Kappa-like distribution functions inside magnetic clouds

Geofísica Internacional, 2008
En este trabajo estamos interesados en el estudio de la temperatura y el perfil de las colas supratermales de los electrones en nubes magnéticas. Para ello hemos modelado las funciones de distribución de velocidades de los electrones como superposición ...

Harriss Generalized Kappa Distribution: Statistical Modeling and Practical Applications in Finance and Engineering

Engineering Reports
This study presents a four‐parameter distribution which is called the Harris generalized Kappa distribution, which is flexible and tractable. The new distribution extends the two‐parameter Kappa distribution, and it can be explored to model highly skewed

Relativistic regularized kappa distributions [PDF]

Physics of Plasmas, 2022
The special relativistic generalization of isotropic regularized kappa distributions is derived and compared to that of the original Olbertian (or standard) kappa distributions. It is demonstrated that for the latter, the kappa parameter is even more strongly limited than in the non-relativistic case, while for the former, all positive kappa values ...

Scalings for the Alfvén-cyclotron instability in a bi-kappa plasma

Earth and Planetary Physics, 2023
The particle velocity distribution in space plasma usually exhibits a non-Maxwellian high-energy tail that can be well modeled by kappa distributions.

Dissipative Ion-Acoustic Solitary Waves in Magnetized κ-Distributed Non-Maxwellian Plasmas

Physics, 2022
The propagation of dissipative electrostatic (ion-acoustic) solitary waves in a magnetized plasma with trapped electrons is considered via the Schamel formalism.

Effects of Nonextensive Electrons on Dust–Ion Acoustic Waves in a Collisional Dusty Plasma with Negative Ions

Entropy, 2023
The effects of nonextensive electrons on nonlinear ion acoustic waves in dusty negative ion plasmas with ion–dust collisions are investigated. Analytical results show that both solitary and shock waves are supported in this system.
