NIRwave: A wave-turbulence-driven solar wind model constrained by PSP observations
Güdel, M.; Boro Saikia, S.; Bartel, M. +2 more
Aims: We generate a model description of the solar wind based on an explicit wave-turbulence-driven heating mechanism, and constrain our model with observational data.
Methods: We included an explicit coronal heating source term in the general 3D magnetohydrodynamic code NIRVANA to simulate the properties of the solar wind. The adapted h…
Particle monitoring capability of the Solar Orbiter Metis coronagraph through the increasing phase of solar cycle 25
Gissot, S.; Sasso, C.; Romoli, M. +26 more
Context. Galactic cosmic rays (GCRs) and solar particles with energies greater than tens of MeV penetrate spacecraft and instruments hosted aboard space missions. The Solar Orbiter Metis coronagraph is aimed at observing the solar corona in both visible (VL) and ultraviolet (UV) light. Particle tracks are observed in the Metis images of the corona…
Influence of the interstellar magnetic field and 11-year cycle of solar activity on the heliopause nose location
Bladek, Piotr; Ratkiewicz, Romana
Context. The heliosphere is formed by the interaction between the solar wind (SW) plasma emanating from the Sun and a magnetised component of local interstellar medium (LISM) inflowing on the Sun. A separation surface called the heliopause (HP) forms between the SW and the LISM.
Aims: In this article, we define the nose of the HP and investig…
HCS background magnetic field study HYTARO+
Hidalgo, M. A.; Blanco, J. J.; Arrazola, D.
Context. HYTARO+ is an analytical model developed to evaluate the influence of the solar magnetic dipole in the topology of the local structure of the heliospheric current sheet (HCS).
Aims: Statistical methods such as MVA, which are typically used in the study of the HCS come with two limitations. On one hand, they do not provide any informa…
The nature of the solar wind electron temperature and electron heat flux. II. Case of a spiral interplanetary magnetic field
Salem, Chadi S.; Pulupa, Marc; Hubert, Daniel
Aims: We aim to analyze the solutions of the solar wind electron energy equation in a spherical expansion with a spiral interplanetary magnetic field (IMF), a radial power law of the electron heat flux with a constant index α, and a constant or a smooth increase of the solar wind speed.
Methods: Generic analytical electron temperature pr…
