From the article, link to actual study and emphasis:
The study, led by Northwestern University and a team of international researchers, suggests that the magnetic field actually generates 20,000 miles below the surface. This was discovered after the team ran a series of complex calculations on a NASA supercomputer. It’s worth noting that these are just initial findings and more research is required to confirm the data.
It’s definitely going to be interesting to see the additional studies and findings that follow up because of this.
Is this going to necessitate a redefinition of the heliosheath or heliopause, since those are partially based on the solar magnetic field?
No. They’re both… way outside of the sun, so the depth within the sun at which the magnetosphere is generated is immaterial to them.
I was just thinking that since the centre of those was on/in the Sun, this shift might make a difference, but that makes sense.
