Disk Winds Driven by Magnetorotational Instability and Dispersal of Proto-Planetary Disks (2008)
By performing local three-dimensional MHD simulations of stratified accretion disks, we investigate disk winds driven by MHD turbulence. Initially given weak vertical magnetic fields are effectively...
Magnetic Landscape of Sun's Polar Region (2008)
Tsuneta, S., Ichimoto, K., Katsukawa, Y., Lites, B. W., Matsuzaki, K., Nagata, S., ...
We present the magnetic landscape of the polar region of the Sun that is unprecedented in terms of high spatial resolution, large field of view, and polarimetric precision. These observations were...
We review our recent results of global one-dimensional (1-D) MHD simulations for the acceleration of solar and stellar winds. We impose transverse photospheric motions corresponding to the...

Alfven Wave-Driven Supernova Explosion (2007)
Suzuki, T. K., Sumiyoshi, K., Yamada, S.
We investigate the role of Alfven waves in the core-collapse supernova (SN) explosion. We assume that Alfven waves are generated by convections inside a proto-neutron star (PNS) and emitted from its...
Cascading of Fast-Mode Balanced and Imbalanced Turbulence (2006)
Suzuki, T. K., Lazarian, A., Beresnyak, A.
We study the cascading of fast MHD modes in magnetically dominated plasma by performing one-dimensional (1D) dynamical simulations. We find that the cascading becomes more efficient as an angle...
Collisionless Damping of Fast MHD Waves in Magneto-rotational Winds (2005)
Suzuki, T. K., Yan, H., Lazarian, A., Cassinelli, J. P.
We propose collisionless damping of fast MHD waves as an important mechanism for the heating and acceleration of winds from rotating stars. Stellar rotation causes magnetic field lines anchored at...
A low upper-limit on the lithium isotope ratio in HD140283 (2004)
Aoki, W., Inoue, S., Kawanomoto, S., Ryan, S.G., Smith, I.M., Suzuki, T.K., ...
