چکیده

The effect of the advection of magnetic features on synoptic frames has been estimated and it shows that for the time interval ranging from 4 to 14 days the differential rotation of magnetic features accounts for most of the surface transport of photospheric magnetic fields. It is shown that both the 1996.08.27 19:12:30 synoptic frame with the effect of differential rotation included and the footpoint area and the neutral line calculated on the basis of the new synoptic frame differe slightly from that without differential rotation. To determine the improvement made by including the effect of magnetic features’ differential rotation, more samples are needed to compare with observed coronal structures.

Thermal Convection in a (Kuvshiniski-type) Viscoelastic Rotating Fluid in the Presence of Magnetic Field through Porous Medium (TECHNICAL NOTE)

  The effect of magnetic field on an incompressible (Kuvshiniski-Type) viscoelastic rotating fluid heated from below in porous medium is considered. For the case of stationary convection, magnetic field and medium permeability have both stabilizing and destabilizing effect on the thermal convection under some conditions whereas rotation has a stabilizing effect on the thermal convection. In the...

The dependence of the magnetic field strength of a sunspot umbra on its intensity and brightness temperature

A partial decrease of the convective energy by the magnetic field of a sunspot causes the temperature of the magnetized plasma to decrease and this leads to a magneto-hydrostatic equilibrium. Thus, we expect a strong relation between magnetic field strength of a sunspot and its temperature/brightness. Here, we investigate this relation in the umbra of the large sunspot in NOAA10930 using spectr...

Earth’s Magnetic Field for Spacecraft Attitude Control Applications (TECHNICAL NOTE)

In this paper the earth’s magnetic field is simulated precisely while the intensity and direction of the field are verified with one of the standard references for selected points on the earth and the results are compared with some low-order models. In another simulation, the complete model is compared with a common approximate model. The magnetic field in orbital frame is described and to empl...

The analysis of magnetic field measurements of T Tau

It is shown that the existence of hot accretion spots at the surface of T Tau practically has no effect on the accuracy of estimation of its magnetic field strength at photospheric level. We also found that one can interpret results of T Tau's photospheric magnetic field strength measurements carried out via different methods in the frame of the following alternative: 1) if T Tau's inclination ...
