International team of astronomers publish new findings on the evolution of galactic structures
The image shows NGC6888, a bubble of ionised gas associated with the star WR136. This nebula, which is generated by stellar feedback processes, has the largest temperature inhomogeneities of all the objects studied in this work. This ultimately leads to underestimating the metallicity of these objects. | © Combination of H? and [O III] images of the galactic Wolf-Rayet Ring Nebula NGC 6888, Daniel López Heavy elements like gold, silver, and uranium are apparently more abundant in the Universe than previously assumed. This is the conclusion of an international research team including scientists from the Centre for Astronomy of Heidelberg University that investigated astrophysical processes in star formation regions and particularly the chemical composition of so-called HII regions. According to the researchers, temperature inhomogeneities in these hydrogen-rich gas clouds could be why the abundance of heavy elements is systematically underestimated. ...TO READ THIS ARTICLE, CREATE YOUR ACCOUNT
