Indian Astrophysicists: Lithium in Interstellar space & Red Giants have Connection

The Researchers in the Indian Institute of Astrophysics frame a connection between Lithium in interstellar space and lithium in red giants. The Lithium rich Helium burning stars also have connections with red giant stars.

Highlights

A team of scientists at the Indian Institute of Astrophysics have discovered a number of Lithium rich red giants. The study says that the present amount of Lithium found in the Universe is four times that of the primordial value. Primordial means existing from the beginning time. This, in fact is the primary reason for scientists to identify Lithium rich sources. Finding such sources will help in validating Big Bang Nucleosynthesis

Bing Bang Nucleosynthesis

The Big Bang Nucleosynthesis is the production of nuclei other than that of the lightest isotope of hydrogen (1H – Hydrogen 1) during an early phase of the Universe. This includes helium-4, helium-3, lithium-7.

After Hydrogen and Helium, it is lithium that is present in abundance in the universe.
