Astrophysics/Solar magnetic field


How the solar magnetic field intensity varies mathematically after solar explosions?
How high is this solar magnetic intensity near the earth, before and after solar explosions?
How affect the changes of solar magnetic field the earth magnetic field?

Please provide links to papers related to these topics.

Thank you very much

The magnetic field is impossible to mathematically quantify exactly after a solar explosion.  It is the result of wild fluctuations in the magnetic field itself.  You should check for day-to-day information on the magnetic field of the Sun near the Earth.  As far as the direct impact, it's not a massive effect.  What really seems to be the issue is the impact of a large amount of material (a coronal mass ejection) from the Sun during the explosion, which follows later.  That material (this is slightly out of my regular field, which focuses on nuclear reactions) impacts is very large, and the extent to which a magnetic field "sticks" to a material is proportional to the square of the basic dimension of the material.  Therefore, our geomagnetic storms are more related to that than they are directly related to the changes in the solar magnetic field itself.

Fusion, solar flares, cosmic rays, radiation in space, and stellar physics questions. Generally, nuclear-related astrophysics, but I can usually point you in the right direction if it's not nuclear-related or if it's nuclear but not astrophysics.


Just moved from being a physics professor at the University of Texas of the Permian Basin into government work. Doctoral dissertation was on a reaction in CNO-cycle fusion, worked in gamma-ray astronomy in the space science division of the naval research laboratory in the high-energy space environment branch.

Government work as a physical scientist with a nuclear focus.

Ph.D. in physics, research was on nuclear fusion reactions important in stellar fusion, further work on space telescope technology.
