In contrast, younger generations of stars consumed the corpses of their predecessors containing heavy elements, which stunted their growth.

In principle, Tanvir says, a bright, well - observed GRB at great distances could expose the makeup of the intergalactic medium as well as the chemistry of the star's host galaxy, which would in turn indicate the products of previous generations of stars.
As a result, the early generations of stars were rich in hydrogen.
«This is particularly important because it indicates that as successive generations of stars die and eject the elements they produced into the galaxy, the heaviest elements are produced together, while previous work had suggested that this was not the case,» Dauphas explained.
In this scenario, some of the stars in the bulge might be younger, with their chemical composition enriched in heavier elements expelled from the death of previous generations of stars, and they should show a different motion compared to the older stars.
But others think the bulge formed later in the galaxy's lifetime, slowly evolving after the first generations of stars were born.

Most galaxies abound with interstellar gas and dust, the detritus of countless generations of stars.
Supernovas are extremely important for cosmic ecology because they inject huge amounts of energy into the interstellar gas, and are responsible for dispersing elements such as iron, calcium and oxygen into space where they may be incorporated into future generations of stars and planets.
Rather, they analyzed microscopic silicon carbide, SiC, dust grains that formed in supernovae more than 4.6 billion years ago and were trapped in meteorites as our Solar System formed from the ashes of the galaxy's previous generations of stars.

In a paper to appear in Publications of the Astronomical Society of Australia, Forbes and Kroupa have offered five possible criteria for determining whether an object is a galaxy: the presence of dark matter, multiple generations of stars, satellite star clusters, a minimum size, and the time it takes for gravitational interactions between stars to slow them all down to roughly the same speed.
