Convective Magnetic Flux Emergence Simulations from the Deep Solar Interior to the Photosphere: Comprehensive Study of Flux Tube Twist

Shin Toriumi, Hideyuki Hotta, Kanya Kusano

The emergence of magnetic flux from the deep convection zone plays an important role in the solar magnetism, such as the generation of active regions and triggering of various erup…

Turbulent convection as a significant hidden provider of magnetic helicity in solar eruptions

Shin Toriumi, Hideyuki Hotta, Kanya Kusano

Solar flares and coronal mass ejections, the primary space weather disturbances affecting the entire heliosphere and near-Earth environment, mainly emanate from sunspot regions har…

Which Component of Solar Magnetic Field Drives the Evolution of Interplanetary Magnetic Field over Solar Cycle?

Minami Yoshida, Toshifumi Shimizu, Shin Toriumi

The solar magnetic structure changes over the solar cycle. It has a dipole structure during solar minimum, where the open flux extends mainly from the polar regions into the interp…

Reconstructing the XUV Spectra of Active Sun-like Stars Using Solar Scaling Relations with Magnetic Flux

Kosuke Namekata, Shin Toriumi, Vladimir S. Airapetian +3

Kepler Space Telescope and Transiting Exoplanet Survey Satellite unveiled that Sun-like stars frequently host exoplanets. These exoplanets are subject to fluxes of ionizing radiati…

Probability Distribution Functions of Sunspot Magnetic Flux

Takashi Sakurai, Shin Toriumi

We have investigated the probability distributions of sunspot area and magnetic flux by using the data from Royal Greenwich Observatory and USAF/NOAA. We have constructed a sample…
