Shocks, compressible perturbations, and intermittency in the very local interstellar medium: Voyager 1 and 2 observations and numerical modeling
Federico Fraternale, Nikolai V. Pogorelov, Ratan Bera +2
Voyager spacecraft (V1 and V2) provide unique in situ measurements of perturbations propagating beyond the heliopause through the very local interstellar medium (VLISM), including…
Magnetohydrodynamic/Kinetic Modeling of the Interaction between the Solar Wind and the Local Interstellar Medium with He, He, and Pickup H ions and H, He Atoms
Federico Fraternale, Nikolai V. Pogorelov, Ratan K. Bera
The interaction of the solar wind with the local interstellar medium (LISM) spans a wide range of interacting particle populations, energies, and scales. Sophisticated models are r…
Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models
P. Swaczyna, M. Bzowski, K. Dialynas +12
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge exchange collisions in the outer he…
Turbulence in the outer heliosphere
Federico Fraternale, Laxman Adhikari, Horst Fichtner +9
The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates heliospheric regions with sign…
Wave focusing and related multiple dispersion transitions in plane Poiseuille flows
Federico Fraternale, Gabriele Nastro, Daniela Tordella
Motivated by the recent discovery of a dispersive-to-nondispersive transition for linear waves in shear flows, we accurately explored the wavenumber-Reynolds number parameter map o…
Intermittency acceleration of water droplet population dynamics inside the interfacial layer between cloudy and clear air environments
Mina Golshan, Shahbozbek Abdunabiev, Mattia Tomatis +3
We use direct numerical simulation to study the temporal evolution of a perturbation localized on the turbulent layer that typically separates a cloud from the surrounding clear ai…
Sign singularity of the local energy transfer in space plasma turbulence
Luca Sorriso-Valvo, Gaetano De Vita, Federico Fraternale +18
In weakly collisional space plasmas, the turbulent cascade provides most of the energy that is dissipated at small scales by various kinetic processes. Understanding the characteri…
The structure of magnetic turbulence in the heliosheath region observed by Voyager 2 at 106 AU
Federico Fraternale, Nikolai V Pogorelov, John D Richardson +1
It is currently believed that the turbulent fluctuations pervade the outermost heliosphere. Turbulence, magnetic reconnection, and their link may be responsible for magnetic energy…
Magnetic turbulence spectra and intermittency in the heliosheath and in the local interstellar medium
Federico Fraternale, Nikolai V Pogorelov, John D Richardson +1
The understanding of inertial-scale dynamics in the heliosheath is not yet thorough. Magnetic field fluctuations across the inner heliosheath (IHS) and the local interstellar mediu…
Turbulence-driven ion beams in the magnetospheric Kelvin-Helmholtz instability
Luca Sorriso-Valvo, Filomena Catapano, Alessandro Retinò +21
The description of the local turbulent energy transfer, and the high-resolution ion distributions measured by the Magnetospheric Multiscale mission, together provide a formidable t…
Linear waves in sheared flows. Lower bound of the vorticity growth and propagation discontinuities in the parameters space
Federico Fraternale, Loris Domenicale, Gigliola Staffilani +1
This study provides sufficient conditions for the temporal monotonic decay of enstrophy for two-dimensional perturbations traveling in the incompressible, viscous, plane Poiseuille…
Voyager 2 solar plasma and magnetic field spectral analysis for intermediate data sparsity
Luca Gallana, Federico Fraternale, Michele Iovieno +5
The Voyager probes are the furthest, still active, spacecraft ever launched from Earth. During their 38-year trip, they have collected data regarding solar wind properties (such as…
Dispersive to non-dispersive transition and phase velocity transient for linear waves in plane wake and channel flows
Francesca De Santi, Federico Fraternale, Daniela Tordella
In this study we analyze the phase and group velocity of three-dimensional linear traveling waves in two sheared flows, the plane channel and the wake flows. This was carried out b…
Frequency Transient of Three-Dimensional Perturbations in Shear Flows. Similarity Properties and Wave Packets Linear Formation
Federico Fraternale
The present thesis deals with the non-modal linear analysis of 3D perturbations in wall flows. In the first part,a solution to the Orr-Sommerfeld and Squire IVP, in the form of ort…
