AI Thread Summary
To calculate the magnitude of a binary star system, the individual magnitudes of the stars must be known. If there are multiple binary systems, the total magnitude can be derived from the individual magnitudes of all stars involved. The formula for combining magnitudes is used, taking into account the number of stars and their respective brightness. The discussion emphasizes the importance of knowing whether the system consists of one or multiple binaries. Accurate calculations depend on the specific details of the binary systems in question.

How do we calculate the magnitude of a system composed by some binary systems of stars?
 
Astronomy news on Phys.org
You need to give us more information. *Some* binary systems? How many? Just one binary, or multiple binaries?

Do you know the magnitudes of the individual stars in the binary or binaries?
 
Yeah, suppose we know the magnitude of all the stars and that the number of binary systems is k (can be one or more).
 

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.
