The researchers knew how much UV light should come independently from a blue straggler
and from a white dwarf.
The re-invigorated stars are called blue stragglers
, and their high mass and brightness are properties that lie at the heart of this study.
can exist singly, but like other stars they may have companions.
are so named because they seem to lag behind in the ageing process and look much younger than the population from which they are formed.
Will Clarkson (Indiana University and UCLA), who led the study, says that while blue stragglers
are common in globular clusters, this is the first time they've been clearly identified in the bulge.
Yet, astronomers have found resident bright stars, known as blue stragglers
, that are nearly twice as massive as the sun and one-tenth the age of the clusters.
Washington, December 24 (ANI): A new study has shown that stars known as blue stragglers
have been rejuvenated by a sort of "cosmic facelift", courtesy stellar collisions and a process sometimes called vampirism.
Although considered a straggler
, the capture of the fish led to the discovery of the first documented population, off the remote Comoros Islands.
A lone straggler
tried to sneak out of the main battle area in Marawi at 1:30 p.
That means if a given blue straggler
formed with the rest of its star cluster, it should have died billions of years ago," Knigge said.
The Stardust Race and Sports Book, a bit north of the newer establishments yet one of the more famous gathering places for crusty hardcore bettors since the mid '70s, had most of its 300 seats claimed by daybreak - much to the disappointment of one hefty straggler
who came through the glass doors with a couple of bags of McGriddled food-stuff from the nearby McDonald's in one hand, two long-neck Budweisers in the other and scraps of newspapers and notes tucked under his arm.
Many researchers believe the typical blue straggler
arises from two elderly, lower-mass stars that collided and merged to form a massive, hotter star.
Brawner said the straggler
was killed because he fought it out the government troops.
The only thing that was clear is that at least two stars must be involved in the creation of every single blue straggler
, because isolated stars this massive simply should not exist in these clusters," said Dr Christian Knigge from Southampton University, who led the study.
No one came forward and told us they had seen anything, so our guess is that it was a straggler
who came into the church when it was empty and did it for a laugh.
