Dynamo instabilities in plasmas with inhomogeneous chiral chemical potential
Jennifer Schober, Igor Rogachevskii, Axel Brandenburg
We study the dynamics of magnetic fields in chiral magnetohydrodynamics, which takes into account the effects of an additional electric current related to the chiral magnetic effec…
Production of a chiral magnetic anomaly with emerging turbulence and mean-field dynamo action
Jennifer Schober, Igor Rogachevskii, Axel Brandenburg
In relativistic magnetized plasmas, asymmetry in the number densities of left- and right-handed fermions, i.e., a non-zero chiral chemical potential mu_5, leads to an electric curr…
Non-locality of the Turbulent Electromotive Force
Abhijit B. Bendre, Kandaswamy Subramanian
The generation of large-scale magnetic fields () in astrophysical systems is driven by the mean turbulent electromotive force (), the cros…
Discovery of an Edge-on Circumstellar Debris Disk Around BD+45598: a Newly Identifed Member of the Pictoris Moving Group
Sasha Hinkley, Elisabeth C. Matthews, Charlène Lefevre +24
We report the discovery of a circumstellar debris disk viewed nearly edge-on and associated with the young, K1 star BD+45598 using high-contrast imaging at 2.2m obtain…
Cepheids with giant companions. I. Revealing a numerous population of double-lined binary Cepheids
Bogumił Pilecki, Grzegorz Pietrzyński, Richard I. Anderson +5
Masses of classical Cepheids of 3 to 11 M are predicted by theory but those measured, clump between 3.6 and 5 M. As a result, their mass-luminosity relation is poorly…
Relic gravitational waves from the chiral magnetic effect
Axel Brandenburg, Yutong He, Tina Kahniashvili +2
Relic gravitational waves (GWs) can be produced by primordial magnetic fields. However, not much is known about the resulting GW amplitudes and their dependence on the details of t…
