    Observation Wave
AI Thread Summary
Amateur stellar spectroscopy can potentially observe Alfvén waves, but significant challenges exist. Detecting these waves may involve identifying oscillating Ha lines or changes in polarization. However, achieving the necessary resolution, particularly for observing Zeeman splitting, typically requires equipment with a resolution of 30,000 or higher. Given atmospheric conditions and the limitations of standard amateur equipment, successful observation may be difficult. Overall, while the interest in studying magnetic fields and Alfvén waves is notable, practical observation with amateur tools remains limited.

TL;DR Summary
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.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
