Amazing Start Trek like scanning
I find this stuff truly amazing that the geek squads can look at star's 65,000 light years away and analyse them to such details - go boffins.
Astrophysicists have found evidence that the Milky Way has gobbled up neighbouring massive dwarf galaxies over its 13 billion year lifetime. A team of researchers using a spectroscope analysed the starlight from 28 red giant stars hovering on the outer halo of the Milky Way. They then worked out their chemical composition from …
"J0815+4729 is smaller and has only a millionth part of the calcium and iron that the Sun contains, but it has a relatively large amount of carbon, almost 15 per cent of what is contained in the Sun."
Since you later state "The star [... is ...] amongst the ones with the largest over abundances of carbon,” I suspect that what you intended to say is that it contain 15% more carbon than what is contained in the sun. I also assume that it is all measured in proportion to the mass of the concerned star.
