New star sheds light on formation of heavy elements, universe historyWestyn BranchElliman
the fusion cross-sections for the cases considered.Based on the analysis of these cross-sections, we predict the formation of heavy, superheavy and super-superheavy elements through rapid neutron/light nuclei capture r-process of the nucleosynthesis in astrophysical objects.Patra, S K; Panda, R ...
galaxies and massive black holes formed. They fundamentally transformed the early Universe by endowing it with the first sources of light and chemical elements beyond the primordial hydrogen and helium produced in the Big Bang. The interplay of theory and upcoming observations promises to answer the...
Most stars in today’s Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies1,2. Their formation is still an unsolved problem3,4,5. Infrared/submillimetre-bright galaxies at high redshifts6 have long been suspected to be related to spheroid formation7,8,...
Light-emitting Si nanostructures formed in SiO2 on irradiation with swift heavy ions SiO2 layers containing implanted excess Si are irradiated with Xe ions with an energy of 130 MeV and doses of 3 × 1012–1014 cm−2. In the samples irrad... GA Kachurin,SG Cherkova,VA Skuratov,... ...
Birth of stars and evolution to the main sequence Orion Nebula (M42)Centre of the Orion Nebula (M42). Astronomers have identified some 700 young stars in this 2.5-light-year-wide area. They have also detected over 150 protoplanetary disks, or proplyds, which are believed to be embryonic sola...
The results demonstrate quantitatively an interrelation between heavy-residue mass and element distributions and light-particle multipicities: the mass difference between the observed fragments and the compound nuclei can be explained entirely by the emission of light particles with Z 2. All neutron ...
Brown dwarf, astronomical object that is intermediate between a planet and a star. Brown dwarfs usually have a mass less than 0.075 that of the Sun, or roughly 75 times that of Jupiter. (This maximum mass is a little higher for objects with fewer heavy e
