The vast majority of Sun like stars are expected to destroy lithium (Li) over the course of their lives. An international team led by Dr. Bharat Kumar Yerra (currently a post-doctoral fellow at NAOC, Beijing) along with Prof. Eswar Reddy (IIA) carried out a large-scale investigation into the Li content of stars in the red clump phase of stellar evolution. They found that all these stars have very high levels of Li for their evolutionary stage, with an increase of a factor of around 40 over the end of the red giant branch phase (the previous stage of their evolution). This suggests that all low-mass stars undergo an Li production phase between the red giant and the red clump stages, when they undergo the helium flash. The new finding is not predicted by the existing theories of stellar evolution, revealing a stark tension between observations and models.
