The triaxiality of odd-mass nuclei is investigated by coupling a quasiparticle to an even-even core through the core-quasiparticle model. Both soft and rigid triaxial cores are considered. “soft core” described collective model with rotation-vibrational motion, while “rigid rotor model, which limiting case only rotational motion. We show that presence odd modifies quadrupole dynamics appear mor...

The aim of this article is to study the existence, location, and stability equilibrium points in a generalized restricted three-body problem (R3BP) that consists an oblate infinitesimal body when primaries are radiating sources with triaxiality two stars surrounded by belt (circumbinary disc). number, collinear triangular Lagrangian depend on mass parameter perturbing forces involved equations ...

A database on shape evolution of direct N -body models formed out of cold, dissipationless collapse is generated using GRAPE and HARP special purpose computers. Such models are important to understand the formation of elliptical galaxies. Three dynamically distinct phases of shape evolution were found, first a fast dynamical collapse which gives rise to the radial orbit instability (ROI) and ge...

The projected shell model analysis is carried out using the triaxial Nilsson+BCS basis. It is demonstrated that, for an accurate description of the moments of inertia in the transitional region, it is necessary to take the triaxiality into account and perform the three-dimensional angular-momentum projection from the triaxial Nilsson+BCS intrinsic wavefunction.
