A generalized energy-consistent finite difference scheme for 10-moment magnetohydrodynamics
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Pressure anisotropy and off-diagonal pressure stresses are ubiquitous and play important roles in collisionless/weakly collisional plasmas. The Chew-Goldberger-Low (CGL) MHD model…
Vector Apodizing Phase Plates for the ELT: From prototype to final optics for METIS and MICADO
J. A. van den Born, R. Landman, D. S. Doelman +12
The first generation of instruments for the upcoming Extremely Large Telescope (ELT) will allow for the direct imaging of exoplanets that were previously below the sensitivity or r…
Investigation of Solar Wind Speed Characteristics Using IPS Observations and the PFSS+SCS Model
Kyogo Tokoro, Munehito Shoda, Shinsuke Imada
Understanding the relationship between solar wind speed and global coronal magnetic field is essential for space-weather forecasting and provides key diagnostics of the underlying…
Radial evolution of Alfvén wave Parametric Decay Instability in the near-Sun solar wind: Effects of Temperature Anisotropy
Hayato Saguchi, Yohei Kawazura, Munehito Shoda +1
Parametric decay instability (PDI) of Alfvén wave is thought to play an important role in the dissipation of the large-amplitude Alfvén waves and in the heating of magnetized plasm…
Chromospheric turbulence as a regulator of stellar wind mass flux
Munehito Shoda, Tom Van Doorsselaere, Allan Sacha Brun
The mass flux of solar and stellar winds is a key quantity for stellar evolution and space weather, yet its physical regulation mechanism remains an unsolved problem. In particular…
Magnetic switchback formation: a review of proposed mechanisms
Peter F. Wyper, Jonathan Squire, Etienne Pariat +19
Magnetic switchbacks are large amplitude deflections of the magnetic field within the solar wind. They are Alfvénic in character and so are associated with a spike in velocity and…
Multi-hierarchy simulation of Riemann problem for reconnection exhausts
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Magnetic reconnection drives a wide range of astrophysical plasma phenomena, including solar flares, by converting magnetic energy into plasma energy through changes in magnetic fi…
Proposal of a Novel Physical Parameter Characterizing Solar Wind Speed in a Wave-Driven Model
Kyogo Tokoro, Munehito Shoda, Shinsuke Imada
Empirical solar wind speed models play an important role in enabling space weather forecasting with low computational cost. Among these, one model called WS model is based on the a…
