Fast magnetic wave could heat the solar low-beta chromosphere
Yikang Wang, Takaaki Yokoyama, Haruhisa Iijima
Magnetohydrodynamic (MHD) waves are candidates for heating the solar chromosphere, although it is still unclear which mode of the wave is dominant in heating. We perform two-dimens…
A new broadening technique of numerically unresolved solar transition region and its effect on the spectroscopic synthesis using coronal approximation
Haruhisa Iijima, Shinsuke Imada
The transition region is a thin layer of the solar atmosphere that controls the energy loss from the solar corona. Large numbers of grid points are required to resolve this thin tr…
Energy-consistent finite difference schemes for compressible hydrodynamics and magnetohydrodynamics using nonlinear filtering
Haruhisa Iijima
In this paper, an energy-consistent finite difference scheme for the compressible hydrodynamic and magnetohydrodynamic (MHD) equations is introduced. For the compressible magnetohy…
On rising magnetic flux tube and formation of sunspots in a deep domain
H. Hotta, H. Iijima
We investigate the rising flux tube and the formation of sunspots in an unprecedentedly deep computational domain that covers the whole convection zone with a radiative magnetohydr…
Effect of morphological asymmetry between leading and following sunspots on the prediction of solar cycle activity
H. Iijima, H. Hotta, S. Imada
The morphological asymmetry of leading and following sunspots is a well-known characteristic of the solar surface. In the context of large-scale evolution of the surface magnetic f…
Chromospheric polarimetry through multi-line observations of the 850 nm spectral region III: Chromospheric jets driven by twisted magnetic fields
C. Quintero Noda, H. Iijima, Y. Katsukawa +11
We investigate the diagnostic potential of the spectral lines at 850 nm for understanding the magnetism of the lower atmosphere. For that purpose, we use a newly developed 3D simul…
