Maximum count for mutually bound stars

In summary, there is no theoretical limit to the maximum number of stars bound in a system under mutual attraction in the early universe. However, the average size of bound star systems may increase with time due to the bottom-up growth of structure. The role of dark matter in the binding process also needs to be considered. Galaxies are bound systems of stars with a significant contribution from dark matter, while globular clusters are primarily bound by stars alone and tend to be composed of older stars in the outskirts of galaxies.

Especially in the early universe, what do you think would be the maximum number of stars bound in a system under mutual attraction?

I don't see any reason for a theoretical limit to this, though the growth of structure happens bottom-up, so the average size of bound star systems should increase with time. It also begs the question of whether you're allowing dark matter to assist in the binding. Galaxies are bound systems of stars, but it's not only the stars that do the binding. Globular clusters, on the other hand, do not have a detectable amount of dark matter, so they are probably the largest systems bound primarily by stars.

And they are composed of very old stars, and prefer the suburbs. I see a pattern emerging.
 

Related to Maximum count for mutually bound stars

What is the maximum count for mutually bound stars?

The maximum count for mutually bound stars is not a fixed number and can vary depending on the specific system and conditions. However, studies have shown that most stable, mutually bound star systems contain two to three stars.

How are stars mutually bound?

Stars can become mutually bound when they form in close proximity to each other and are gravitationally attracted to one another. This can result in them orbiting around a common center of mass, forming a stable system.

Can more than three stars be mutually bound?

Yes, it is possible for more than three stars to be mutually bound in a star system. However, this is less common and can be more unstable compared to systems with two or three stars.

What factors affect the maximum count for mutually bound stars?

The maximum count for mutually bound stars can be affected by various factors such as the mass and distance between the stars, their orbits, and the overall stability of the system. Other external factors such as interactions with nearby stars or the presence of a third body can also impact the maximum count.

Why is studying mutually bound stars important?

Studying mutually bound stars can provide valuable insights into the formation and evolution of star systems, as well as the dynamics of multiple body systems. This can also help us better understand the behavior of stars in the universe and how they interact with each other.
