Using the Ankara University Kreiken Observatory (AUKR) in Turkey, astronomers have performed high-resolution spectroscopic observations of a metal-poor star known as HD 1936. Results of the observations campaign, published ...
Astronomers have discovered a new stellar system in the outskirts of the Milky Way as part of the Kilo-Degree Survey (KiDS). The newfound system, named Sextans II, is most likely an ultra-faint dwarf galaxy. The finding is ...
An international team of astronomers reports the detection of a new extremely metal-poor star using the Gemini High-resolution Optical SpecTrograph (GHOST) at the Gemini South telescope in Chile. The finding was presented ...
By analyzing the data from various astronomical surveys, astronomers have detected 188,002 candidate metal-poor stars. The discovery, reported in a research paper published March 30 on the arXiv pre-print server, may help ...
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 ...
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 ...
Surprising new data from NASA's Hubble Space Telescope suggests the smooth, settled "brim" of the Sombrero galaxy's disk may be concealing a turbulent past. Hubble's sharpness and sensitivity resolves tens of thousands of ...
