N ov 2 00 4 Does solar structure vary with solar magnetic activity ?
We present evidence that solar structure changes with changes in solar activity. We find that the adiabatic index, Γ 1 , changes near the second helium ionization, i.e., at a depth of about 0.98R ⊙. We believe that this change is a result of the change in the effective equation of state caused by magnetic fields. Inversions should be able to detect the changes in Γ 1 if mode sets with reliable ...
متن کاملDeciphering solar magnetic activity: on grand minima in solar activity
The Sun provides the energy necessary to sustain our existence. While the Sun provides for us, it is also capable of taking away. The weather and climatic scales of solar evolution and the Sun-Earth connection are not wellunderstood. There has been tremendous progress in the century since the discovery of solar magnetism—magnetism that ultimately drives the electromagnetic, particulate, and eru...
متن کاملOn Solar Radius Variation with magnetic Activity
In response to the claim by Dziembowski et al. (2001) that the solar radius decreases with magnetic activity at the rate of 1.5 km yr, we consider the theoretical question whether a radius variation is expected with the solar cycle. If the radius variation is caused by the magnetic pressure of toroidal flux tubes at the bottom of the convection zone, then the dynamo model of Nandy and Choudhuri...
متن کاملDeciphering Solar Magnetic Activity: Spotting Solar Cycle 25
We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes. They had starting points that are asymmetrically offset in each hemisphere at times that are 21–22 years after the corresponding, same polarity, activity bands of solar cycle 23 started their migration. Those bands define the so-called “extended solar ...
متن کاملDoes a Non-magnetic Solar Chromosphere Exist?
Enhanced chromospheric emission which corresponds to an outwardly increasing semiempirical temperature structure can be produced by wave motion without any increase in the mean gas temperture. Hence, the sun may not have a classical chromosphere in magnetic eld free internetwork regions. Other signiicant diierences between the properties of dynamic and static atmospheres should be considered wh...
