) chemically selected local G dwa…
R fluids
R. Caimmi
A theory of collisionless fluids is developed in a unified picture, where nonrotating figures with anisotropic random velocity component distributions and rotating figures with iso…
Why there are no elliptical galaxies more flattened than E7: thirty years later
R. Caimmi
Elliptical galaxies are modelled as homeoidally striated Jacobi ellipsoids where the peculiar velocity distribution is anisotropic, or equivalently as their adjoints configurations…
Holes within galaxies: the egg or the hen?
R. Caimmi
Unsustained matter distributions unescapely collapse unless fragmentation and centrifugal or pressure support take place. Starting from the above evidence, supermassive compact obj…
