How do blue stragglers form?

Answer 1

There are several theories as to how blue stragglers form.

A blue straggler is a massive star, usually two or three times larger than other stars in the cluster, that doesn't fit into the size range of other stars in an open or globular cluster.

A possible explanation for their arrival is that the cluster may have taken them hostage, but this seems improbable.

The most common explanation for blue stragglers is that they are created when two stars collide and merge; these could be binary stars. Since blue stragglers are frequently found in the densely populated regions of clusters, it is most likely that star collisions are the cause of these occurrences.

Answer 2

The term "blue stragglers" refers to stars that appear bluer and more luminous than their surroundings due to processes like mass transfer from a companion star, stellar collisions, or mergers that occur in dense stellar environments like globular clusters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
