The effective geometry of the uniformly rotating self-gravitating polytrope
Donato Bini, Christian Cherubini, Simonetta Filippi +1
The \lq\lq effective geometry" formalism is used to study the perturbations of a perfect barotropic Newtonian self-gravitating rotating and compressible fluid coupled with gravitat…
Physical frames along circular orbits in stationary axisymmetric spacetimes
Donato Bini, Christian Cherubini, Andrea Geralico +1
Three natural classes of orthonormal frames, namely Frenet-Serret, Fermi-Walker and parallel transported frames, exist along any timelike world line in spacetime. Their relationshi…
Massless field perturbations of the spinning C metric
Donato Bini, Christian Cherubini, Andrea Geralico
A single master equation is given describing spin test fields that are gauge- and tetrad-invariant perturbations of the {\it spinning C metric} spacetime representing a sou…
Inertial effects in accelerating spacetimes
Donato Bini, Christian Cherubini, Andrea Geralico +1
The motion of test particles along circular orbits in the vacuum metric is studied in the Frenet-Serret formalism. Special orbits and corresponding intrinsically defined geomet…
C metric: the equatorial plane and Fermi coordinates
Donato Bini, Christian Cherubini, Simonetta Filippi +1
We discuss geodesic motion in the vacuum C metric using Bondi-like spherical coordinates, with special attention to the role played by the "equatorial plane." We show that the spat…
On the coherent behavior of pancreatic beta cell clusters
Alessandro Loppini, Antonio Capolupo, Christian Cherubini +4
Beta cells in pancreas represent an example of coupled biological oscillators which via communication pathways, are able to synchronize their electrical activity, giving rise to pu…
