SUMMARY

Alfvén waves can potentially be observed in stellar spectra using amateur equipment, but significant limitations exist. Observations would likely focus on oscillating hydrogen-alpha (Ha) lines or polarization oscillations. However, achieving the necessary resolution, specifically a resolution (R) of 30,000 or higher, is crucial for detecting phenomena such as Zeeman splitting. Typical amateur equipment may struggle to meet these requirements due to atmospheric interference.

PREREQUISITES
  • Understanding of Alfvén waves in plasma physics
  • Familiarity with stellar spectroscopy techniques
  • Knowledge of hydrogen-alpha (Ha) line characteristics
  • Experience with optical equipment, including gratings and polarizing filters
NEXT STEPS
  • Research the principles of Zeeman splitting and its significance in magnetic field studies
  • Learn about the specifications and capabilities of amateur spectroscopy equipment
  • Explore advanced techniques for enhancing spectral resolution in amateur setups
  • Investigate the effects of atmospheric conditions on stellar spectroscopy
USEFUL FOR

Amateur astronomers, astrophysics enthusiasts, and anyone interested in studying stellar magnetic fields through spectroscopy.

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.
