With only about half of its mass remaining, it will shrink to a fraction of its radius and become a white dwarf star.
White dwarfs are common, the most famous one being the companion to the brightest star in the sky, Sirius.
The result is consistent with the current age estimates for the thick disc but also suggests that the current minimum age estimate might be increased.
Additional measurements are needed to refine the age range, and the scientists predict that large-scale sky surveys now underway will significantly increase the number of non-cluster white dwarfs and enable the determination of their parameters.
They also were at increased risk of depression, eating disorders and engaging in risky sexual behavior.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
These programs, she added, should be targeted to students starting in elementary school.
“One of the things that we need to do better at society is to have conversations very early with young people – both females and males – about healthy relationship strategies,” Bonomi said.
As remnants of some of the oldest stars in the galaxy, white dwarfs offer an independent means of dating the lifetimes of different galactic populations.
A globular cluster is a roughly spherical ensemble of stars (as many as several million) that are gravitationally bound together and typically located in the outer regions of galaxies.
