- A team of scientists at the Indian Institute of Astrophysics (IIA) have discovered a number of Lithium rich red giants.
- They 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.
- This discovery indicates that Li is being produced in the stars and accounts for its abundance in the interstellar medium.
- The study says that the present amount of Lithium found in the Universe is four times that of the primordial value.
- Lithium (Li), is one of the three primordial elements, apart from Hydrogen and Helium (He), produced in the big bang nucleosynthesis (BBN).
- Identifying sources of Li enrichment in our Galaxy has been a great interest to researchers to validate Big Bang Nucleosynthesis.
- The Big Bang Nucleosynthesis theory predicts that roughly 25% the mass of the Universe consists of Helium.
- The IIA an autonomous institute under the Department of Science & Technology.
