Stellar Forcing of (exo)Planetary Environments
Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13
The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…
Turbulent Diffusion of Magnetic Field Lines in the Heliosphere
J. V. A. Joubert, R. D. Strauss, J. Light +2
Due to solar wind turbulence, Parker spirals are stochastic. The dispersion of magnetic field lines is described by a convection-diffusion equation for the field line density distr…
Are the Parker and Focused Transport Equations Equivalent for Galactic Cosmic Ray Modulation?
J. P. van den Berg, N. E. Engelbrecht, R. D. Strauss
The Parker transport equation (TPE) has been the equation of choice for the past 60 years in studies of galactic cosmic ray (GCR) modulation. Conversely, the focused TPE describes…
An Evaluation of Different Numerical Methods to Calculate the Pitch-angle Diffusion Coefficient from Full-orbit Simulations: disentangling a rope of sand
J. P. van den Berg, P. L. Els, N. E. Engelbrecht
The pitch-angle diffusion coefficient quantifies the effect of pitch-angle scattering on charged particles propagating through turbulent magnetic fields and is a key ingredient in…
A detailed survey of the parallel mean free path of solar energetic particle protons and electrons
J. T. Lang, R. D. Strauss, N. E. Engelbrecht +4
In this work, more than a dozen solar energetic particle (SEP) events are identified where the source region is magnetically well-connected to at least one spacecraft at 1~au. The…
Jovian electrons in the inner heliosphere: Opportunities for Multi-spacecraft Observations and Modeling
R. D. Strauss, N. Dresing, N. E. Engelbrecht +11
In this paper we explore the idea of using multi-spacecraft observations of Jovian electrons to measure the 3D distribution of these particles in the inner heliosphere. We present…
Impact of Cosmic Rays on Atmospheric Ion Chemistry and Spectral Transmission Features of TRAPPIST-1e
Konstantin Herbst, Andreas Bartenschlager, John Lee Grenfell +10
Ongoing observing projects like the James Webb Space Telescope (JWST) and future missions offer the chance to characterize Earth-like exoplanetary atmospheres. Thereby, M-dwarfs ar…
Spectroscopic Imaging of the Sun with MeerKAT: Opening a New Frontier in Solar Physics
Devojyoti Kansabanik, Surajit Mondal, Divya Oberoi +7
Solar radio emissions provide several unique diagnostics to estimate different physical parameters of the solar corona, which are otherwise simply inaccessible. However, imaging th…
