There are at least five blue stragglers in the cluster.

Many open clusters also play host to what have been called "blue stragglers."

Such collisions can produce what are known as blue stragglers.

These stars are so crowded that they can, at times, slam into each other and even form a new star, called a "blue straggler."

In 1964 he proposed mass transfer mechanism as an explanation of blue straggler stars.

They became what we call 'blue stragglers,' with surface temperatures five or six times as hot as our own Sun.

M80 contains a relatively large number of blue stragglers, stars that appear to be much younger than the cluster itself.

Such stars are said to be blue stragglers.

The resulting rejuvenated star, massive and very blue, is called a blue straggler.

These celestial objects of mystery are called blue stragglers, for they appear somehow to have fallen behind in normal stellar evolution.

It has a rich population of blue stragglers that are strongly concentrated toward the center of Terzan 7.

With this new technology, astronomers discovered that some stars, known as "blue stragglers", appeared younger than other stars in the cluster.

While astronomers can spot the results of the collisions, the blue straggler stars, they almost certainly will never see the collisions.

It enveloped its partner, and the two stars spiraled together, merging into one superstar - a blue straggler.

A blue straggler is formed from the merger of two stars, possibly as a result of an encounter with a binary system.

"While the blue straggler story may seem odd, you do see them in the Milky Way, and most stars are in multiple systems," Brown says.

Correspondingly, the core region contains a concentration of interaction-formed blue straggler stars, most of which formed 2-5 billion years ago.

Blue stragglers have also been identified in a few low-density clusters and in the peripheries of some other dense clusters.

All known SX Phoenicis variables in globular clusters are blue straggler stars.

The primary component in this system is a blue straggler, which is a type of star that is created by the interaction between two or more stars.

(Cf. blue stragglers) A likely scenario is a collision with a binary star system, or between two binary systems containing white dwarfs.

However, four of the blue stragglers in the cluster were about 1.6 times the mass of the Sun, so they presumably represent the mergers of two stars.

In globular clusters a few stars known as blue stragglers are observed, apparently continuing the main sequence in the direction of brighter, bluer stars.

Mostly composed of old, yellow stars, it does possess a contingent of blue stragglers, young stars that are hypothesized to form from binary star mergers.

For years after Dr. Sandage made the first sightings, so little was known about blue stragglers because few could be observed, and those few defied theory.
