The far-ultraviolet main auroral emission at Jupiter – Part 1: Dawn–dusk brightness asymmetries [PDF]

open access: yesAnnales Geophysicae, 2015
The main auroral emission at Jupiter generally appears as a quasi-closed curtain centered around the magnetic pole. This auroral feature, which accounts for approximately half of the total power emitted by the aurorae in the ultraviolet range, is ...

Broken axisymmetry phase of a spin-1 ferromagnetic Bose-Einstein condensate

open access: yes, 2006
A spin-1 ferromagnetic Bose-Einstein condensate subject to a certain magnetic field exhibits a broken-axisymmetry phase in which the magnetization tilts against the applied magnetic field due to the competition between ferromagnetism and linear and ...

Dynamical Evolution of Elliptical Galaxies with Central Singularities

open access: yes, 1997
We study the effect of a massive central singularity on the structure of a triaxial galaxy using N-body simulations. Starting from a single initial model, we grow black holes with various final masses Mh and at various rates, ranging from impulsive to ...

A Photometric Method for Quantifying Asymmetries in Disk Galaxies [PDF]

open access: yes, 1998
A photometric method for quantifying deviations from axisymmetry in optical images of disk galaxies is applied to a sample of 32 face-on and nearly face-on spirals.

Superfluid Rivers in Spinning-down Neutron Stars

open access: yesThe Astrophysical Journal, 2023
We study the motion of neutron superfluid vortices in a spinning-down neutron star, assuming axisymmetry of the flow and ignoring the motion of vortices about the rotation axis.

The Axisymmetric Case for the Post-Newtonian Dedekind Ellipsoids

open access: yes, 2010
We consider the post-Newtonian approximation for the Dedekind ellipsoids in the case of axisymmetry. The approach taken by Chandrasekhar & Elbert (1974, 1978) excludes the possibility of finding a uniformly rotating (deformed) spheroid in the axially ...

The Final Remnant of Binary Black Hole Mergers: Multipolar Analysis

open access: yes, 2010
Methods are presented to define and compute source multipoles of dynamical horizons in numerical relativity codes, extending previous work from the isolated and dynamical horizon formalisms in a manner that allows for the consideration of horizons that ...

Juno Observations of Large‐Scale Azimuthal Fields and Flows in Jupiter's Nightside Magnetosphere: Field‐Aligned Currents, Effective Ionospheric Pedersen Conductivity, and Power to Atmospheric Heating

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Using the methodology of Cowley et al. (https://doi.org/10.1029/2025JA033993), we employ ∼8 years of Juno azimuthal magnetic field data to derive colatitude profiles of Jupiter's nightside (17‐05 hr via midnight) ionospheric equatorward Pedersen current from near the magnetic pole to inner magnetosphere field lines at 18° colatitude, from ...

Numerical modeling and parametric study of a hollow fiber dialyzer using double porous media approach

open access: yesSouth African Journal of Chemical Engineering, 2022
Mathematical modeling is one of the efficient methods to improve the design of hemodialyzer and study affecting parameters on dialyzer performance.In this paper, mathematical modeling of hollow fiber dialyzer is done to investigate the effect of various ...

The Asymmetric Merger of Black Holes [PDF]

open access: yes, 1999
We study event horizons of non-axisymmetric black holes and show how features found in axisymmetric studies of colliding black holes and of toroidal black holes are non-generic and how new features emerge.
