Measuring Radial Velocity with Amateur Equipment

AI Thread Summary
Measuring the radial velocity of stars with large exoplanets using amateur equipment is unlikely to yield accurate results. Amateur gear is primarily designed for imaging rather than spectral analysis, which is essential for radial velocity measurements. Obtaining reliable radial velocity data from spectra is complex and typically results in low precision. Professional techniques developed in recent decades have significantly improved the accuracy of these measurements. Therefore, amateur astronomers may face substantial challenges in achieving meaningful results in this area.

Would it be possible to measure the radial velocity of stars with large exoplanets using amateur equipment?

Probably not. Amateur equipment is designed for images, not spectra. Beyond that, getting a RV from a spectrum is tricky and generally gives low-precision results. Only in the past couple of decades have professional techniques emerged that have allowed high-precision RVs needed to detect planets.
 

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?'

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 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
