Giant Planet Migration through the Action of Disk Torques and Planet-planet Scattering
This paper presents a parametric study of giant planet migration through the combined action of disk torques and planet-planet scattering. The torques exerted on planets during Type II migration in circumstellar disks readily decrease the semi-major axes a, whereas scattering between planets increases the orbital eccentricities ǫ. This paper presents a parametric exploration of the possible par...
متن کاملElectrostatic and Magnetostatic Solutions in a Lorentz-Violating Electrodynamics Model
We propose an effective Lorentz violating electrodynamical model via static de Sitter metric which is deviated from Minkowski metric by a minuscule amount depending on the cosmological constant. We obtain the electromagnetic field equations via the vierbein decomposition of the tensors. In addition, as an application of the electromagnetic field equations obtained, we get the solutions of elect...
متن کاملOn the singularities of the electrostatic and magnetostatic dipole fields
The singular behaviour of the electrostatic dipole field is compared with that of the magnetostatic one, with pedagogical access to the difference between the two established without necessarily resorting to certain advanced differentiation identities involving delta functions. Such an approach may be more suitable for a regular curriculum in electrodynamics. It is rather common in many standar...
متن کاملHohenberg-Kohn theorems in electrostatic and uniform magnetostatic fields.
The Hohenberg-Kohn (HK) theorems of bijectivity between the external scalar potential and the gauge invariant nondegenerate ground state density, and the consequent Euler variational principle for the density, are proved for arbitrary electrostatic field and the constraint of fixed electron number. The HK theorems are generalized for spinless electrons to the added presence of an external unifo...
متن کاملOn the average of electrostatic and magnetostatic elds , the singularities of dipole elds and depolarizing elds
In Classical Electrodynamics [1] a theorem is proved on the average of an electrostatic or magnetostatic eld over a spherical volume. The proof of the theorem is based on an expansion in spherical harmonics and it is useful for deriving the singular behaviour of dipole elds. In this paper we give a simple proof of this theorem, the key element being to use reciprocity. The method also highlight...
