Samarium

Samarium holds astronomical significance primarily within the context of nucleosynthesis and its spectral characteristics aiding in unraveling stellar compositions. Belonging to the lanthanide group, samarium is forged during rapid neutron capture (r-process) occurrences within stars, notably in phenomena like supernovae and neutron star mergers. Despite its status as a relatively less abundant element in the cosmic tapestry compared to more prevalent ones, samarium's spectral lines span diverse wavelengths, encompassing the ultraviolet, visible, and infrared spectra. This spectral footprint enables astronomers to detect and scrutinize samarium's presence in cosmic environments, offering crucial insights into the elemental makeup of stars and celestial bodies.
