A new study has traced a link between Lithium-rich red giant stars and their enhanced Helium abundance, using data from the Himalayan Chandra Telescope and other archival data. The study gives a new lead to the evolution of cool giant stars along the red giant phase.

This study was published in The Astrophysics Journal as a paper titled "Photospheric Helium Abundance in Cool Giants: A Comprehensive Study", by B. P. Hema and Gajendra Pandey of IIA.
