Astronomers report the discovery of a new ultra-metal-poor star as part of the Southern Photometric Local Universe Survey (S-PLUS). The newly found star, designated SPLUS J210428.01−004934.2, turns out to have the lowest ...
An international team of astronomers has detected a new ultra metal-poor star with the lowest ever measured abundance of iron. Designated SMSS J160540.18−144323.1, the newly found object is the most iron-deficient star ...
EPFL astrophysicists actively participated in the discovery of a very rare star, which is particularly old and metal-poor. As a messenger from the distant past, it will allow the scientists to learn more about the young universe, ...

Massachusetts Institute of Technology (MIT) astronomers have detected 18 very metal-poor stars in the Sagittarius dwarf galaxy. They found that one of the stars from the sample has an extremely low metallicity, slightly below ...
By analyzing spectroscopic data, astronomers have investigated the globular cluster Omega Centauri, aiming to find a population of stars with very low metallicity. The study resulted in the detection of the 11 most metal-poor ...
An international team of researchers has conducted a chemical study of six new very metal-poor star candidates in the Sloan Digital Sky Survey Data Release 12 (SDSS DR12). The new research, available in a paper published ...
Researchers from the Instituto de Astrofísica de Canarias (Spain) and the University of Cambridge (UK) have detected lithium (Li) in the ancient star J0023+0307, a main-sequence extremely iron-poor dwarf star about 9,450 ...
