Recent progress on the structure and dynamics of bulges is reviewed. Those aspects that link galaxy bulges either to oblate spheroids akin to elliptical...
Spheroidal Particle Stability in Semi-Solid Processing
A model for diffusion-controlled spherical particle growth is presented and solved numerically, showing how, on cooling at sufficient rate from a given fraction...
Spin and Relativistic Phenomena Around Black Holes
Since the seminal work of Penrose (1969) and Blandford & Znajek (1977), it has been realized that black hole spin may be an important energy source in...
Spin foam quantization of SO(4) Plebanski's action
The goal of this work is two-fold. In the first part of this paper we regard classical Plebanski's action as a BF action supplemented by constraints. We...
Spin-Alignment and Quasi-Molecular Resonances in Heavy-Ion Collision
Fragment-fragment-$gamma$ triple coincidence measurements of the $^{28}$Si~$+$~$^{28}$Si reaction at E$_{ m c.m.}$~=~55.8 MeV, carefully chosen to populate a...
Spin-driven evolution of asteroids' top-shapes at fast and slow spins seen from (101955) Bennu and (162173) Ryugu
Bennu's and Ryugu's top shapes, which exhibit oblate shapes with equatorial ridges, are considered to have evolved by fast rotation in a longer timescale after...
Spins and shapes of V-type asteroids in the inner Main-Belt
Most basaltic V-type asteroids in the inner Main-Belt are located inside the collisional Vesta family and are considered parts of the fossil planetesimal (4)...
Spins and shapes of V-type asteroids outside the dynamical Vesta family
Vast majority of known V-type asteroids belong to the dynamical Vesta family. A small number of V-types in the mid and outer parts of the Main Asteroid Belt is...
Spins, shapes, and orbits for near-Earth objects by Nordic NEON
The Nordic Near-Earth Object Network (Nordic NEON) observing program was established to obtain knowledge of the physical and dynamical properties of near-Earth...
