Blue Stragglers Stars (BSSs) are thought to form in globular clusters by two main formation channels: i) mergers induced by stellar collisions and ii) coalescence or mass-transfer between. Abstract. This chapter explores how we might use the observed statistics of blue stragglers in globular clusters to shed light on their formation. This means we will touch on topics also discussed elsewhere in this book, such as the discovery and implications of bimodal radial distributions and the “double sequences” of blue stragglers that have recently been found in some by: 1.

Abstract I view field blue stragglers (FBS) through the prism of an aging observer. This chapter contains my impressions and perspectives about the current state of knowledge about FBSSs, drawn from an extensive literature that I searched with the aid of the NASA Astrophysics Data System, and Google.   This is an efficient method of producing single blue stragglers, provided that a large population of close binaries exists in the cluster. Case B mass transfer involves a main-sequence star accreting material from a more evolved companion and thus could be a likely explanation for blue stragglers in short-period spectroscopic binaries, such as Cited by:

Use features like bookmarks, note /5(). Blue stragglers (BSS) are main-sequence stars in open or globular clusters that are more luminous and bluer than stars at the main-sequence turn-off point for the cluster. Blue stragglers were first discovered by Allan Sandage in while performing photometry of the stars in the globular cluster M3.

Saffer. Blue stragglers are stars that stay on the main sequence longer Blue Stragglers book expected. They even appear to regress from “old age” back to a hotter and brighter “youth,” gaining a new lease on life.

The existence of blue straggler stars, which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution. Such stars should have exhausted their nuclear fuel and evolved long ago to become cooling white dwarfs. Blue stragglers: Astronomers discover how mysterious stars stay so young Scientists report that a mechanism known as mass transfer explains the origins of these old stars that still burn hot and blue.

Blue stragglers are still there though, like they were too lazy to leave the MS. How they are formed and where they go when they finally evolve are two questions still up for debate (bite1, bite2).

The authors of today’s paper studied the blue stragglers in Blue Stragglers book cluster 47 Tucanae with the aim of shedding some light on the subject. The existence of blue straggler stars, which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution.

Such stars should have exhausted their nuclear fuel and evolved long ago to become cooling white dwarfs. They are found to exist in.

Blue stragglers are concentrated in the core of the cluster and are about 10 times (3 mags) dimmer than the blue stars that are apparent in these images. So I'm not sure how you fix this problem, but APOD itself made the same mistake of claiming the blue stars in the image to be blue stragglers.

they aren't, they are Horizontal Branch Stars. Blue stragglers can exist solo, but they may also have companions. In this case, the companion’s mass is a red flag on the stellar evolutionary trail, because each origin scenario predicts.

The formation of blue stragglers This illustration demonstrates the two ways that blue stragglers — or "rejuvenated" stars — in globular clusters form. The upper illustration shows the collision model where two low-mass stars in an overcrowded environment experience a head-on collision, combining their fuel and mass and to form a single hot.

Blue stragglers are stars that stay on the main sequence longer than expected. They even appear to regress from “old age” back to a hotter and brighter “youth,” gaining a new lease on life.

The most flagrant blue stragglers are stars that cannot be older than one or two billion years, lurking in the cores of 13 billion year-old GLOBULAR CLUSTERS. The origin(s) and evolution of these puzzling objects are the central challenges confronting researchers in this : Shara, M.

The book Blue by Joyce Hostetter is realistic fiction because it is filled with real life struggles 14 year old Ann faces. I enjoyed it because when I read about Anns life I feel like its me in the book and I can visualize everything that is going on.

Also it tells you about realistic things that happened years ago/5. Blue stragglers, according to NASA, "are older stars that acquire a new lease on life when they collide and merge with other stars."1 But a new study calls into question whether stellar collisions can account for these remarkable stars.

And blue stars burn their fuel so quickly that they actually look young. Since their discovery, evolutionary astronomers have sought a way to explain how these.

Blue stragglers long have been suspected to be living in our galaxy’s bulge, but had not been observed because younger stars in the disk of our galaxy lie along the line of sight to the core.
