| Most metal-poor star hints at universe's first supernovae Posted: 24 Sep 2014 10:50 AM PDT In a new study, researchers point out that the elemental abundance of the most iron-poor star can be explained by elements ejected from supernova explosions of the universe's first stars. This reveals that massive stars, which are several tens of times more immense than the Sun, were present among the first stars. |
| Most stars are born in clusters, some leave 'home' Posted: 24 Sep 2014 08:26 AM PDT New modeling studies demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars. |
