Multi-Epoch VERA Observations of Sagittarius A*: I. Images and Structural Variability

Kazunori Akiyama, Rohta Takahashi, Mareki Honma +2

We report the results of multi-epoch observations of Sgr A* with VLBI Exploration of Radio Astrometry (VERA) at 43 GHz, carried out from 2004 to 2008. We detected a time variation…

Counter effects of meridional flows and magnetic fields in stationary axisymmetric self-gravitating barotropes under the ideal MHD approximation: clear examples - toroidal configurations

Kotaro Fujisawa, Rohta Takahashi, Shijun Yoshida +1

We obtain the general forms for the current density and the vorticity from the integrability conditions of the basic equations which govern the stationary states of axisymmetric ma…
