The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained
A. Brandenburg, A. Johansen, P. A. Bourdin +34
The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equ…
Strong nonlocality variations in a spherical mean-field dynamo
A. Brandenburg, P. Chatterjee
To explain the large-scale magnetic field of the Sun and other bodies, mean-field dynamo theory is commonly applied where one solves the averaged equations for the mean magnetic fi…
The Sun's interior structure and dynamics, and the solar cycle
A. -M. Broomhall, P. Chatterjee, R. Howe +2
The Sun's internal structure and dynamics can be studied with helioseismology, which uses the Sun's natural acoustic oscillations to build up a profile of the solar interior. We di…
Challenges and Insights in Growing Epitaxial FeSn Thin Films on GaAs(111) substrate Using Molecular Beam Epitaxy
P. Chatterjee, M. Nord, J. He +2
FeSn is a room-temperature antiferromagnet composed of alternating Fe3Sn kagome layers and honeycomb Sn layers. Its distinctive lattice allows the formation of linearly dispersing…
Reynolds stress and heat flux in spherical shell convection
P. J. Käpylä, M. J. Mantere, G. Guerrero +2
(abridged) Context. Turbulent fluxes of angular momentum and heat due to rotationally affected convection play a key role in determining differential rotation of stars. Here we per…
Development of twist in an emerging magnetic flux tube by poloidal field accretion
P. Chatterjee, A. R. Choudhuri, K. Petrovay
Following an earlier proposal by Choudhuri (2003) for the origin of twist in the magnetic fields of solar active regions, we model the penetration of a wrapped up background poloid…
