Temporal Evolution of Sunspot Groups and Increase in the Open Flux during Solar Maximum in Cycle 24

Minami Yoshida, Toshifumi Shimizu, Shin Toriumi, Haruhisa Iijima

Abstract The evolution of the global solar magnetic field directly impacts the interplanetary magnetic field (IMF). During the solar maximum of Cycle 24, the monthly averaged IMF strength doubled over five Carrington rotations (CRs) in late 2014. To understand the physical origin …

What Determines the Brightness of the Magnetically Open Solar Corona?: Insights from Three-dimensional Radiative Magnetohydrodynamic Simulations and Observations

Haruhisa Iijima

Abstract We investigate the relationship between solar coronal holes and open-field regions using three-dimensional radiative magnetohydrodynamic simulations combined with remote-sensing observations from the Solar Dynamics Observatory (SDO). Our numerical simulations reveal that magnetically open regions in the corona can exhibit brightness comparable …

Synthetic Ca ii 8542 Å Stokes Profile Associated with Chromospheric Magnetic Reconnection in a Simulated Active Region

T. Yokoyama, Haruhisa Iijima, Takuma Matsumoto, Shin Toriumi et autres

Abstract Magnetic reconnection is an important driving mechanism of many chromospheric phenomena, e.g., UV bursts and chromospheric jets. Information about magnetic fields is indispensable for analyzing chromospheric magnetic reconnection, which is mainly encoded in polarization signals. The purpose of this work is …

Magnetic reconnection sustains the mass budget of the solar wind

Yajie Chen, Hardi Peter, Damien Przybylski, Haruhisa Iijima et autres

The solar wind originates from open magnetic field regions on the Sun, but the processes relevant to its origin remain unsolved. We present a self-consistent numerical model of the source region of the wind, in which jets similar to those observed on …

Comparison of Polar Magnetic Fields Derived from MILOS and MERLIN Inversions with Hinode/SOT-SP Data

Masahito Kubo, Daikou Shiota, Yukio Katsukawa, M. Shimojo et autres

The detailed investigation of the polar magnetic field and its time evolution is one of the major achievements of Hinode. Precise measurements of the polar magnetic field are essential for understanding the solar cycle, as they provide important constraints for identifying the …
