Thallium

Thallium holds modest yet notable astronomical importance owing to its formation during nucleosynthesis within stars, predominantly arising from phenomena like supernovae explosions and neutron star mergers. Despite its relatively limited cosmic abundance, thallium contributes to the intricate chemical makeup observed in celestial realms. Thallium's distinct spectral lines, particularly across specific wavelengths within the ultraviolet and visible spectra, serve as crucial markers for astronomers in identifying this element within stars and deciphering their compositions and conditions. However, detecting thallium in interstellar spaces or within stars remains challenging due to its lower cosmic prevalence, potentially limiting its detectability using current observational techniques.
