- The question regarding the production of lithium in stars has been solved by Indian researchers.
- Stars actually destroy lithium as they evolve into red giants.
- Planets were known to have more lithium than their stars.
- However, some stars were found that were lithium-rich.
- When stars grow beyond their Red Giant stage it is known as the Red Clump stage.
- Here they produce lithium.
- It is known as a Helium Flash.
- The study also challenges the present understanding of nucleosynthesis in stars.
- The Big Bang Nucleosynthesis theory predicts that roughly 25% the mass of the Universe consists of Helium.
- The present abundance of lithium in the universe is only four times the original (Big Bang) value.
- Lithium is commonly used today in communication device technology.
- It was first produced in the Big Bang, around 13.7 billion years ago when the universe came into being, along with other elements.
