Can Alfvén waves be observed on a stellar spectrum using amateur equipment?

TL;DR

Asking wether Alfvén waves could be observed by amateur astronomers

I currently do amateur stellar spectroscopy, low to medium resolution, and I like to expand further to study magnetic fields near the sun.
I just started studying plasma physics and am aware of Alfvén waves. How would these be observed on a spectrum.? Would it be oscillating Ha lines, or oscillation of polarization? In other words ,what could be observed by an an amateur with grating and polarizing filters? Thanks jack

I don't know the answer to your question but just to observe the zeeman splitting requires and R of 30000 or above. Given the atmosphere I think it would be very difficult with typical amateur equipment.
